Beschreibung: Some fifty years after the Snellius I expedition (1929-1930) a Dutch-Indonesian joint expedition is carried out (1984-1985) in the Eastern Indonesian archpelago. Based on two months (September -October 1984) of research at nine different reef localities, a first report will be presented on the general morphology, composition and condition of recent and fossil reefs of these areas. The research areas that will be discussed are the following: Ambon: In the bay of Ambon fringing and patch reefs heavily damaged by silting up, caused by soi1. erosion on the island. North East Ambon an elevated reef from the old Pleistocene. Lucipara islands: Exposed very isolated atoll with some sand cays. Tukang Besi islands: Atoll reefs of Kaledupa. Binongko reef terraces; fossil cliffs modelled from massive Pleistocene reef limestone by coastal abrasion during tectonic uplift of the island; extensive reef terrace dating from the last interglacial; living reef not at the moment constructive. Sumba: East Sumba fringing reefs with influence of land and population. Young Pleistocene reef near Melolo, older terraces higher up. Komodo: Various fringing and patch reefs bordering the east side of the National Park of Komodo. Current swept reefs in the strait of Linta. Gililawa Laut and Tinandja lo~r Miocene reefs. Sumbawa: Fringing reefs in Telok Moti Toi and Sanggar bay near Tambora volcano (erupted in 1815). Coral growth in Bima bay. Pleistocene reef north east of Bima. Taka Bone Rate: Large pseudo atoll with small sand cay reefs (e.g. Tinandja) exposed reefs, coral banks and lagoons. Salayer: fringing reefs at west coast around islands Guang and Sahuluan. Pliocene reefs on both islands; Bahuluan with volcanic core. Sulawesi: Coral reef complex on the shallow shelf off South West Sulawesi, with three rows of reefs, most emerging as sand cay reefs. Because of young Holocene reg~ession in front of Ujung Pandang. Influence of sedimentation and population. Apart from these investigations during the Snellius II expedition, a long term project has been carried out since 1979 in the last area mentioned. A continuation of reef research is planned there, in close cooperation with UnHas (University of Ujung Pandang). The presentation of results will be accompanied by maps and photographs.

Beschreibung: -The problems of reconstructing historical relationships for areas of endemism from distributional data for groups of taxa and the cladistic relationships among the members of those groups can be solved by applying the two principles of parsimony and mutual inclusion or exclusion (compatibility) of components. Components can be extracted from a data matrix by means of transcription into partial monothetic sets. The data matrix thus derived represents the distribution over areas for the monophyletic groups in one or more cladograms. It is derived from two different matrices by boolean multiplication. The first matrix gives the binary representation of distributions of taxa over areas of endemism; the second describes the cladogram for the same taxa, in terms of character states converted into binary form by additive binary coding. The derived data matrix can be used in historical biogeography to represent the given phyletic data ( Assumption 0 here newly defined), and can be amended to reflect Assumptions 1 or 2 to accomodate the problems of wide-spread taxa and missing areas. Areacladograms are determined from the derived matrix by searching for the largest sets of mutually compatible components. Area-cladograms are evaluated in terms of support (vicariance) and contradiction (ad hoc interpretations such as dispersal and extinction). Area-cladograms that best fit the data matrix regarding the balance between support and contradiction are selected as the best possible recontructions of relationships among the areas of endemism. The procedure is illustrated by the example of the poeciliid fish genera Heterandria and Xiphophorus, and several other standard examples.

Beschreibung: Aublet based Tontelea and its only named species, T. scandens, on material he collected in French Guiana, illustrated as pl. 10 in the original publication. Aublet’s specimens are incorporated in the herbarium of J. J. Rousseau (now located in the Paris Herbarium in herbier Denaiffe) and also in the Herbarium of the British Museum. The sheet in herbier Denaiffe was identified by Lanjouw and Uittien (1940) as the original for Aublet’s pl. 10, which shows a flowering twig, analysis of a flower, and a detached leaf much larger than the leaves on the twig. From a photograph of this sheet it appears that the inflorescence is reproduced only in fragmentary form in the drawing. In the latter the inflorescence is represented as a rather short, few-branched, flowering twig, whereas in the specimen the inflorescence is strictly dichotomously branched many times with occasional supernumerary branches in the leaf axils. The sheet also has four detached leaves.

Beschreibung: This catalogue provides an annotated listing of the liverworts and hornworts from the Guianas (Guyana, Surinam, French Guiana), based on the literature and on new data that have become available in the framework of the “Flora of the Guianas” project. In total 375 species in 93 genera are recorded, including more than 100 species and 28 genera new to the Guianas. A list of synonyms (including 30 new ones), a systematic arrangement of the genera and families, and an index to the collectors are also given.

Beschreibung: Haesselia roraimensis gen. et spec. nov. (Cephaloziaceae) from the foot of Mt. Roraima (Guyana) is described and figured. The new genus has been assigned to the subfamily Trabacelluloideae together with Fuscocephaloziopsis Fulf. and Trabacellula Fulf., two other neotropical genera of Cephaloziaceae with convex leaves.

Beschreibung: Chemical analysis of representatives of about thirty genera of Lejeuneaceae has shown that the terpenoid and flavonoid content of the Lejeuneaceae is basically comparable to that of other Hepaticae and quite diversified. Among the terpenoids detected, some are common throughout the family (elemenenes, germacrenes), others are distributed more restrictedly and are indicative of evolutionary relationships among genera, e.g. borneols (Nipponolejeunea), pinguisanines (Acrolejeunea complex), striatenes (Ptychanthoideae, Omphalanthus complex), calamenanes ( Lopholejeunea) and labdanes (Ptychanthus, Tuzibeanthus). Flavonoids are present in smaller amounts than terpenoids and comprise some compounds unique to bryophytes (lutonarin, kaempferol-3-methylether). The genus Omphalanthus stands out by its total inability to biosynthesize flavonoids. At the species level the chemical constitution may vary considerably and in some species evidence for the existence of chemical races was detected.

Beschreibung: A revision has been made of the hepatic genus Brachiolejeunea (Spruce) Schiffn. (family Lejeuneaceae, subfamily Ptychanthoideae). Within this genus two subgenera were recognised: subg. Brachiolejeunea and subg. Plicolejeunea Schust. (n order to distinguish taxonomic entities within these subgenera and to evaluate their affinities, the morphology and anatomy of the gametophyte and the sporophyte have been studied. Data on cytology and sporeling development, obtained from living and cultured specimens, were added. Sporophyte characters have been studied with light microscopy (LM) and scanning electron microscopy (SEM). Besides a considerable reduction in the number of accepted species, the main result of this study is that the traditional delimitation of Brachiolejeunea cannot be maintained. The two subgenera appear to be different in many characters, several of them new, and are accordingly elevated to generic level. The genus Brachiolejeunea (4 species) now comprises only the former subgenus of that name; the generic name Frullanoides Raddi is reinstated for the subg. Plicolejeunea (7 species and 1 subspecies). For both genera the morphology and anatomy are described, the previously neglected sporophyte generation being treated in particular detail. In each of the genera a different type of sporophyte is present; a “fenestrate-type” in Frullanoides, a “nodular-type” in Brachiolejeunea. From a of the distribution patterns it appears that both genera probably originated in the western part of Gondwanaland. Brachiolejeunea is confined to that area and may presently be characterized as a Neotropical-montane element. One species of Frullanoides is pantropical, the others are neotropical. The species of Brachiolejeunea are predominantly epiphytes of mountain forests and have a rather narrow drought tolerance; the species of Frullanoides generally occur in a greater variety of habitats and have a wider drought tolerance. A consideration of generic relationships shows that the affinities of genera are very different. For both genera identification keys are provided, each species and subspecies is illustrated and for each taxon the following information is provided: synonymy with relevant literature and typification, a description, geographical distribution with distribution map, and notes on ecology, differentiation and variation. The second part of this study contains a short review of the genus Blepharolejeunea S. Arnell, which has been emended to accommodate several diverging species of Brachiolejeunea and Dicranolejeunea. Blepharolejeunea is related to both genera and is characterized as a Neotropical-montane element. In the third part of this study the sporophyte generation in the subfam. Ptychanthoideae is analysed with Scanning Electron Microscopy. Fenestratetype and nodular-type sporophytes are described and the different affinities of these types are discussed. The new tribe Brachiolejeuneae van Slageren & Berendsen is created to accommodate the genera of Ptychanthoideae with nodular-type sporophytes.

Beschreibung: The entries have been split into five categories: (a) Algae — (b) Fungi & Lichens — (c) Bryophytes — (d) Pteridophytes — (e) Spermatophytes & General subjects. — Books have been marked with an asterisk.

Beschreibung: Palawan, the most forested and least botanically known island in the Philippines was explored by an international expedition from March 1 to May 31, 1984. The sponsors were the Swedish Match Hilleshog Philippines Inc. and the Ministry of Natural Resources of the Philippines. Palawan separates the South China and Sulu Seas and forms a land bridge between Sabah and Mindoro in the Philippines. It is ca. 440 by 4.5—42 km, laying approximately between 8° and 12° North. There is a mountainous backbone, broken in two places, throughout its length with the three highest peaks at 2085 m (Mt. Mantalingajan), 1798 m (Mt. Victoria) and 1593 m (Cleopatra’s Needle).

Beschreibung: The Annotated Flora of Kairiru by Bro. O.W. BORRELL (Marcellin College, Bulleen, Australia) has been allocated A$ 3000 by the Papua New Guinea Biological Foundation towards its publication. Brother William is retouching the drawings and hopes for a speedy publication of the Flora. Appreciation of soil fertility by the Dayaks of Central Kalimantan, J. Agric. Trad. & Bot. Appl.

Beschreibung: Please notify the Editor of the Flora Malesiana Bulletin of any change in address which he will be glad to communicate here if of interest to the readers. Mr. R. ABDULHADI (BO) worked for a year at Brisbane to obtain his Ph.D.

Beschreibung: Herbarium Bogoriense. A fourth floor has been added to the building. Bogor Botanic Gardens. Two heavy storms occurred, one in October, which uprooted 161 trees, among which some of the famous kalong trees, and another one in November, 1984, which blew down or so damaged about 130 trees that they had to be felled.

Beschreibung: The sole object of the present work is to furnish a monograph dealing exclusively with the species of the genus Psathyrella (exclusive of Lacrymaria, see Chapter VI) reported from the Netherlands, France and the British Isles. Ever since 1958 we intensively collected, described, depicted and stored in our herbarium these species from many parts of the Netherlands and later studied the exsiccata microscopically. From 1960 on we did the same practically every year for some three weeks in many parts of the British Isles, often during the annual forays of the British Mycological Society, and particularly in Wales and Scotland. Moreover through the valuable aid from Dr. D. A. Reid, Dr. D. N. Pegler and Dr. R. Watling and the information supplied by the ‘New Check List of British Agarics and Boleti’ (Dennis, Orton & Hora, 1960) we became very well acquainted with the British species of Psathyrella. Mr. H. Romagnesi’s vast knowledge of and experience with the French species of Psathyrella and the great co-operation between him and us resulted in our becoming extensively informed about the French species of the genus. Our frequent exchanges of information and exsiccata even led to Romagnesi’s discovery of a new species (P. phegophila Romagn.) in his own herbarium, which he very kindly publishes in the present work. The results of our observations on Psathyrella in the three countries of course were compared with those published by A. H. Smith in his monograph on the North American species, hitherto the only monograph of this genus.

Beschreibung: A description is given of the floristic composition of communities with Hordeum marinum in the South-west Netherlands. This reveals that this species, one of the character-taxa of the alliance Saginion maritimae, is especially represented in transition situations towards saline habitats with environmental instability through treading, sudden inundations and drainage, embankment, etc. Permanent plot studies showed great resemblance in succession during recovery of damaged vegetation. Hordeum manifests itself in the early developmental stages, together with Parapholis strigosa. Ecological affinities between the Saginion species are discussed in relation to salinity and silt content of the soil. Contrary to the other species, H. marinum prefers high salinities combined with a relatively high silt content of the sandy substrate.

Beschreibung: A survey is presented of past treatment of the genus Ctenitis C. Chr. in the Old World, with the conclusion that the genus has not hitherto been clearly defined. A new generic description covering the species of Asia, Malesia and the Western Pacific is presented, with a new division of the species into two subgroups of informal status, based on scales and spores, and a key to all species. Seventeen new species are described, one new name proposed and four new combinations made. A list of species in the region which, in the opinion of the author, have been wrongly included in Ctenitis, is appended.

Beschreibung: In connection with the forthcoming revision of the Coniferae for the Flora Malesiana, the author thought it necessary to revise the genus Podocarpus. Although this genus has a substantial representation in Malesia (30 species), the revision is too involved to be appropriate with the Flora Malesiana per se. One new subgenus and 17 new sections are described, and 94 species are enumerated, of which 11 species and 1 variety are described as new, and 3 varieties have been raised to specific rank. Two keys are given to the 18 sections; each section has a key to the species.

Beschreibung: A third species of the hypogean genus Curassanthura Kensley, 1981 (Isopoda, Anthuridea, Paranthuridae) is described from a cave on Bermuda. C. bermudensis n. sp. is very similar to C. halma Kensley, 1981, hitherto known from Curaçao, and now also recorded from new localities on Bonaire.

Beschreibung: Surface sediment samples taken by box corer from 45 stations on the Norwegian continental margin and in the Norway Basin have been investigated for their benthic foraminiferal content. Unlike previous studies, the living benthic foraminiferal fauna was differentiated from empty tests comprising the foraminiferal death assemblage. Factor analysis of both the living and dead faunal data reveals six living species assemblages and five corresponding dead assemblages. The additional living assemblage is characterized by the arenaceous species Cribrostomoides subglobosum that dominates between 1400 and 2000 m water depth, but is rare in the dead faunal data.Trifarina angulosa and, to a lesser extent, Cibicides lobatulus characterize the shallowest foraminiferal assemblage from 200 to 600 m water depth, where it is associated with strong bottom currents and warm, saline Atlantic water of the North Atlantic Drift. On the slope between 600 and 1200 m water depth, the Melonis zaandami Species Assemblage dominates, particularly in areas characterized today by rapid sedimentation of terrigeneous material. Between 1000 and 1400 m depth, where the slope is covered by fine grained, organic-rich, terrigeneous mud, the living foraminiferal assemblage is characterized by Cassidulina teretis and Pullenia bulloides. Below 1400 m, three foraminiferal assemblages are found: C. subglobosum is found from 1400 to 2000 m, Cibicidoides wuellerstorfi and Epistominella exigua predominantly live from 2000 to 3000 m water depth, and below 3000 m, Oridorsalis umbonatus and Triloculina frigida dominate the fauna.All of the Elphidium excavatum tests found in this study and the Cassidulina reniforme tests found above 500 m water depth were found to be reworked.Analysis of the sediment grain-size distribution and the organic carbon content in surface samples from the deepest stations suggest that the abundance of C. wuellerstorfi and E. exigua is positively correlated to relatively coarse (caused by planktic foraminifera) and organic-rich sediments, whereas high frequencies of O. umbonatus and T. frigida coincide with low organic carbon content. We suggest that C. wuellerstorfi is adapted to deep-sea environments with relatively high food supply, tolerating relatively low interstitial water oxygen content, whereas O. umbonatus may tolerate lower food supply prefering well-oxygenated interstitial waters.

Beschreibung: Rates of respiration and growth were measured for larvae of the spider crab H. araneus reared in the laboratory from hatching to metamorphosis. The moulting cycle was simultaneously monitored. In both zoeal instars individual respiration rate (R) increased as a linear function of time (t) of development, whereas growth, measured as dry weight (W), carbon (C), nitrogen (N), hydrogen (H), and energy content (E, calculated from C) followed a power function of t. Weight-specific respiration rate (QO sub(2)) was in all instars maximum in early postmoult, and minimum in intermoult and early premoult. Zoea II and megalopa instars showed another conspicuous QO sub(2) increase during late premoult. Respiration (both R and QO sub(2)) and growth of the megalopa could be described by non-linear (quadratic) functions of t. R and QO sub(2) during this larval stage were not correlated with W, but were controlled by events of the moulting cycle: R followed a similar pattern to QO sub(2) (minimum values in intermoult), whereas biomass of the megalopa changed conversely, with a maximum in intermoult and early premoult.

Beschreibung: Effects of feeding and starvation on the moult cycle and on the ultrastructure of hepatopancreas cells were studied in Stage I lobster larvae (H. americanus Milne-Edwards). The relative significance of yolk and first food was quite different in larvae originating from two females. Most larvae from one hatch were, in principle, able to develop exclusively with yolk reserves (without food) to the second instar. The larvae from the second hatch showed lecithotrophic development only to the transition between late intermoult and early premoult (Stages C/D sub(0) of Drachs's moult cycle) of the first larval instar. When initial starvation in this group lasted for 3 days or more, the point of no return (PNR) was exceeded. After the PNR, consumption of food was still possible, but development ceased in the transition C/D sub(0) or in late premoult (D sub(3-4)). Examination of hepatopancreas R-cells suggested that the PNR is caused by an irreversible loss of the ability to restore lipid reserves depleted during initial starvation.

Beschreibung: This paper reviews the physical background of Energy Balance Climate Models and evaluates the use of Sellers' and North's model in simulating the present climate. The sensitivity of themodels - with updated empirical constants - is tested for use in the ice-age problem. In this connection the seasonal model of North and Coakley was extended to include a more realisticcontinent-ocean distribution. A simulation of the temperature field with a full-size Northern hemisphere continental ice sheet proved to be in fair agreement with palaeoclimatic proxy data.

Beschreibung: Nine holes were drilled with a submersible hydraulic drill into the slopes and reef flats of the Caubyna and Calituban reefs as well as of Olango Flat. The maximum depth of core penetration was 11 m. 14C ages showed that the Caubyan and Caltituban reefs were formed within the last 6,000 years. Corals settled on a pre-existing relief prallel to the island of Bohol, building a framework for other carbonate-producing organisms. The reef flat south of Olango has a different structure. Formation took place during a Pleistocene high sea level, e.g. 125,000 years ago.

Beschreibung: A comparative survey of several historical classifications of Annonaceae down to the subtribal level is given. The role of various key characters is briefly discussed. The present paper at the same time may be considered as an introductory paper to forthcoming publications of general studies on flower and fruit characters now being conducted at Utrecht.

Beschreibung: An unusual type of trichome is described for Anaxagorea (Annonaceae). On top of the stalk cell, extremely thinwalled cells form single, branched or stellate trichomes. The terminal cell(s) always end bluntly. When the thinwalled cells have been shed, the thick cuticle of the stalk cell remains as a cylindrical scar. Until now, this trichome type has not yet been found in other annonaceous genera. Our data contradict reports of other authors (Jovet-Ast 1942, Kramer 1969, Roth 1981) with regard to occurrence and structure of hairs in Anaxagorea.

Beschreibung: Recent taxonomic studies on the Lejeuneaceae subfamily Ptychanthoideae indicate that there are 59 species in 21 genera in Latin America. The ptychanthoid flora is very different from that of the Old World and has much fewer species but is slightly richer in endemic genera. About one third of the species are widespread neotropical elements, eleven species are transoceanicwide tropical, and the remaining species have more restricted distributions and belong to the endemic, Caribbean, Amazonian or Andean element. Data on sex distribution in the species indicate that bisexuality in Ptychanthoideae is much more common than previously assumed. The biogeography of the transoceanic species is briefly discussed.

Beschreibung: Served as a botanist with the Division of Botany, Lae, Papua New Guinea, from May, 1969, to March, 1975. Collections in NGF and LAE series from the West and East Sepik, Madang, Morobe, Western and Eastern Highlands, Western and Central Distr., Manus Island, New Britain and Bougainville. Left LAE in March, 1975, now at MEL after 8 years at NE.

Beschreibung: After the completion of his large treatment of the Acanthaceae for the Flore de l’Indo-Chine (1935) R. Benoist gave up any further study of the Acanthaceae of S.E. Asia. A very rich and almost unattended material of the family collected in Indochina during the following years accumulated in the Paris herbarium. By this time the well-known, Dutch acanthologist, C.E.B. Bremekamp, commenced studies in the Acanthaceae. For thirty years he published a wealth of papers on the subject until he in the late sixties due to failing eyesight was forced to give up his taxonomic activities. He has identified many of the early collections from Thailand made by Danish botanists and he published a few enumerations containing quite a number of new taxa. Simultaneously after the appearance of the Acanthaceae in the Flore Joan B. Imlay, Aberdeen, took up an intense study of the Thai representatives of the family. A fairly large paper with many new species and new combinations appeared in the Kew Bulletin (1939). A few years ago I learned from Mr. L.L. Forman, Kew, that she shortly afterwards went to South Africa and apparently ceased working in botany.

Beschreibung: Please submit your announcement to this Bulletin as early as possible! Several made here were received too late for interested readers to make use of. After the event please send a summary of the doings, and/or the Proceedings, if any. Settlement of aliens was the subject of a colloquium held at Paris by the Societe de Biogeographie in October 1982, entitled ”L’homme, facteur biogéographique’, now published in the C.R. des Séances de la Société, vol. 60 (1984) 1—72. Subjects were Buddleja at Paris, Acacia in the French Mediterranean, some marine algae, and reintroduction of menaced or vanished indigenous plant species in their original habitat for the benefit of conservation.

Beschreibung: The presence of psilocybin and its monomethyl analogue baeocystin is for the first time demonstrated in five taxa of the genus Inocybe, viz. I. coelestium, I. corydalina var. corydalina, I. corydalina var. erinaceomorpha, I. haemacta and I. aeruginascens. These taxa are characterized by a glaucous coloration of the stipe. A sixth taxon, I. calamistrata, which also has a blue-green stipe was found to be exempt of psilocybin and other methylated tryptamines. Negative results were also obtained for other Inocybes. Muscarin is absent in the psilocybincontaining species. However, no relation between taxonomic position and the presence of either compound seems to exist.

Beschreibung: S. officinale is a variable species. In the Netherlands three cytotypes occur: 2n = 24, 40, 48. The white-flowered diploid (2n = 24) is rare in Europe. The tetraploid cytotype (2n = 48) is represented by white- and purple-flowered plants in the Netherlands and by purple-flowered plants in Poland. In the Netherlands the diploids are very rare. In 8 localities, all occurring in the vicinity of the estate Oudegein (between the former villages Jutphaas en Vreeswijk, province of Utrecht) diploid plants were found. In two of these populations diploids and tetraploids grew intermingled. These mixed populations are now completely destroyed by reconstruction of roads and by town development, as are two populations of diploids. One diploid population is threatened and will probably disappear. The maintenance of the suitable habitat in the estate Oudegein is necessary for the preservation of the three remaining diploid populations of S. officinale in the Netherlands.

Beschreibung: During a checking of generic names of Malesian plants I asked the opinion of Mr. C.Jeffrey (Kew) about the status of the monotypic genus Guerreroia Merr., described from Luzon. In his opinion it deserves generic distinction. Fortunately Merrill’s description was accompanied by an excellent figure from which I had much earlier concluded that the species had already been described in Bidens, as B. tridentata Turcz., also from Luzon, which Merrill had erroneously reduced to Glossogyne tenuifolia Cass, in his Enumeration of Philippine Flowering Plants vol. 3 (1923)613.

Beschreibung: The correlation between sporoderm sculpture and life form of the sporophyte as postulated by Kramer (1977) is investigated for the fern genus Pyrrosia. This correlation is not found in Pyrrosia but may be present in other fern groups.

Beschreibung: After the general chapters, mainly based on literature and dealing with wood anatomy, characters of the leaf epidermis and foliar sclereids, embryology and chromosome numbers, phytochemistry, and characters of the fruit, the generic delimitation of subfamily Magnolioideae is discussed. Paramichelia Hu and Tsoongiodendron Chun are reduced to Michelia Linné; Talauma Juss., Aromadendron Blume, Alcimandra Dandy, Dugandiodendron Lozano and Manglietiastrum Law are reduced to Magnolia Linné. Parakmeria omeiensis Cheng & Hu is renamed Magnolia omeiensis, Parakmeria yunnanensis Cheng & Hu is renamed Magnolia yunnanensis, Manglietiastrum sinicum Law is renamed Magnolia sinicum, and Alcimandra cathcartii Dandy is renamed Magnolia cathcartii Manglietia singalanensis Agostini is reduced to M. glauca var. sumatrana. Elmerrillia mollis Dandy and E. papuana Dandy are reduced to Elmerrillia tsiampacca (Linné) Dandy, the former is named subsp. mollis (Dandy) Noot. and of the latter var. glaberrima is renamed E. tsiampacca var. glaberrima (Dandy) Noot. Michelia arfakiana Agostini is reduced to Elmerrillia tsiampacca var. tsiampacca and Michelia sumatrae Dandy is renamed M. salicifolia Agostini. Newly described is Michelia koordersiana Noot. and keys are given to the genera, subgenera and sections.

Beschreibung: Up to now, no intercalary males of Cylindroiulus nitidus (Verhoeff) had been found, neither in Britain, nor in S.W. Germany. Hand sampling led the author to the discovery of three intercalary males in 1983 at Milldale (Derbyshire, Great Britain) on the one hand and one at Mettlach (Saarland, W. Germany) on the other. British adult males have been reared in field plots at Milldale and Baulme-la-Roche (France), Baulme-la-Roche males at Milldale and German ones at St. Ingbert (Saarland). The results of these experiences are given. It seems that the frequency of intercalaries depends on the years. It is suggested that in C. nitidus intercalaries are a resistance form which may have appeared during evolution. The adult to adult succession could be possible only under good environmental conditions, intercalaries becoming then useless. It is stressed that periodomorphosis and the adult to adult succession are both of great adaptive value compensating for some disadvantages of neoteny.

Beschreibung: On 31 May 1938 our predecessor professor Pulle delivered an address on the ”stocktaking of the heritage of our forefathers” on the occasion of the opening of the enlarged and reorganized Laboratory of special Botany and Plant Geography” of the University of Utrecht. The ”renewal” had been radical: a totally new herbarium building had been built in the southern-most part of the old Botanical Garden at the Lange Nieuwstraat in Utrecht. Pulle’s address still merits reading. The printed version, in Dutch, was handed out after the delivery of the address. In case Pulle actually read the complete text, this must have taken some ninety minutes. I shall not take that long and I also do not plan to hand you a printed version at the end of the ceremony. Even so I would like to use this opportunity to tell you something about this ”heritage”, and about the herbarium and its use as well as about the history of our institution. The use of the term ”stocktaking of our forefathers’ heritage” goes back to the Dutch agronomist and botanist Willem Frederik van Eeden, who, in his capacity as director of our first ”Colonial Museum” wrote a paper in 1896 in the ”Indische Mercuur”: ”What are the goals of science in the Netherlands? Contributing its mite towards the general structure of science; the diligent research with respect to our incompletely known colonies; the stocktaking .....”. W.F. van Eeden was also founder of what was later called the ”Van Eeden-fonds for botanical research in Suriname and the West-Indian islands”. Thanks to this fund our institute could publish its Flora of Suriname and organize numerous exploratory activities in those territories.
