    Publication Date: 2015-05-08
    Description: In Juni, Juli en September 1955 werden aan de oever van het gedeelte van de Maas, dat door het Juliana-kanaal is afgesneden, resp. door een I.V.O.N.-excursie, de excursie van de Commissie voor het Floristisch Onderzoek uit de K.N.B.V. en ondergetekenden een opvallend groot aantal adventieven verzameld, waarvan een 10-tal nog niet eerder in Nederland was aangetroffen. Door de zeer lage waterstand hadden deze adventieven zich volop kunnen ontwikkelen op plaatsen, waar door het graven van grint vele kuilen waren ontstaan en op de zand- en rolsteenstrandjes aan de luwe zijde van de bochten van de rivier. De zaden en vruchten zijn wel zeker door de Maas aangevoerd van hogerop in het stroomgebied gelegen fabrieken en losplaatsen; de wolfabrieken aan de Vesdre hebben waarschijnlijk een belangrijk aandeel in deze aanvoer gehad. De gevonden soorten zijn voor een groot deel oorspronkelijk afkomstig uit het Middellandse Zee – gebied. Hieronder volgt eerst een lijst van de vindplaatsen en data, daaronder de zo goed als volledige lijst van de aangetroffen soorten. De nummers achter de soorten geven de vindplaatsen aan; de namen der voor de eerste maal in Nederland gevonden taxa zijn onderstreept. Vindplaatsen: (1) Maasoever tussen Obbicht en Grevenbicht; 7-VI, 20-VII, 23-IX-1955. (2) idem bij Meers, gem. Elsloo; 9-VI, 21-VII, 23-IX-1955. (3) idem ten N. van Grevenbicht; 8-VI-1955. (4) idem tegenover Maaseyck; 22-VII-1955. (5) idem bij Uhe en Laak; 24-IX-1955.

    Description: Het Instituut voor het Vegetatie-onderzoek van Nederland (I.V.O.N.) werd opgericht in 1930 en is thans gevestigd in het Rijksherbarium, Nonnensteeg 1 , Leiden, Het stelt zich o.a. ten doel om door stelselmatige inventarisatie een overzicht te verkrijgen van de verspreiding der in Nederland voorkomende Pteridophyta en Spermatophyta. Reeds in 1902 werd door de heren Dr. J.W.C. Goethart en W. J. Jongmans, destijds resp. conservator en assistent aan het Rijksherbarium, een aanvang gemaakt motdit biogoo grafische onderzoek. In de jaren daarna werd het met medewerking van een aantal Nederlandse floristen voortgezet, waarna men wegens de toenemende betekenis van het werk en met medewerking van de heren Goethart en Jongmans in 1930 kwam tot de oprichting van het I.V.O.N. Bij de inventarisatie werd tot voor enige jaren – het oorspronkelijke werk werd nl. in 1949 afgesloten – gebruik gemaakt van de Topografische kaart van Nederland, schaal 1 : 50.000, welke ten behoeve van het onderzoek door verticale en horizontale lijnen in vakken was verdeeld van 1045 bij 1250 m. Deze vakken, kwartierhokken genaamd, vormden de eenheden van de inventarisatie. Per kwartierhok werd nl. genoteerd welke planten daarin werden waargenomen, hetgeen gebeurde op excursies in verschillende jaargetijden, waardoor een zo volledig mogelijk overzicht der voorkomende soorten werd bereikt. De zo verkregen gegevens werden vervolgens soort voor soort in albums overgebracht, waarbij ieder album betrekking heeft op een der 62 bladen van de Topografische kaart 1 : 50.000. Tenslotte was het mogelijk om de in de albums vervatte gegevens op een kaart van Nederland te noteren, zodat een overzicht werd verkregen van de verspreiding van de betreffende soorten over het gehele land. Als resultaat werd een serie z.g. Plantenkaartjes van Nederland uitgegeven. Deze kaartjes geven, dank zij de grote volledigheid, die bij de inventarisatie bereikt werd, een betrouwbaar beeld van de verspreiding der plantensoorten. Het ligt in de bedoeling om de publicatie van deze serie Plantenkaartjes zo lang voort te zetten tot een beeld van de verspreiding van alle Nederlandse Pteridophyta en Spermatophyta verkregen zal zijn. In de nog te verschijnen kaartjes zullen daarbij alle gegevens tot en met 1949 verwerkt worden.

    In:  Flora Malesiana - Series 1, Spermatophyta (0374-7778) vol.4 (1948) nr.1 p.388
    Publication Date: 2015-04-20
    Description: Herbs or shrubs, sometimes parasitic, usually with twining stems, occasionally prostrate or creeping, or erect, very rarely trees, often with milky juice. Leaves mostly spirally arranged, in parasitic species absent or nearly so, usually petioled; petiole sometimes with extra-floral nectaries. Stipules absent, pseudostipules (leaves of axillary shoot) rarely present. Inflorescences mostly cymose, one- to many-flowered, with mostly opposite or subopposite bracts at the base of the cymes or under the solitary flowers; rarely racemose. Flowers generally hermaphrodite, actinomorphic, rarely slightly zygomorphic, usually 5-merous, rarely 4-merous, various in size and colour, often showy. Sepals usually free, imbricate, with quincuncial aestivation, often persistent, sometimes accrescent in fruit. Corolla sympetalous, of various shapes, often funnel-shaped or campanulate, more rarely rotate, salver-shaped or urceolate; the limb nearly entire or more or less deeply lobed, often contorted-plicate in bud, or valvate or induplicate-valvate. Stamens isomerous, alternating with the corolla-lobes, adnate to the corolla, with usually slender, often filiform filaments and introrse or laterally and longitudinally dehiscing anthers. Pollen smooth or spinulose. Disk mostly present, annular or cupular. Ovary superior, mostly of 2 carpels, 2- or 1-celled, sometimes 4-celled by development of accessory partitions, rarely of 3 carpels and 3-celled; ovules 2 in each carpel, sessile, erect, anatropous. Style 1, often filiform, simple or forked, or 2 free styles, rarely very short or absent. Stigma entire or 2-lobed, rarely 3-lobed, or stigmas 2-4, of various shape, globular or ellipsoid to filiform, sometimes applanate, rarely peltate, kidney-shaped, conical or funnel-shaped. Fruit a capsule dehiscing by valves or circumscissile or irregularly dehiscing, rarely a berry or nut-like. Seeds as many as ovules or fewer; endosperm cartilaginous; cotyledons generally folded, sometimes obscure or absent. Distr. Ca 55 genera, with ca 1650 spp., widely distributed in the tropical, subtropical and temperate regions of both hemispheres; the greater part of the species in the tropics and subtropics of America and Asia. The larger genera Cuscuta (ca 165 spp.), Convolvulus (ca 250 spp.) and Ipomoea (ca 500 spp.) nearly throughout the range of the family but Convolvulus more in the temperate parts and Ipomoea more in the tropics and subtropics. Other large genera as Evolvulus (ca 100 spp.) and Jacquemontia (ca 120 spp.) nearly confined to America. Argyreia (ca 90 spp.) confined to tropical Asia. Malaysia, and a single sp. in Australia, and Merremia (ca 80 spp.) circumtropical. Several monotypic or small genera in E. Africa, Madagascar, and Australia.

    Publication Date: 2015-03-06
    Description: This is the second contribution to a series of papers dealing with the Convolvulaceae of Malaysia (Malay Peninsula and Archipelago, Philippine Islands and New Guinea). The genera worked out here belong to the tribe Convolvuleae; they are numbered VIII—XV. Genus VII, Erycibe, belonging to the Erycibeae shall be treated afterwards in a special monograph. With regard to the geographic arrangement of the specimens mentioned, some alterations had to be introduced due to the new limitation of the residencies in the island of Java. The names and limits of these residencies are now brought into line with the data of the ”Atlas van Tropisch Nederland“ ²).

    Publication Date: 2015-03-06
    Description: This is the first contribution to a series of papers dealing with the Convolvulaceae of Malaysia (Malay Peninsula and Archipelago, Philippines and New Guinea). As far as possible the contributions will be published in accordance with the systematical arrangement of the genera. For a survey on this arrangement I refer to HAULIER'S fundamental work on this matter published in 1893 in the 16th volume of ENOLER'S Botanische Jahrbücher, entitled: ”Versuch einer natürlichen Gliederung der Convolvulaceen auf morphologischer und anatomischer Grundlage“. After all genera will have been published, a determination key will be added, based on the genera of the area under consideration, in which I hope to take especially account of the characters of the Malaysian species. Meanwhile the key published by HAULIER in the above mentioned paper can be provisionally used. On account of the structure of the pollen grains the Convolvulaceae as a whole can be subdivided, as has been proposed by HAULIER, into two groups, viz. the Psiloconiae with smooth pollen grains and the Echinoconiae with spinose ones. The former of these groups contains seven tribes, viz. 1. Cuscuteae, 2. Wilsonieae (not in Malaysia), 3. Dichondreae, 4. Dicranostyleae, 5. Poraneae, 6. Erycibeae and 7. Convolvuleae. Of the six genera worked out here, Cuscuta belongs to the Cuscuteae, Dichondra to the Dichondreae, Evolvulus, Bonamia and Neuropeltis to the Dicranostyleae and Porana to the Poraneae. For the limitation and description of the tribes see HALLIER l.c. and in ENGLER’S Botanische Jahrbücher, Vol. XVIII, 1894, p. 92, under Prevostea.

    Description: Hallier ²) subdivided the Convolvulaceae into two groups, viz. the Psiloconiae, with smooth pollen grains, and the Echinoconiae with spinose ones. The genera of the Psiloconiae occurring in Malaysia have been dealt with in parts I and II of the present paper, with exception of the genus Erycibe, which shall be treated in a special monograph. The group of Echinoconiae contains two tribes, viz. 1. Ipomoeeae and 2. Argyreieae, both represented in Malaysia. The genus Ipomoea belongs to the Ipomoeeae.

    Description: The publication of the supplement 1 of the well known and essential reference work of “A Bibliography of Eastern Asiatic Botany” is very welcome. It is a continuation of the original work, which closed with 1936, and extends through 1958. It covers the botanical literature on eastern Asia, as indicated by the title, which comprises China, Japan, Korea, Ryukyu, Mongolia and Soviet eastern Asia, as well as the major published papers appertaining to adjacent areas. It has been prepared on essentially the same pattern as the original volume while the subject index has been treated perhaps in a more thorough manner. The volume contains over 11,000 extensively and carefully annotated entries occupying 414 pages. The work is in English but the titles, papers and author names in oriental characters are fully cited, which is an improvement as compared with the original volume. It includes now the original Chinese, Japanese and Korean titles and author names as published in oriental characters as well as translations or transliterations of them. In addition, the supplement fortunately covers the extensive Russian literature, nearly 1600 entries, on Soviet eastern Asia. All Russian titles are transliterated into Roman letters and are also translated. All these improvements make this bibliography more complete than the original volume and extend its usefulness.
