    The species of Alangium section Rhytidandra (Alangiaceae) (2017)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (2212-1676) vol.62 (2017) p.75
    Details
    Publication Date: 2017-04-21
    Description: Alangium sect. Rhytidandra is confined to SE Asia, the Pacific and East Australia, and contains 13 species. Five species, viz. Alangium brassii, A. glabrum, A. gracile, A. guadalcanalense, and A. velutinum are described as new, whereas A. villosum subsp. solomonense is raised to specific rank: A. solomonense. Subspecies tomentosum formerly in A. villosum is transferred to another species and has become A. polyosmoides subsp. tomentosum. Finally Iodes ferruginea, described in Icacinaceae appeared to belong in Alangiaceae, and as the name ferruginea was occupied in Alangium it is changed into A. strigosum, nom. nov. A key to the species is presented, and the concerned taxa are enumerated, referenced, described, and two are figured.

    Details
    Publication Date: 2015-04-20
    Description: Mostly climbing herbs or lianas with axillary tendrils, rarely erect herbs, shrubs or small trees, glabrous or hairy, in Mal. not spiny. Branching usually by a supraaxillary serial bud. Leaves (mostly) spirally arranged, simple or compound, pinninerved or palminerved, entire or lobed; petiole or blade-base often with 1-many glands, and often glands on margin and lower surface of the blade. Stipules present. Inflorescences essentially axillary, cymose, sessile or peduncled, 1-many-flowered, ending in (a) tendril (s) or not. Bracts and bracteoles mostly small. Flowers often stiped, articulate to the pedicel, actinomorphic, bisexual or functionally unisexual (either with staminodes or a vestigial ovary, and then plants mostly dioecious) or polygamous. Perianth mostly 2-seriate, mostly persistent, the segments free or partially connate (Adenia p.p.), inserted on the rim of the saucer- or cup-shaped or tubiform hypanthium. Sepals (4—)5( 6), imbricate. Petals (4-)5(-6), mostly imbricate. Corona inserted on the hypanthium, mostly a complicated structure, composed either of filaments, hairs, or appendages, or membranous, annular, or composed of scales (disk), or in addition with ‘septa’ (Adenia p.p.), rarely corona absent (Adenia p.p.). Stamens 4-10, inserted mostly at the base of the hypanthium, or on an androgynophore (mostly hypogynous), (mostly) opposite the sepals; filaments free or partially connate into a tube; anthers 2-celled, longitudinally dehiscent, sometimes apiculate. Ovary superior, subsessile or on a gynophore or androgynophore, 1-celled, 3(-5)-carpellate; placentas 3(-5), parietal; ovules many, anatropous; integuments 2; styles 1 or 3 (-5), very short to distinct, sometimes partially connate; stigmas ± globose, or capitate, or papillate, or much divided. Fruit a loculicidally 3(-5)-valved capsule, or berry-like. Seeds mostly numerous, mostly compressed, often beaked, enveloped by a (membranous or juicy) aril; funicles often distinct; testa crustaceous (coriaceous), mostly striate, reticulate or pitted; endosperm (copious) horny; embryo straight; cotyledons foliaceous. Cf. HARMS in E. & P. Nat. Pfl. Fam. ed. 2, 21 (1925) 470-507. Distribution. About 10 genera and 500 spp., almost entirely confined to the tropics: in America c. 350 spp. (mainly Passiflora, a few species in Dilkea, Mitostemma, Tetrastylis), in Africa (incl. Madagascar) c. 110 spp. (mainly Adenia c. 80 spp., Tryphostemma c. 20 spp., Deidamia, incl. Efulensia, Crossostemma, c. 6 spp., incl. Schlechterina, 2 spp.), in Asia and Australia c. 40 spp. (Passiflora c. 20 spp., Adenia 14 spp., Hollrungia 1 sp., Tetrapathaea 1 sp. in New Zealand).

    Myristicaceae (2000)
    In:  Flora Malesiana - Series 1, Spermatophyta (1872-924X) vol.14 (2000) nr.1 p.1
    Details
    Publication Date: 2015-04-20
    Description: A pantropical family of trees, in Malesia represented by six genera: Endocomia (4 species), Gymnacranthera (6), Horsfieldia (97), Knema (75, only one species in New Guinea), Myristica (152, of which the majority endemic to New Guinea), and Paramyristica (1, Papua New Guinea). Altogether there are 335 species of the family in the Malesian area. Some species are of economic importance, for instance Myristica fragrans, nutmeg. The general part consists of 28 pages and also includes paragraphs on vegetative anatomy by P. Baas & J. Koster, on palynology by R.W.J.M. van der Ham, and on phytochemistry and chemotaxonomy by R. Hegnauer. Myristicaceae are dioecious. In addition to the general keys, mainly based on male specimens, also regional keys are given for the larger genera Horsfieldia, Knema, and Myristica, based on female (fruiting) specimens. For each species full references, synonymy, keys to infraspecific taxa, diagnostic descriptions, field-notes, distribution, and annotations regarding relationships or differences with resembling species are presented. Genera and species are arranged alphabetically. This treatment is illustrated with 94 line drawings (many full-page), 6 maps, and 4 pages with colour photographs* (inserted after p. 8).

    Najadaceae (1960)
    In:  Flora Malesiana - Series 1, Spermatophyta (0374-7778) vol.6 (1960) nr.1 p.157
    Details
    Publication Date: 2015-04-20
    Description: Within the Helobieae there has been a great deal of controversial opinion about the evaluation of the genera belonging to the Potamogetonaceae, among which Najas finds by almost unanimous opinion its closest relatives. Generally Najas has been accepted to represent a separate monotypic family on account of the basal ovule and the structure of the anther (with a thin, tight, 2-lipped envelope and apically escaping pollen). The closest allied genus among Potamogetonaceae seems to be Zannichellia, which is by HUTCHINSON (1934) accepted as a separate family, Zannichelliaceae, put together with Najadaceae in his order Najadales. Within the Helobieae some authors accept the structure of Najadaceae as primitive, notably CAMPBELL (1897) and RENDLE (1930), but others find it a derived, advanced state within the order, cf. HUTCHINSON (1934) and LAWRENCE (1951).

    Supplementary data on Malesian Knema (Myristicaceae) including three new taxa (1981)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.27 (1981) nr.1 p.223
    Details
    Publication Date: 2015-03-06
    Description: Among the collections of Knema acquired by the Rijksherbarium since the publication of my new account of the genus Knema, in Blumea 25, 1979: 321 — 478, a few specimens caused problems with the identification, and at closer examination these yielded facts of interest which are published here. Some specimens represented stages not yet known, for instance fruits, or male flowers, while other specimens meant a significant range extension of the species. Two new species and one new subspecies are described. For easy reference, the sequence and numbers of the species presently treated correspond with the numbers as used in the account of 1979. The new species bear the number of the species after which they appear in the general key of 1979, with the addition ‘-bis’.

    Description: This project of the Royal Botanic Garden Edinburgh aims to provide regional manuals and on-line identification computer programs to the timber species of Dipterocarpaceae. The Singapore manual is a first trial, later editions should include other islands in the Malay Archipelago. The possibility is also offered to have tailor-made manuals for specific regions against cost price. Many data have been gathered, especially vegetative characters one can readily observe while standing underneath these enormous trees. In this respect the database will be very useful, because due to the very irregular flowering of the Dipterocarpaceae, flowers and fruits are usually unavailable, and even if they are present, they are found high in the tree.

    Review (1994)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.39 (1994) nr.1/2 p.138
    Details
    Publication Date: 2015-03-06
    Description: In this volume the author concentrates on the comparative study of tropical flowers. He gives a practical approach (see Introduction, page 3) to recognize tropical flowers at three levels: a) Organization (‘Bauplan’), with emphasis on history and macroevolution (see Chapter 2); b) Construction (‘Gestalt’), i.e. architecture (see Chapter 3); and c) Mode, with emphasis on ecology and microevolution (see Chapters 4 & 5). Its scope is the understanding or biological interpretation of characters and character variation of flowers for the phylogenetic reconstruction of the angiosperms at these levels. The author claims that knowledge of the phylogenetic history and of the interactions between animals and plants may be of vital importance for the evaluation of conservation actions and that the modem threats to biodiversity urges more and better knowledge of the biology of flowers in the widest sense. In Chapters 2-7 an enormous number of facts about flowers have been brought together, most from literature but also from original sources, providing a unique insight into the (reproductive) morphology, biology and evolution of flowers, as much as possible indicating the major presumed evolutionary trends.
