    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.

    Taxonomy of Alangium section Conostigma (Alangiaceae) (2017)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (2212-1676) vol.62 (2017) p.29
    Details
    Publication Date: 2017-02-17
    Description: Alangium Lam. sect. Conostigma Bloemb. is largely confined to the Malesian area and contains 19 species. By using the characters as found in the original species-descriptions, and with emphasizing the nature of the indument of the leaf bud, the confusingly variable Alangium javanicum s.l.-complex could be dismantled for a great part. Four new species: A. ledermannii, A. pallens, A. plumbeum, and A. subcordatum, and two new varieties: A. meyeri var. macilentum and A. ebenaceum var. insignis are recognised. Two taxa are raised to specific status: A. nobile subsp. denudatum to A. denudatum and A. javanicum var. minahassicum to A. minahassicum. A key to the species is presented, and the concerned taxa are enumerated, referenced, described and some are figured.

    Publication Date: 2015-03-06
    Description: Anthocleista potalioides, a new narrowly endemic species of the Chaillu Mountains in Gabon is described and illustrated. Its taxonomic position among the known African species is discussed. It stands apart by a small 8-merous corolla and a 2-locular ovary. Remarks on the affinities of the African genus Anthocleista and Potalia from tropical America are presented.

    Revision of the African genus Heckeldora (Meliaceae) (2007)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.52 (2007) nr.1 p.179

    Publication Date: 2015-03-06
    Description: The African genus Heckeldora (Meliaceae) is revised. Contrary to earlier views the widespread and variable H. staudtii is shown to consist of four distinct entities, each worthy of specific status. Heckeldora zenkeri is therefore re-instated and two other species, originally described in the much larger genus Guarea, and formerly also considered conspecific with H. staudtii, are resurrected and formally transferred to Heckeldora. In addition, two new species, H. jongkindii J.J. de Wilde from Liberia and H. trifoliolata J.J. de Wilde from Gabon are recognized and described. Heckeldora mangenotiana is transferred to Guarea and the new combination made. A key to the six Heckeldora species now recognized is provided and maps of their distribution are presented.
