    Description: The Crepidorhopalon whytei (Linderniaceae) species complex is revised using morphological analyses. Based primarily on variations in indumentum, floral morphology, corolla colour and seed morphology, four species are formally recognised within this group in eastern Africa. Crepidorhopalon whytei s.str. is widespread in the highlands of eastern Africa, extending from South Sudan and Ethiopia in the north through to western Tanzania in the south. A new combination in Crepidorhopalon is made for Lindernia flava (= C. flavus), which is confined to the Manica Highlands of the Mozambique-Zimbabwe border. Two new species are described, C. namuliensis which is known only from Mt Namuli in northern Mozambique and C. kwaleensis which is known only from the coastal lowlands of southeast Kenya. A fifth, imperfectly known species is documented from the Nguru Mountains of Tanzania where it is so far known from a single collection. Three names are lectotypified. The habitat requirements and distribution are documented and the extinction risk is assessed for each species. Crepidorhopalon flavus is assessed as globally Vulnerable and C. kwaleensis as globally Endangered, while C. namuliensis and C. whytei are currently considered to be of Least Concern, although the latter is declining markedly in parts of its range. The botanical importance of the key sites for the newly recognised taxa is discussed.

    Ficus pongumphaii (Moraceae), a new species from Thailand, compared with the ambiguous species F. talbotii (2019)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64, pp. 108-114
    Details
    Publication Date: 2024-06-26
    Description: A deciduous shrub previously included in Ficus talbotii for many years, is now regarded as a new species, Ficus pongumphaii. It is morphologically distinct from F. talbotii with as typical characters the densely brown pubescent to tomentose or villous on leafy twig; the elliptic, suborbicular to obovate leaf blades that are brown tomentellous on the upper surface and brown floccose tomentose to villous underneath; the pedunculate figs are obovate, brown floccose or villous outside and have internal hairs. The leaf anatomy shows a multiple epidermis on both surfaces; enlarged lithocysts on both sides of the lamina, which are more abundant adaxially and with very few abaxially. The species, endemic to Thailand, is named after the great Thai dendrologist, Associate Professor Somnuek Pongumphai.

    The Euploca baclei complex (Boraginaceae subfam. Heliotropioideae) (2019)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64, pp. 92-95
    Details
    Publication Date: 2024-06-25
    Description: In order to recognise both taxa previously regarded as varieties of Heliotropium baclei, nowadays classified in Euploca, a new combination is necessary. As the two varieties are clearly separable in terms of morphology and biogeography, we propose to raise these varieties to the species level, for which the new combination Euploca katangensis needs to be created. Moreover, we propose the new combination Euploca madagascariensis for Heliotropium madagascariense, a species from Madagascar considered by some as conspecific with H. baclei, but treated here as distinct. For these three species with beaked fruits, constituting the ‘Euploca baclei complex’, a key and a distribution map, based on revised herbarium specimens, is given. Two additional combinations, Euploca bullockii and Euploca sessilistigma are made to complete the transfer of tropical African Heliotropium species that belong in Euploca.

    A taxonomic revision of Phyllanthus subgenus Macraea (Phyllanthaceae) (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 3, pp. 231-252
    Details
    Publication Date: 2024-06-25
    Description: Within the morphologically diverse pantropical genus Phyllanthus, many subgenera, sections and subsections are recognized. While most taxonomic revisions often focus on local floras, closely related and often resembling species are not always treated in full. Subgenus Macraea is here revised for the first time over its whole distribution, including an identification key and descriptions of its species with distributions, ecology, uses and vernacular names. The currently acknowledged varieties of Phyllanthus distichus are rejected due to inadequate morphological differences. Phyllanthus panayensis is synonymized with P. lancifolius. Phyllanthus alpestris has now become a variety of P. glaucophyllus because of the resemblance in morphology and distribution. The species complex around Phyllanthus virgatus remains taxonomically difficult, but Phyllanthus virgatus var. gardnerianus and Phyllanthus virgatus var. hirtellus are here recognized on the species level as P. gardnerianus, stat nov. and P. tararae, stat & nom. nov. A new species from the Philippines, Phyllanthus ridsdalei, is described

    Taxonomic revision and molecular phylogeny of Flemingia subgenus Rhynchosioides (Leguminosae) (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 3, pp. 253-271
    Details
    Publication Date: 2024-06-24
    Description: A taxonomic revision of Flemingia subg. Rhynchosioides based on morphology and molecular information (matK and ITS) is presented. The subgenus comprises six herbaceous taxa (F. gracilis, F. mukerjeeana, F. nilgheriensis, F. rollae, F. tuberosa and F. vestita). All species except F. vestita are endemic to India. Morphological evidence and molecular phylogeny revealed that the subgenus is monophyletic. Nevertheless, the systematic position of F. tuberosa remains unclear on account of its unique ecology and inflorescence. A new species, F. mukerjeeana, is described and four binomials, namely F. gracilis, F. nilgheriensis, F. tuberosa and F. vestita have been lectotypified. Furthermore, all species have been described, illustrated and their ecology discussed. A taxonomic key including the recently described species from Thailand, F. sirindhorniae, is also provided for easy identification

    Details
    Publication Date: 2024-06-23
    Description: An identification key to all the reported species of Hedyotis-Oldenlandia group (Hedyotis, Oldenlandia, Exallage, Leptopetalum, Scleromitrion and Debia) in Andaman & Nicobar Islands is presented with one new species, Oldenlandia smita-crishnae, described from Saddle Peak forests of North Andaman, India. It shares some characters with Oldenlandia herbacea, O. corymbosa and O. pseudocorymbosa. However, it is remarkable for its abaxially puberulous leaves, divaricate stipules, ellipsoid to obovoid hypanthium, pink-striped corolla lobes and 20–30-seeded, inserted capsule. Furthermore, a new combination in Exallage is proposed and lectotypes for Spermacoce cristata, S. costata, Hedyotis vestita and Oldenlandia stocksii are designated.

    Recircumscription and revision of the genus Vanoverberghia (Zingiberaceae) (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 2, pp. 140-157
    Details
    Publication Date: 2024-06-23
    Description: The genus Vanoverberghia currently includes three species namely V. sepulchrei and V. rubrobracteata from the Philippines and V. sasakiana from Taiwan. New material targeting the Alpinia eubractea clade of the tribe Alpinieae was used to test the monophyly of Vanoverberghia.Acombined analysis of the ITS and trnK/matK regions reveals that these three species form a strongly supported monophyletic clade with Alpinia diversifolia and Alpinia vanoverberghii. The morphological descriptions of all species were updated after examining recent collections and comparing with types and protologues. The original description of A. diversifolia did not include information on the flowers which are described here. The morphology of A. diversifolia and A. vanoverberghii is for most parts in accordance with the previous perception of the genus but a few characters are added and a recircumscription of Vanoverberghia is subsequently provided here. Vanoverberghia diversifolia is reinstated and A. vanoverberghii is combined in Vanoverberghia. Furthermore, collections from northern Luzon documents the presence of V. sasakiana and all species of Vanoverberghia thus occur in the Philippines. A key to the five species is provided including a comprehensive taxonomic revision and designation of three lectotypes.
