    Alseodaphnopsis (Lauraceae) revisited (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 2, pp. 186-189
    Details
    Publikationsdatum: 2024-07-03
    Beschreibung: Generic delimitations among the Asian members of the Persea group, including the recently described genus Alseodaphnopsis, are discussed. These genera, with the exception of Alseodaphnopsis, are characterized by reproductive characters. A study of flowers of Alseodaphnopsis species found that Alseodaphnopsis species have unisexual flowers and that Alseodaphnopsis is better defined by its unisexual flowers than by vegetative characters. This is the first report of the presence of unisexual flowers in any member of the Persea group.

    A new species and a synopsis of the Hedyotis-Oldenlandia group (Rubiaceae: Spermacoceae) in Andaman & Nicobar Islands, India (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 3, pp. 225-230
    Details
    Publikationsdatum: 2024-07-03
    Beschreibung: 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.

    A revision of the Crepidorhopalon whytei complex (Linderniaceae) in eastern Africa (2019)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64 no. 2, pp. 165-176
    Details
    Publikationsdatum: 2024-07-03
    Beschreibung: 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.

    Revision of the Neotropical genus Desmopsis (Annonaceae) (2018)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 63, pp. 67-86
    Details
    Publikationsdatum: 2024-07-03
    Beschreibung: A taxonomic revision of the genus Desmopsis is presented. Within the genus Desmopsis 25 species are recognized, 9 of which are new, with one new combination. Distinguishing morphological characteristics are discussed, and a dichotomous key to all species is given. The species treatments include descriptions, full synonymy, geographical and ecological notes, vernacular names, and taxonomic notes. Distribution maps are presented of all species, and a complete identification list of exsiccatae examined is included.

    Taxonomy and evolutionary history of the neotropical fern genus Salpichlaena (Blechnaceae) (2019)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 64, pp. 1-22
    Details
    Publikationsdatum: 2024-07-03
    Beschreibung: Salpichlaena is a distinctive fern genus characterised by 2-pinnate climbing fronds with indeterminate growth. The number of species in the genus has been a matter of debate. Taxonomic studies are made difficult by within-frond variability in pinna morphology and size, and by herbarium material being incomplete. We systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena and 11 outgroup specimens. DNA sequences included plastid genes (rbcL, rpoC1 and rps4), intergenic spacers (rps4-trnS, trnHpsbA and trnG-trnR) and a nuclear gene (pgiC). Phylogenetic analyses based on the plastid markers divided the samples into six major clades. We recognise the three deepest clades as distinct species (S. hookeriana, S. papyrus sp. nov. and S. volubilis), and each of the four shallower clades as a subspecies of S. volubilis. Furthermore, we suggest that a group of specimens, placed into different clades in the plastid and nuclear trees and showing mixed morphological characters, represent a fourth species of hybrid origin (S. hybrida sp. nov.). The most important diagnostic characters are: degree of lamina reduction in fertile pinnules; pinna/pinnule apex incisions, pinna/pinnule margin thickness and lamina texture in sterile pinna/pinnules; presence or absence of foliar buds; shape of scales; and the appearance of the abaxial surface of the lamina (uniform or with stomata on small white protuberances). Each of the four species can be identified by several diagnostic characters, and their geographical ranges are broad and partly overlapping. In contrast, the subspecies are mostly allopatric and their morphological limits are diffuse.
