    Four new Curcuma species (Zingiberaceae) from Thailand (2021)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 3, pp. 244-253
    Details
    Publication Date: 2024-06-28
    Description: Four new Curcuma species (Zingiberaceae) from Thailand are described here. Curcuma fimbriata, C. micrantha and C. spathulata belong to C. subg. Hitcheniopsis, while C. globulifera belongs to the nominal C. subg. Curcuma. Each species is compared to the morphologically closest species and detailed descriptions, colour plates and information on their distribution, ecology, phenology and uses are provided. A preliminary IUCN conservation assessment of each of these species is proposed.

    A synoptic revision of the golden glories, genus Decalobanthus Convolvulaceae (2022)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 67 no. 1, pp. 37-70
    Details
    Publication Date: 2024-06-27
    Description: Eighteen species of Decalobanthus are recognized in this concise revision of the genus. Two new combinations are made and one new name is proposed to accommodate a change in rank. The genus is centered in SoutheastAsia and Malesia, with outlier species in the tropical Pacific and one species that reaches the Neotropics; a single wide-ranging species extends from eastern Tropical Africa and Madagascar in the west to the Hawaiian Islands in the east. Each species is provided with a diagnosis, summary of the species’ ecology, compiled vernacular names, and uses. Distributions are mapped based on herbarium voucher specimens. Where appropriate, typifications and nomenclatural problems are explained and comments on morphological variation and the need for further study are highlighted. Selected species are illustrated with colour photos of living plants. An index of numbered collections examined is provided to aid in specimen identification and herbarium curation.

    Two new species of Hanguana (Hanguanaceae) from Kalimantan, Indonesia (2021)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 66 no. 1, pp. 101-105
    Details
    Publication Date: 2024-06-26
    Description: Two new Hanguana species from Kalimantan, Indonesian Borneo, are described here. Hanguana karimatae from Karimata Island, West Kalimantan province, is characterised by a stout habit, prominently oblique yellow fruits with raised stigma and 1- or 2-seeded fruits. Hanguana nana from Central Kalimantan province is the smallest species in the genus with the stem entirely covered by leaves, deflexed barely branched infructescences with only a few fruits, each with a single bowl-shaped seed with a large and incurved appendage. These are the first descriptions of new Hanguana species from Kalimantan (Indonesian Borneo). Colour plates as well as notes on distribution, ecology, habitat and conservation status are provided.

    Maesa brevipedicellata (Primulaceae), a new species from Papua New Guinea (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 83-85
    Details
    Publication Date: 2024-06-24
    Description: Maesa brevipedicellata, a new species of Maesa (Primulaceae-Maesoideae) from Papua New Guinea, is described and illustrated based on herbarium specimen observations. The collections of this species resemble M. rufovillosa and were previously determined as that species. Maesa brevipedicellata is unique with its selfsupporting habit, hispid hairs throughout and paniculate inflorescences with very short pedicels. This new species mainly differs from M. rufovillosa by the habit (tree/shrub in M. brevipedicellata vs climber in M. rufovillosa) and the inflorescence structure (panicles in M. brevipedicellata vs simple racemes in M. rufovillosa).

    A new and unusual species of Dichaea (Orchidaceae: Zygopetalinae) from Costa Rica (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 61-64
    Details
    Publication Date: 2024-06-24
    Description: A new and florally unusual species of the genus Dichaea is described and illustrated from Costa Rica, where it is apparently endemic, and its relationships are discussed. Dichaea auriculata is compared with the group of species close to D. graminoides, from which it can be distinguished by the lip with a long isthmus, provided with two rounded auricles at the base, instead of the sessile lip typical of the group. It is also compared with another Costa Rican endemic in the same complex, D. gracillima, from which it can be distinguished by the autogamous, mostly cleistogamous, flowers, the 3-lobed lip with rounded basal lobes, the high keel along the lip isthmus, and the bifid ligule of the column. Notes on the habitat and the ecology of the new species are provided.

    Hibiscus fabiana sp. nov. (Malvaceae) from the Guinea Highlands (West Africa) (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 69-74
    Details
    Publication Date: 2024-06-23
    Description: Hibiscus fabiana Cheek (sect. Furcaria, Malvaceae) is described from the Guinea Highlands of West Africa, and its taxonomic affinities and ecology are considered. Hibiscus fabiana has previously been confused with H. rostellatus but has red fleshy calyx ribs (vs not red and non-fleshy), the calyx surface is glabrous apart from 1-armed bristles (vs densely covered in minute white stellate hairs and bristles 2–5-armed), the leaves 3(–5)-lobed, bases truncate to rounded (vs 5-lobed, cordate). The conservation status of the new species is assessed using the IUCN 2012 standard as Vulnerable. In the context of the recently discovered extinction of the Guinean endemic Inversodicraea pygmaea G.Taylor (Podostemaceae), we discuss the 30 new species to science discovered in Guinea since 2005, all but one of which are also range-restricted and threatened, usually by development or habitat loss. We consider it urgent to avoid their extinction, ideally with in situ conservation using an Important PlantAreas approach.

    A new species of Eurystyles (Orchidaceae: Spiranthinae) from Costa Rica (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 65-68
    Details
    Publication Date: 2024-06-22
    Description: Eurystyles comprises about 23 species ranging from Mexico to northernArgentina. Six species are recognized in Mexico and Central America and three in Costa Rica. A new species, named E. uxoris, is here described and illustrated based on Costa Rican material. The species is similar to Eurystyles auriculata and E. standleyi, however, it differs by the smaller plants up to 3 cm tall, smaller leaves of less than 1.6 cm long, flowers with brown dorsal sepal and brown lip apex, petals callose or thickened at apex, and a pandurate lip. Information about distribution, habitat, ecology, etymology and phenology of the new species is provided. An updated key to the Costa Rican species of Eurystyles is presented.

    Senecio beltranii (Asteraceae, Senecioneae): a new caespitose species endemic to South Peru (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 2, pp. 162-166
    Details
    Publication Date: 2024-06-22
    Description: Senecio beltranii, a new species of Asteraceae (Senecioneae) belonging to S. ser. Suffruticosi subser. Caespitosi, is described from the highland mountains of southern Peru. Morphologically, S. beltranii is similar to S. algens, but can easily be distinguished by its subshrub matt-forming habit, the presence of scattered papillose trichomes on stems and leaves, its pinnatilobate leaf shape, larger involucre and pedicel length, calycular bracts nearly glabrous, larger phyllary length and by the larger number of phyllaries. The major differences between the species are outlined in a morphological comparison table and discussed. The IUCN status is defined as Vulnerable (VU).

    Three new combinations in Villaria (Octotropideae, Rubiaceae), an endemic genus from the Philippines (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 86-89
    Details
    Publication Date: 2024-06-22
    Description: Three new species combinations are made under Villaria for the Philippine endemics Hypobathrum coriaceum, H. multibracteatum and H. purpureum. Morphological features of these three Hypobathrum species revealed a closer resemblance with Villaria than with Hypobathrum, as the three Philippine endemics possess a unilocular ovary with parietal placentation; a character that is not found in any genera of Octotropideae except in Villaria. Lectotypes and a neotype are selected.
