A New Species

Frithia N.E.Br (Mesembryanthemaceae), formerly thought to be a monotypic genus, has been found to comprise two species. Populations from the eastern parts of the distribution range of Frithia pulchra N.E.Br. are recognised as a distinct species,  Frithia humilis PM Burgoyne The genus has a limited distribution, although present in three provinces of South Africa, namely Gauteng, North-West and Mpumalanga. The two window-leaved species are allopatnc and morphological differences between the roots, leaves, flowers, pollen, capsules and seeds are discussed. A formal description of the new species, an identification key and a distribution map of the two species are provided.

Tigridiopalma longmenensis, a new species from Guangdong, China, is described. This species differs from its ally, T. magnifica, by the polychasium consisting of scorpioid cymes, hypanthium with carinas on angles, and longer stamens with a conspicuously white or pink spur at the connective base of anther. A diagnosis and a distribution map of the two species are also provided. The complete chloroplast genome of T. longmenensis was reported here. Phylogenetic analyses based on complete chloroplast genomes from T. longmenensis and other 15 Melastomataceae species indicated that T. longmenensis is sister to T. magnifica. The discovery of T. longmenensis terminates Tigridiopalma as a monotypic genus.

A New Species

In this study, we describe a new orchid species, Goodyera malipoensis, from Yunnan, China. We have performed morphological and molecular analyses on this new species. A detailed comparison between the newly discovered orchid and other members of Goodyera was conducted. The new plant is characterized by having a dense brownish green pubescence on the peduncle. Its ovate-lanceolate petal is unique in Goodyera genus. The hypochile is deeply concave-saccate, and inside there are two papillose rows on each side. These features distinguish the new orchid from all other known species of Goodyera. The molecular study based on nuclear ribosomal ITS sequence data and morphological differences support G. malipoensis as a distinct species.

A New Species

A re-examination of the herbarium material has allowed to describe a new species, Corbichonia exellii, occurring in Southern Africa (Angola, Namibia and South Africa). C. exellii represents the third species in the genus. Morphological differences between all three Corbichonia species (C. decumbens, C. rubriviolacea, and C. exellii) are provided. The description of the genus is defined using the newly discovered characters (reproductive features). The taxonomy of all Corbichonia species (synonyms included) is provided, as well as maps for all species. The lectotypes of Orygia decumbens (basionym of Corbichonia decumbens) and O. mucronata (synonym of C. decumbens) are designated on specimens preserved, respectively, at BM and K. The genus Corbichonia, recently placed in Lophiocarpaceae, is markedly different from the core genus Lophiocarpus on the basis of embryological, morphological and carpological characters, and deserves further investigation concerning its taxonomic status.

A New Species

Recent botanical explorations in Sierra Madre Occidental in Durango, Mexico, led to the discovery of a new species which according to its morphology belongs to Salvia sect. Brandegeia. The new taxon is morphologically most similar to S. oresbia from central Mexico, against which it is thoroughly compared. Additionally, it is presented a synopsis of the section in order to provide updated and standardized descriptions for those species known only in base to their protologues, which allows a more detailed and precise comparison in respect to the new species. The morphological examination of the species in the section also revealed that the recognition of S. sharpii as a distinct species from S. blepharophylla is not justified; consequently, it is reduced to synonymy. An identification key, a distribution map, photographs, and a drawing of the new species are also presented.

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.

A New Species

A phylogeny of all nine subgenera of Drosanthemum, based on chloroplast sequence-data, is presented. The results confirm some previously published facts, e.g. that D. zygophylloides is sister to Drosanthemum. We propose to treat this species as a new monotypic genus, Lemonanthemum, which differs from Drosanthemum in features of the leaves and fruit-stalks. In Drosanthemum s.s., the small subg. Quadrata, characterized by 4-locular fruits, is highly supported as sister to the remainder of Drosanthemum (where fruits are 5-locular). Further, our data support the transfer of Delosperma pubipetalum to Drosanthemum (where a nomenclatural change is also made). The pubescent petals, 5-locular fruits with narrow covering membranes and downward-pointing hair-like papillae on the branches suggest that D. pubipetalum is close to D. papillatum and belongs to subg. Quastea. Another species, D. badspoortense, which had been placed in D. subg. Quastea on account of its narrow covering membranes, is shown to belong to Delosperma and also lacks the unique structure of the fruit-stalk of Drosanthemum. In addition, a new species, D. overbergense, is described from disjunct patches of remnant renosterveld within the Overberg and near Albertinia, in the Western Cape of South Africa. Morphological characteristics suggest that this species belongs to subg. Xamera, but this was not corroborated by our molecular data. Finally, a new name—Drosanthemum calcareum—is proposed for the illegitimate D. intermedium and a lectotype (at BOL) is designated for D. pubipetalum. The lectotypification of D. badspoortense is also proposed.

Allium undulatitepalum (Amaryllidaceae) is described as a new species from the Antalya Province of Turkey. It belongs to the section Melanocrommyum and is endemic to the south-western region of Turkey. The new species is a close relative of A. orientale, but according to results of the ITS sequences, and based on the morphological differences presented in the description, it is clearly different from its relative. A phylogenetic tree, distribution map, illustrations, pollen and seed microphotographs, karyo-morphology, as well as notes on the biogeography and ecology of the new species are provided.

A New Species

During the examination of the rich collections of the genus, Rhynchosia housed in some South African herbaria (BNRH, NH, PRE), a new and yet to be described species was discovered. The species is similar to R. pauciflora in its erect habit, linear or oblong leaflets, and solitary flowers. The study is based on the examination of herbarium specimens. Measurements were taken from vegetative and reproductive parts. We describe here R. ngwenyii. The new species differs from R. pauciflora by its broader (24–38 mm), linear-lanceolate to oblong-lanceolate terminal leaflets that are without conspicuous revolute margins, wing petals that lack sculpturing and shorter peduncles, (25)30–42 mm. It is distributed in KwaZulu-Natal and Mpumalanga Provinces in South Africa. The preliminary conservation status is evaluated as Endangered. A detailed description, illustration, distribution map, and the information on ecology, as well as phenology are also presented.
