A new species of Gesneriaceae, Primulina melanofilamenta Ying Liu & F. Wen from Guangxi, China, is illustrated and described. It is morphologically distinct from the most similar species P. eburnea and P. atroglandulosa by the color of the corolla, dark purplish black filaments, anthers backed with a beard of white hairs, the length of staminodes and the hairs of styles. The somatic chromosome number of P. melanofilamenta is also reported as 2n = 36.

“…Flower color in this genus shows a wide range of diversity and has even been used as the main diagnostic characteristics for new species, such as P. lutea (Yan Liu & Y.G. Wei) Mich. Möller & A. Weber, P. purpurea Fang Wen, Bo Zhao & Y.G Wei (Wen et al ) and P. heterochroa F. Wen & B. D. Lai (Wen et al ). However, the flower color is difficult to accurately describe, and its perception is easily affected by the condition of the material (such as fresh or dried), and can also vary between observers.…”

A new species of Primulina (Gesneriaceae) from a limestone area in southern China, P. rubella L.H. Yang & M. Kang, is described and illustrated. The new species has purple‐red flowers and is thus similar to P. lijiangensis, but differs by its petiole, leaf blade, cyme, filament, stigma and ovary. In adition, a molecular phylogenetic reconstruction indicated that P. rubella and P. lijiangensis belong to quite different clades. Instead, P. rubella appears to be closely related to the sympatric P. qingyuanensis, although these two species are obviously differentiated both in terms of flower color and other vegetative and floral characters. The conservation status of P. rubella is assessed as ‘Critically Endangered’ (CR) according to the IUCN red list categories and criteria.

“…Undoubtedly, the limestone areas of South-west and South China and North Vietnam are considered to be of the highest biodiversity and differentiation for Primulina (Gesneriaceae) (Wei et al, 2010;Wen et al, 2015). It is easily understood that very few species of Primulina in Fujian province have been recorded.…”

Primulina wenii (Gesneriaceae) is described and illustrated here as a new species. Morphologically, this new species resembles P. juliae (Hance) Mich. Möller & A. Weber, but it is distinct from the latter by some obvious features in leaf blade, bract, indumentum, corolla, filament, stigma and pistil. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid trnL-F intronspacer (trnL-F) DNA sequence data from the new species and its 22 relatives are used to determine the systematic position of the new species within Primulina. Molecular evidence suggests that P. wenii is strongly supported as a sister to a clade in which P. juliae is included. The conservation status of P. wenii is assessed as "Critically Endangered" (CR) according to IUCN Red List categories and criteria.
