The limestone regions of Yunnan-Guangxi-Guizhou in southern and southwestern China are regarded as some of biodiversity’s hotspots for China’s Gesneriaceae where numerous rare new species of Primulina have been, or are being, described over the past two decades. Primulina flexusa, a new lithophytic species of Gesneriaceae from a limestone hill in a Karst area, from Guizhou, China, is described here with color photographs. It is similar to P. curvituba, but can be easily distinguished by a combination of characteristics, especially in the shape and length of its capsule. We found only one population with approximately 100 mature individuals at the type locality. This new species is provisionally assessed as Critically Endangered [CR C1] by using IUCN criteria.

Primulina papillosa Z.B. Xin, W.C. Chou & F. Wen, a new species from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. linearifolia (W.T. Wang) Yin Z. Wang and P. pseudolinearifolia W.B. Xu & K.F. Chung, but can be easily distinguished by some combined characters, especially its leaf blades densely papillose-hispid. We found only one population at the type locality with no more than 200 individuals, so that this new species is provisionally assessed as Critically Endangered (CR) using IUCN Criteria.

Eight new fern species of Polystichum subg. Haplopolystichum sect. Haplopolystichum (Dryopteridaceae) are described and illustrated from Guizhou Province, southwestern China. These eight species include P. anshunense, P. asperrimum, P. confusum, P. kropfii, P. libingii, P. macrodon, P. perditum, and P. yifanii. Each of these eight species was discovered from only 1–2 limestone caves showing extremely narrow distributions. Therefore, all are classified as Critically Endangered (CR) following IUCN Red List criteria.

Pseudochthonius ramalhosp. nov. is described to Gruna do Vandercir cave, in the Serra do Ramalho karst area, southwestern Bahia, Brazil. This area has an extensive limestone outcrop, with several caves, and the occurrence of potential minerals that are financially attractive for mining projects. The new species shows troglomorphic characteristics such as the depigmentation of the carapace and absence or reduction of eyes. It is a rare troglobitic species, and following the criteria of IUCN, we categorized the species as Critically Endangered – CR, IUCN criteria B1ab(iii)+2ab(iii). According to Brazilian legislation, locations, where critically endangered species live, can be protected by law, and we consider this cave/region to be of maximal relevance for protection.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.
