Gyrocheilos taishanense G.T. Wang, Yu Q. Chen & R.J. Wang (Gesneriaceae) from south China is described and illustrated with photographs. It is morphologically similar to G. microtrichum W.T.Wang, but it is distinguished by its glabrous or sparsely hairy pedicels, zygomorphic calyx with hairs in unequal length, and slightly bilobed adaxial corolla lips. Molecular phylogenetic analysis based on nuclear ITS and plastid trnL-F sequences strongly supported this new species as sister to a clade comprising the previously described Gyrocheilos species (100% posterior probability and bootstrap support). The new species is evaluated here as Least Concern (LC) according to the IUCN Red List Categories and Criteria.

A New Species

Begonia leipingensis D. K. Tian, L. H. Yang & C. Li (2n = 30), a new species in Begonia sect. Coelocentrum from the limestone area of Guangxi, China. B. leipingensisis is easily distinguished from any other compound-leaved species in Begonia by its large variation in petiolule number and its unique spirally-arranged petiolule pattern, which has never been seen in Begoniaceae before and rarely seen even in other angiosperm taxa. Besides having non-overlapping flowering periods, it is clearly different from B. fangii, the most morphologically similar species in the same section and with the same chromosome number. In addition to its unique petiolule pattern, B. leipingensis has longer abaxial wings, shorter internodes, and usually larger leaves, leaflets and habit. Molecular phylogenetic analysis showed that B. leipingensis formed an independent lineage belonging to Sect. Coelocentrum. Morphological and phylogenetic evidence strongly supports this species as a new taxon in Sect. Coelocentrum of Begonia. B. leipingensis was assessed to be critically endangered based on criterion outlined by IUCN Red List Categories and Criteria.

Begonia fenshuilingensis X.X.Feng, R.K.Li & Z.X.Liu, a new species in Begonia sect. Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southeastern Yunnan, China, is here described and illustrated. It morphologically resembles B. dryadis and B. daweishanensis, but differs by its fleshy trigonous-ellipsoid capsules without wings. Molecular phylogenetic analysis of ITS sequence data supports the new species as monophyletic, and distinct from the two similar species. Due to its limited distribution, we consider the new taxon as “Vulnerable D2” (VU D2) according to the IUCN Red List Categories and Criteria.

A new species, Dimetia brevipetiolata R. J. Wang, from Guangxi Zhuang Autonomous Region, China, is described and photographed. Morphologically, it is similar to D. scandens and D. ampliflora with respect to their terete stem, lanceolate and thick papery leaves and compound-cymose inflorescences, but differs in prostrate habit, subsessile leaves, rounded leaf base, nearly glabrous corolla, and indehiscent capsules. The molecular phylogenetic analysis revealed that D. brevipetiolata was embedded in the Dimetia clade and closely related to D. auricularia. It is evaluated as Least Concern according to IUCN Red List Categories and Criteria.

Involucrella lithophila from the limestone area of Guangxi, China, is described and illustrated here. It is most similar to Hedyotis kurzii and Involucrella chereevensis in having tetragonal stems, slender pedicels and loculicidally dehiscent capsules, but it differs from the former by its 3–5 (–7)-lobed stipules, heterostylous and white flowers and depressed seeds, and from the latter by its 2–4 secondary leaf veins and heterostylous flowers. The molecular phylogenetic analysis revealed that this new species was embedded in the Involucrella clade and closely related to I. chereevensis. It is evaluated as Least Concern according to IUCN Red List Categories and Criteria.

Begonia pseudoedulis, a new species in Begonia sect. Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southern Guangxi of China, is here described and illustrated. It morphologically resembles B. edulis H.Lév. and B. dielsiana E.Pritz. ex Diels but differs easily by its hairy petioles and inflorescences, and red hispidulous flower tepals, ovary and capsules. The molecular phylogenetic analysis based on ITS supported that the new species was a monophyletic lineage, separating from both B. dielsiana and B. edulis. Due to its isolated distribution with several small populations, which are possibly disturbed by human activities, the species is considered as “Near Threatened” (NT) according to the IUCN Red List Categories and Criteria.

Hedyotis taishanensis is described as a new species from China. It is similar to H. acutangula, but obviously differs in unbranched herbal stems with slightly winged ridges, petiolated leaves, abaxially pubescent stipules, terminal pleiochasium inflorescence. The phylogenetic analysis from nuclear ITS and plastid petD sequences of 27 taxa revealed that H. taishanensis was an independent lineage but closely related to the clade including the sympatric species endemic to the Pearl River Delta, Guangdong, China. It was evaluated as Least Concern according to the IUCN Red List Categories and Criteria.

A New Species

Ischaemum mistryi, a new species from the Sub-Tropical evergreen forest of Tilari Ghat, Maharashtra, India, is described and illustrated. This grass is unique with its leaves drooping, mostly congregated near the base, basal sheath villous, culms compressed at the base, lower glume of the sessile spikelet linear-lanceolate to oblongish tapering and slightly curled upwards, without a sub-apical ridge, nodules absent (if present 2–4 obscure) on its keels, and upper lemma of sessile spikelet bi-partite. Morphologically it is somewhat similar to I. mangaluricum, I. travancorense and I. barbatum. We provided a table of its detailed comparison with close species as mentioned above. According to IUCN Red List Categories and Criteria, we have assessed this new species as Critically Endangered (CR). The photo plates and illustration of the grass are given to facilitate its proper identification. A short discussion is also provided at the end.

Primulina silaniae X.X.Bai & F.Wen, a new species of Primulina Hance (Gesneriaceae) from the limestone area of Wangmo County, Guizhou Province, is described and illustrated. The new species is similar to P. spiradiclioides Z.B.Xin & F.Wen, but can be easily distinguished from the latter by a combination of characteristics, especially in the lateral veins of its leaf and floral shape and tube. At present, three populations in one locality of this new taxon were found, totaling about 600 mature individuals. According to the IUCN Red List Categories and Criteria (Version 3.1), the species is provisionally assessed as Vulnerable [VU D1].

A New Species

Begonia giganticaulis, a huge new species in Begonia sect. Platycentrum of Begoniaceae from southern Xizang (Tibet) of China, is described. Morphologically, it is mostly similar to B. longifolia and B. acetosella, but clearly differs from the former mainly by its dioecious and taller plants, sparse hairs on abaxial veins, longer inflorescence, unique shape of fruits, and differs from the latter mainly by its late and longer flowering time, 6-tepals of female flower and 3-loculed ovary. The phylogenetic analyses also support the separation of the new species from other taxa. Based on the current data, its conservation status is assigned to Endangered (B2a) according to the IUCN Red List Categories and Criteria.
