Abstract—Siphocampylus nebularis is a new species endemic from the Serra do Mar mountain range in the Paraná state, Brazil. It is morphologically close to S. fulgens due its alternate phyllotaxis, sparsely denticulate leaves, and flowers with reddish corolla tube, differing mainly by the shorter corolla tube, longer calyx lobes, and coriaceous leaves observed in the new species. The new taxon is here described and illustrated. We also propose the inclusion of S. nebularis in the IUCN Red List as an endangered (EN) species due its narrow distribution and the decline of the quality of its habitat.

A New Species

Valeriana sobraliana, a new species from the highland grasslands of the Atlantic Rainforest Domain, Southern Brazil, is described and illustrated. The new species shares morphological affinities with V. catharinensis, V. organensis and V. ulei, but differs mainly by the leaves strongly discolorous and long-petiolate, as well as by the lanceolate and larger bracteoles, by the larger staminate flowers and by the elliptic achenes. It also differs by the distribution restricted to the High Altitude Tropical Grasslands of the Serra do Mar mountain range, Paraná state and border with the Santa Catarina state, in a remarkable disjunction with the other related species. Additionally, we provide the preliminary conservation status assessments using IUCN Red List categories and criteria, as well as a checklist and a key to the species of Valeriana in the Paraná state.

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 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.

Abstract—Valeriana caparaoensis, a new species from the High Altitude Tropical Grasslands of Southeastern Brazil, is described and illustrated. The new species is known only from the Serra do Caparaó massif, between the states of Minas Gerais and Espírito Santo, Southeastern Brazil. It shares morphological affinities with V. catharinensis and V. polystachya, the first restricted to Brazilian Subtropical Highland Grasslands, and the last restricted to Lowland Grasslands of Southern Brazil, Uruguay and Argentina. Besides the great geographical disjunction, the new species differs from the other two species by the pinnately lobed proximal leaves, by the lanceolate distal lobes and longer pseudopetioles in distal leaves, by differences in the size of the flowers, and by the rounded to ovate and broader achenes. Additionally, we provide the preliminary conservation status assessments using IUCN Red List categories and criteria, as well as an updated checklist and a key for Valeriana species from Southeastern Brazil.

Mitreola crystallina was proposed in 2006, but not valid. Here, we validate the name by giving a complete description, diagnosis, and illustration as a new species of Loganiaceae. Morphologically, it is most similar to M. pedicellata, but can be distinguished by its stems erect (vs. creeping), corolla lobes blue (vs. white), and stamens inserted at or near base of the corolla tube (vs. middle to nearly mouth of corolla tube). It is endemic to the shady cliffs of limestone forests of Malipo County, southwest China. The conservation status was assessed as data deficient (DD) according to the IUCN Red List categories and criteria. And a key to species of Mitreola in China is provided.

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.
