Calanthe sieboldopsis, a new species, is here described and illustrated from Luoxiao Mountains, Jiangxi Province, eastern China. It is morphologically similar to C. sieboldii Decne. ex Regel, but differs from the latter in having smaller flowers, longer spurs, rectangular mid-lobes with emarginate apex (vs. elliptic mid-lobes with mucronate apex), disc with 3 ridges and the proximal ends of the lateral 2 ridges enlarged with light reddish spots and minute white hairs (vs. disc with 5 ridges and 2 rows of white short hairs at base) and pollinia equal in size (vs. unequal in size). A preliminary risk-of-extinction assessment, according to the IUCN Red List Categories and Criteria, is given for the new species.

Gastrochilus dulongjiangensis, a new species from Gaoligongshan National Natural Reserve, Yunnan, China, is described here. It is morphologically similar to G. pseudodistichus and G. fuscopunctatus, but can be distinguished from them by having the orbicular epichile, hypochile as wide as epichile and fusiform pollinia. A preliminary risk-of-extinction assessment shows that the new species should be regarded as Data Deficient (DD) according to the IUCN Red List Categories and Criteria.

Coelogynevictoria-reginae, a new species of sectionProliferae, from Natma Taung (Mt.Victoria) National Park, Chin State, Myanmar, is described and illustrated. It is morphologically similar to C.prolifera, but the clustered pseudobulbs, pure brownish- red flowers and column wing with irregular notches at the apex of the new species differ from the other species. A preliminary risk-of-extinction assessment shows that the new species is regarded as EN C2a[i] according to the IUCN Red List Categories and Criteria.

Abstract—A new species with verrucose fruits and relatively large leaves, Eugenia antilahimenae, is described from the northeast of Madagascar. It is known from the protected areas of Makira and Masoala in lowland rainforests west and north of the Baie d'Antongil. We provide a detailed description of the species, illustration, a table comparing morphologically similar taxa, and preliminary assessment of the risk of extinction following the IUCN Red List Categories and Criteria, which indicates a status of “Least Concern.”

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].

Odontochilusputaoensis, a new species of Orchidaceae, is described and illustrated from Putao Township, Kachin State, Myanmar.Odontochilusputaoensisis close toO.duplex, but can be easily distinguished from the latter by having a light yellow lip, a bisaccate hypochile with a small, erect, blade-like and emarginate callus within each sac, a mesochile with a pair of dentate-pectinate flanges and a bilobed epichile with a pair of widely diverging lobes that are erect and concave. An identification key to the Southeast Asian species ofOdontochilusand colour photographs ofO.putaoensisare provided. A preliminary conservation assessment according to the IUCN Red List Categories and Criteria is given for the new species.

Liparis popaensis, a new species of Orchidaceae, is described from Popa Mountain National Park, central Myanmar. Liparis popaensis is morphologically similar to L. odorata but it differs from the latter by having oblong-lanceolate dorsal sepal, column with two triangular wings and lip with a pair of subconical and basally adjoining calli at its base. Identification key and colour photographs are provided. A preliminary conservation assessment according to the IUCN Red List Categories and Criteria is given for the new species.

Ocimum sebrabergensis, here described as new species, has a restricted range and is only known from the Zebra Mountains within the Kaokoveld Centre of Endemism, northwestern Namibia. These shrubs grow on clayey soil among greyish black rocks of anorthosite. Diagnostic characters for O. sebrabergensis include the mauve-coloured corolla with four orbicular lobes on the posterior lip and the calyx which has the lateral lobes of the anterior lip asymmetric lanceolate. Ocimum sebrabergensis is placed in Ocimum subg. Ocimum sect. Hiantia subsect. Hiantia ser. Serpyllifolium. A comparison of some of the more prominent morphological features to differentiate between O. sebrabergensis and its possible nearest relatives, O. burchellianum and O. fimbriatum, are provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.

Eremitis limae, a new species of Parianinae (Poaceae, Bambusoideae, Olyreae) endemic to the coastal forests of Bahia, Brazil, is described and illustrated. It is morphologically similar to species of Eremitis with characteristically narrow leaves: E. linearifolia, E. parviflora, and E. riodocensis. We discuss the morphological characters distinguishing the new species from its close relatives, and we also present illustrations, photos, and a distribution map. Eremitis limae is classified as Endangered (EN) according to the IUCN Red List categories and criteria.

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.

Spiradicliskarstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S.jingxiensis, but differs from the latter mainly by its inflorescences with 5–9 flowers, its 1.5–2.4 mm long peduncles, its stipules shorter than 1 mm and the 5–12 pairs of secondary veins. The conservation status is assessed as “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.
