Petrocosmeaduyunensis (Gesneriaceae), a new species from Guizhou, China.

ABSTRACT: Plants belonging to the genus Petrocosmea are rare and small herbs difficult to find in the wild. In the present study, a new species, Petrocosmeaduyunensis, from Guizhou, China, is described. The species is most similar to P.leiandra and differs from it by a distinctly recurved abaxial corolla lip, free anthers and included pistil. Detailed morphological comparisons are given. One population with about 100 mature individuals was found at the type locality. This new taxon was assessed as "Data Deficient" (DD) according to the IUCN standards.

Hemiboea suiyangensis (Gesneriaceae): a new species from Guizhou, China.

Project description:The limestone areas in south China are a major biodiversity hotspot for terrestrial biomes. Hemiboea, with 34 species and 5 varieties, mainly distributed in south China, is one of the characteristic plant groups in limestone areas. Hemiboea suiyangensis, a new species of Gesneriaceae from limestone areas in Guizhou, China, is described and illustrated. The new species is easily distinguished from other Hemiboea species by having an oblique-infundibular corolla with an abaxially gibbous swelling on the upper half of the tube and with a densely villose throat and lower lobes. Hemiboea suiyangensis is similar to H. omeiensis W. T. Wang in the shape of the leaf blade, but differs from the latter by the shape of the petiole, involucre, calyx and corolla and the colour of the corolla. The conservation status of this species is considered to be "Critically Endangered" (CR) according to IUCN Red List Criteria.

Hemiboeaalbiflora, a new species of Gesneriaceae from Guizhou, China.

Project description:Hemiboeaalbiflora X.G.Xiang, Z.Y.Guo & Z.W.Wu, sp. nov., a new species of Gesneriaceae from Guizhou, China, is described and illustrated. This species was previously listed informally as a variety of H.gamosepala, but it differs significantly from H.gamosepala by its 5-parted calyx from the base, longer peduncle, white corolla and longer pistil. Based on recent extensive observations, this new species is similar to H.cavalerieivar.paucinervis and H.subcapitata but differs from them by its longer petiole, larger involucre, white corolla and longer staminal filaments. The conservation status of this species is considered to be "Vulnerable" (VU) according to the IUCN Red List Categories and Criteria.

Oreocharisodontopetala, a new species of Gesneriaceae from Guizhou, China.

Project description:A new species, Oreocharisodontopetala Q.Fu & Y.Q.Wang from Guizhou Province in southwest China, is described and illustrated, based on morphological comparison with existing species. It is morphologically most similar to O.elegantissima, but can be easily distinguished by its adaxially bullate leaf blade, abaxially conspicuous reticulate veinlets, brown-purple peduncles, triangular adaxial corolla lobes and abaxial corolla lobe margins bearing 4-10 long teeth, glabrous style and shorter stamens with confluent thecae at the apex, as well as leaf epidermal characters.

Petrocodon luteoflorus (Gesneriaceae), a new species from karst region in Guizhou, China.

Project description:A new species of Gesneriaceae, Petrocodon luteoflorus Lei Cai & F.Wen was first described and illustrated from Maolan National Nature Reserve, Libo County, Guizhou Province, China. The diagnostic characters and notes of this species between its most morphologically similar species, P. dealbatus Hance, a detailed description, colour photographs, etymology, as well as distribution and habitat, are also provided in this paper.

Oreocharis tetrapterus (Gesneriaceae), a new species from East Guangxi, China.

Project description:A new species, Oreocharis tetrapterus F.Wen, B.Pan & T.V.Do (Gesneriaceae) from Gupo Mountain area, Hezhou city, Guangxi Zhuangzu Autonomous Region, China, is described and illustrated. The new species has a zygomorphic tetramerous corolla with two adaxial and two abaxial lobes and two fertile stamens in the posterior position, making this a unique combination of floral characteristics in the expanded Oreocharis.

Ophiorrhizashiqianensis (Rubiaceae), a new species from Guizhou, China.

Project description:A new species of the genus Ophiorrhiza L. (Rubiaceae), Ophiorrhizashiqianensis L.D.Duan & Yun Lin, is described, illustrated and photographed from Shiqian County, Guizhou Province, South-western China. This species was found growing at the side of streams in evergreen broad-leaved forests in mountains at elevations of 960-1100 m. The new species is morphologically similar to Ophiorrhizahunanica H.S.Lo, but differs from the latter by the glabrous, glabrescent or pilose stems, the 5-10 cm long subterranean stem internodes, the glabrous or pilose petioles, the 3-5 mm long stipules, the purple corolla lobes, the ca. 12 mm long style and included stigmas in long-styled flowers and the 3-4 × 8-10 mm, glabrous or glabrescent capsules.

Primulina flexusa sp. nov. (Gesneriaceae) from Guizhou Province, China.

Project description: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.

Dysosmavillosa (Berberidaceae), a new species from Guizhou, Southwestern China.

Project description:A new species, Dysosmavillosa Z.W.Wang & H.C.Xi, is described and illustrated based on collections from the Yueliang Mountains in Congjiang County of Guizhou, Southwestern China. It is morphologically similar to D.difformis (Hemsl. & E.H.Wilson) T.H.Wang ex T.S.Ying, but can be easily distinguished from D.difformis by its inflorescences bearing a greater number of flowers (5-13 vs. 2-5), white-villous stems, petioles, and abaxial leaf blade, and stigma dark purple-red. In addition, we also compare this new species to the three species of Podophyllum (i.e., P.glaucescens J.M.H.Shaw, P.hemsleyi J.M.H.Shaw & Stearn, and P.trilobulum J.M.H.Shaw) which are insufficiently known and listed as putative members of Dysosma in Flora of China. Dysosmavillosa can also be easily distinguished from P.glaucescens (7-flowered; to 40 cm tall) and P.hemsleyi (4-flowered; to 40 cm tall) by its inflorescences bearing a greater number of flowers, relatively smaller stature (9-23 cm tall), stems, petioles and abaxial leaf blade densely white-villose. Although the stems and petioles of P.trilobulum also possess fine short hairs, it can be easily distinguished from D.villosa by its trilobulate leaves, inflorescence with fewer flowers (2-5), and the position of inflorescence (inserted at or above midpoint on petiole of upper leaf).
