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

ABSTRACT: 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.

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).

Hedyotislongiramulis (Rubiaceae), a new species from south China.

Project description:Hedyotislongiramulissp. nov. (Rubiaceae) is described from Guangdong Province, China. It is similar to H.caudatifolia but differs in having puberulent, more or less tetragonal and decussately sulcate juvenile stems, waxy leaf surface, short inflorescence peduncles, high length ratio of corolla lobe to tube, and subglobose capsules. The phylogenetic analysis reveals that H.longiramulis is sister to H.pubirachis. Dimorphism concerning pollen size was observed in the heterostylous flowers. The complete chloroplast genome of the new species comprises a typical quadripartite structure of 153,616 bp in length, with two inverted repeats of 25,457 bp, a large single-copy of 85,050 bp and a small single-copy of 17,652 bp. It contains 112 unique genes, including 79 protein-coding genes, 29 tRNA genes, and four rRNA genes, the GC content of the chloroplast genome is 32.4%. The new species is provisionally evaluated as "Least Concern" because it is common and well-protected in two Provincial Nature Reserves.

Spiradicliskarstana (Rubiaceae), a new species from Yunnan, China.

Project description: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.

Hypericumliboense (Hypericaceae), a new species from Guizhou, China.

Project description:Hypericumliboense M.T.An & T.R.Wu, sp. nov. (Hypericaceae) is a newly described species found in the Maolan National Nature Reserve of Guizhou Province, where it grows in rocky habitats without soil on karst mountain tops. In this study, key morphological characters were compared between the new species and the other known Hypericum species of Hypericaceae. DNA sequences were extracted from the leaves of the new species, with nuclear gene sequences (ITS) generated to reconstruct phylogenetic trees and describe its phylogenetic position in relation to other species of Hypericum. Our results show that the proposed new species has the typical characteristics of the genus Hypericum in morphology being similar to Hypericummonogynum, but differing in its sessile and semi-clasped leaves, long elliptical to long circular leaf blades, thickly papery to thinly leathery, with entire and wavy leaf margins. The abaxial side of the leaves is covered with white powder, giving them a grey-white appearance. The main lateral veins of the leaves are 8-15-paired, and the midvein on both sides is convex. The main lateral veins and midvein branch are conspicuous, with tertiary venation forming a network on the leaf surface and appearing prominently sunken. The inflorescences are 1-3-flowered, with a large calyx and conspicuous veins. The molecular phylogenetic analysis (PP = 1.00) provided substantial evidence for the proposition of H.liboense as a new species within Hypericum. Morphological and molecular evidence is presented, corroborating the proposition of the new species, including a comprehensive account of the distinctive morphological attributes of H.liboense, along with its key distinguishing features from similar species.

Primulapingbaensis (Primulaceae), a new species from Guizhou, China.

Project description:Primulapingbaensis Na Zhang, X.Q.Jiang & Z.K.Wu, a new species of Primulaceae from Gaofeng Mountain of Pingba county, Guizhou, China, is described and illustrated. Morphological evidence supports P.pingbaensis as a member of P.sect.Petiolares on account of scape elongating, pedicels conspicuously thickening in fruit, and its capsule cracking irregularly round the top and crumbling away. Amongst the members of subsect. Davidii, the new species is characterized by having a uniquely smooth leaf blade due to inconspicuously raised veinlets and homostylous flowers with the style usually extending beyond the anthers. The distribution, phenology and conservation status of the new species are also provided.

Sinosenecioyangii (Asteraceae), a new species from Guizhou, China.

Project description:A new species Sinosenecioyangii D.G. Zhang & Q. Zhou (Asteraceae, Senecioneae) from Guizhou Province, China, is described and illustrated based on its morphological characteristics and molecular evidence. It closely resembles S.confervifer and S.guangxiensis, the former in the scapigerous habit and smooth and glabrous achene surface, the latter in the calyculate involucre and purple abaxial leaf surface, and both in the shape and indumentum of leaf lamina, but differs markedly from the latter two in having fewer capitula and epappose achenes. Phylogenetic analysis based on nrITS and ndhC-trnV sequences shows that this new species belongs to the S.latouchei clade and is sister to S.guangxiensis with moderate support.
