Dryopteriswulingshanensis (Dryopteridaceae), a new species from Hunan, China.

ABSTRACT: Dryopteriswulingshanensis, a new species growing on limestone in the Wulingshan Mountains, Hunan, China, is described and illustrated. This species is most similar to D.jishouensis and D.gymnophylla on general morphological traits, such as the form of scales, rhizome and sori, but differs by the number of vascular bundles at the base of the petiole, length to width ratio of lamina, stalk length of basal pinnae, division of the lamina, apex form of the pinnule and habitat. Moreover, molecular phylogenetic analysis using the chloroplast rbcL gene suggested that D.wulingshanensis, as the sister group of D.jishouensis, is a monophyletic clade. According to its restricted geographic range, small populations and few individuals, D.wulingshanensis should be considered endangered, according to the IUCN Red List criteria.

Cyrtomiumadenotrichum (Dryopteridaceae), a new species from Guangxi, China.

Project description:Cyrtomiumadenotrichum Y. Nong & R.H. Jiang (Dryopteridaceae), a new species from Guangxi, China, is described and illustrated. This new species is similar to C.nephrolepioides (Christ) Copel., C.obliquum Ching & K. H. Shing ex K. H. Shing, C.sinningense Ching & K. H. Shing ex K. H. Shing and C.calcis Liang Zhang, N.T.Lu & Li Bing Zhang in having erect rhizomes, dense, leathery lamina and rounded sori, but it can be easily distinguishable by its stipe sparsely glandular, base obvious oblique, basiscopic base truncate, acroscopic base auriculate or ovate.

Lysimachia huangsangensis (Primulaceae), a New Species from Hunan, China.

Project description:A new species, Lysimachia huangsangensis (Primulaceae), from Hunan, China is described and illustrated. The new species is closely related to L. carinata because of the crested calyx, but differs in the leaf blades that are ovate to elliptic and (3-)4.5-9 × 2-3.4 cm, 2-5-flowered racemes, and the calyx lobes that are ovate-lanceolate and 5-6 × 3-4 mm. The systematic placement and conservation status are also discussed.

Chrysosplenium sangzhiense (Saxifragaceae), a new species from Hunan, China.

Project description:Chrysosplenium sangzhiense Hong Liu, a new species from Hunan, China, is described and illustrated. The phylogenetic analysis revealed that the new species belongs to subgen. Chrysosplenium and is closely related to C. grayanum, C. nepalense and C. sinicum. The chromosome number of the new species is 2n = 46, indicating a novel basic number x = 23 in Chrysosplenium that is different from other species. This also suggests that C. sangzhiense is probably an allopolyploid derivative of a species with x = 11 and one with x = 12. Morphologically, C. sangzhiense can be easily distinguished from C. grayanum, C. nepalense, C. sinicum and C. cavaleriei, a species not included in our phylogenetic analysis by a suite of characters relating to the sterile shoots, basal leaves, cauline leaves, flowering stem, sepals, disc, capsule and seed. A global conservation assessment is performed, and classifies C. sangzhiense as Least Concern (LC).

Lysimachiafenghwaiana (Primulaceae), a new species from Hunan Province, China.

Project description:A new species, Lysimachiafenghwaiana G.Hao & H.F.Yan (Primulaceae), from Hunan Province, China, is described and illustrated. This new species belongs to Lysimachiasubgen.Lysimachiasect.Nummularia and is morphologically similar to L.crista-galli and L.carinata, but is distinctive in its leaf shape and arrangement of flowers. It can be further distinguished from L.crista-galli by the absence of calyx lobule spur, and from L.carinata by the black glandular striates in the corolla lobes, rather than punctate.

Primulina jiuyishanica (Gesneriaceae), a new species from Hunan, China.

Project description:Primulina jiuyishanica K. Liu, D.C. Meng & Z.B. Xin, a new species of Gesneriaceae from Hunan, China, is described and illustrated. The new species is morphologically similar to Primulina fimbrisepala (Hand.-Mazz.) Yin Z. Wang, but differs in its elliptic to broadly elliptic leaf blade with broadly cuneate base, peduncle densely pubescent with sparse glandular hairs, corolla throat with no purple spots inside, the yellow patch in the throat densely glandular-pubescent and pistil densely glandular-pubescent. Photographs and descriptions of the new species are provided below.

Primulaxinningensis (Primulaceae), a new species from karst caves in Hunan, China.

Project description:Primulaxinningensis Wei Zhang bis & J.W.Shao, a new species from Hunan Province, China, is described. Its leaf morphology is similar to the P.merrilliana complex and flower morphology similar to P.cicutariifolia, but it can be distinguished from the former by the black pollen sac, corolla lobes apex obviously emarginate and can be differed from the latter by cotyledon triangular obovate, plants densely covered with glandular hairs and special habitat (karst caves). The whole plastid genome of this new species is 151, 601-151, 630 bp in length. Based on the whole plastid genome sequences, phylogenetic trees revealed that the new species did not genetically relate to the above two mentioned morphologically similar species, but it was closely related to P.hubeiensis. Currently, only three populations were discovered within a small distribution area, thus, it is preliminarily considered as Vulnerable (VU) according to criteria of the IUCN Red List.

Lycoris wulingensis, a dwarf new species of Amaryllidaceae from Hunan, China.

Project description:Lycoris wulingensis S.Y. Zhang, a new species from Hunan Province (central South China), is described and illustrated. This new species is a fertile diploid plant and its karyotype is 2n = 22. It is most similar to L. × haywardii in morphology, but the latter is a hybrid species and distributed in East China and the plant is much larger. Amongst the original species, L. wulingensis is similar to L. radiata, but differs from it in its flowers being rose-red (vs. red) and stamens and tepals are nearly the same length (vs. stamens significantly longer than tepals).

A new species of Odorrana (Anura, Ranidae) from Hunan Province, China.

Project description:A new species, Odorrana sangzhiensis sp. nov., is described, based on five specimens from Sangzhi County, Zhangjiajie City, Hunan Province, China. Molecular phylogenetic analyses, based on mitochondrial 12S rRNA and 16S rRNA gene sequences, strongly support the new species as a monophyletic group nested into the O. schmackeri species complex. The new species can be distinguished from its congeners by a combination of the following characters: (1) body size medium (SVL: 42.1-45.1 mm in males, 83.3-92.7 mm in females); (2) dorsolateral folds absent; (3) tympanum diameter 1.53 times as long as the width of the disc of finger III in females; 2.3 times in males; (4) dorsal skin green with dense granules and sparse irregular brown spots; males with several large warts on dorsum; (5) two metacarpal tubercles; (6) relative finger lengths: I ≤ II < IV < III; (7) tibiotarsal articulation beyond the tip of the snout; (8) ventral surface smooth in females; throat and chest having pale spinules in adult males; (9) dorsal limbs green or yellow green with brown transverse bands; and (10) paired external vocal sacs located at corners of the throat, finger I with light yellow nuptial pad in males. This discovery increases the number of Odorrana species to 59 and those known from China to 37.

A new freshwater species of Pinnularia (Bacillariophyta) from Hunan Province, China.

Project description:This study describes a new species of Pinnularia, P.hupingensissp. nov., on the basis of light and scanning electron microscope images. Pinnulariahupingensissp. nov. is characterised by its linear valve outline, extremely divergent striae, and very large hexagonal central area occupying ca. 1/5-1/8 of the valve length. The primary and secondary sides of the valve and the internal proximal raphe fissures are discussed. The new species is compared to similar taxa of the genus Pinnularia.
