A New Species

A distinctive, previously undescribed species of Epimedium (Berberidaceae), which we propose naming E. tianmenshanensis, was found during a floristic survey in Hunan, China. It is similar to E. baojingense and E. franchetii, but has smaller flowers and petals with a short, blunt spur. We determined the phylogenetic position of the new species using DNA sequences of nuclear ITS and two chloroplast regions (atpB-rbcL intergenic spacer and matK). Molecular evidence indicates that E. tianmenshanensis occupies a distinct group related to E. baojingense.

Impatiens bullatisepala (Balsaminaceae), a new species supported by morphological and phylogenetic evidence from Fanjing Mountain, Guizhou province in China, is described here. It is morphologically similar to I. davidii but can be distinguished by its dorsally ridged lateral sepals with sunk reticulate veins and bullate projections on abaxial surface, 2–2.5 cm deep saccate lower sepal with ca. 0.8 cm long narrowly triangular tip at the mouth, and broadly ovate dorsal petal. Phylogenetic analyses of a combined dataset of nuclear ITS and plastid atpB-rbcL intergenic spacer DNA sequences furtherly confirmed its novelty.

A New Species

A new species of Cymbidium (Orchidaceae), Cymbidium biflorens, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. biflorens is similar to C. rhizomatosum, but differs by its leafless, coralline rhizome, normally two flowering periods, a shorter scape, inflorescence with 1–2 flowers, greenish flowers with longer pedicel and ovary, subelliptic petal, petals and lip not fully opened. Molecular analyses base on nuclear (ITS) and plastid DNA (matK and rbcL) were conducted to explore the phylogenetic position of the species. The molecular evidence supports C. biflorens as sister to C. rhizomatosum.

Saxifraga viridipetala Z-X. Zhang & Gornall (Saxifragaceae) is described as a new species. Originating from south-western Sichuan province in China, morphological and molecular evidence (based on chloroplast trnL-F and nuclear ITS DNA sequences) indicate that S. viridipetala is closely related to S. gemmipara, in section Ciliatae. The new species can be diagnosed by its narrowly elliptic, pale green petals spotted purple in the proximal 4/5 part.

A New Species

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

A New Species

The genus Minuartia is represented in Turkey by 34 taxa. Some interesting specimens were collected from Antalya province, and examined. These specimens resemble Minuartia meyeri, and M. multinervis from which differ by characters (macro-, and micromorphological) of inflorescence, alar pedicels, petals, sepals, capsules and seeds. Moreover, by using the DNA sequences of the ITS genes, phylogenetic relationships between this collected species, and the related species were investigated. As a result of the evaluation of molecular, and morphological data, we proposed to described the population from Antalya as a new species for the science. A description, pictures, distribution, habitat, and IUCN category are given.

It is herein presented Ruehssia sumiderensis as a new species known only in the Cañón del Sumidero National Park, in Chiapas, Mexico. It is illustrated with a line drawing, live images and SEM photographs of the gynostegium and pollinarium. Morphological and molecular evidence with plastid data (trnL intron and trnL-F intergenic spacer) confirms its position in Ruehssia, a recently proposed genus that includes American Marsdenieae species. It is similar to Marsdenia laxiflora and M. pinetorum due to the basally rounded or truncate leaves, rotate corolla without callous cushions in the sinuses. Two new combinations are also made in Ruehssia, for M. laxiflora and M. pinetorum.

Pseudohydnum brunneiceps is described as a new species from Jiangxi Province, central China. Morphologically, it is characterized by a gelatinous basidiocarps, pilei pale yellowish brown, dark reddish brown to blackish velutinate, spines conical and white, and basidiospores globose to broadly ellipsoidal. Phylogenetic analyses of DNA sequences from partial 28S region and internal transcribed spacer (ITS) also confirm that P. brunneiceps forms an independent lineage within Pseudohydnum. A description, photographs of the fresh basidiomata and line-drawings of the microstructures are provided. In addition, the previous records of P. gelatinosum in China should be re-evaluated by more representative samples by molecular phylogeny.

We have described and illustrated a new species, Bulbophyllum linzhiense (Malaxideae, Epidendroideae, Orchidaceae), from Tibet Autonomous Region in southwest China. The size and overall floral morphology of the new species are similar to those of B. rubrolabellum, a species endemic to Taiwan island on the southeast coast of China, but is different by apart pseudobulbs, lower flowers, ovate-lanceolate bracts, longer pedicel and ovary, yellow-green flower, and lanceolate lateral sepals. A cladistic analysis based on the nuclear (ITS) and plastid (matK, trnL-F, and atpI-atpH) DNA sequences supported the new species is sister to B. rubrolabellum.

A New Species

A new species, Hedysarum cuonanum (Fabaceae, Hedysareae), is described from the eastern Himalaya in China. This new species is similar to H. xizangense, but differs by its lanceolate or narrowly elliptic leaflet blade, ovate or lanceolate bracteole about half the length of calyx tube, acute or obtuse standard apex, and mucronate keel apex. It also resembles H. longigynophorum, but can be distinguished by its leaflet blade with 13–19 secondary veins on each side, abaxial calyx tooth about 1.5 times as long as the adaxial teeth, standard as long as keel, and elliptic or ovate loment article. Phylogenetic analyses based on the nuclear ITS, ETS sequences, and the plastid psbA-trnH, trnC-petN, petN-psbM sequences showed that H. cuonanum is sister to H. xizangense, and the H. cuonanum + H. xizangense clade is then sister to H. longigynophorum.

A New Species

A new species of the genus Caecilia (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. Caecilia pulchraserranasp. nov. is similar to C. degenerata and C. corpulenta but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35. Mitochondrial DNA sequences, including newly sequenced terminals representing two additional, previously unanalyzed species, corroborate the phylogenetic position of the new species within Caecilia and the monophyly of the genus. This analysis also included newly sequenced terminals of Epicrionops aff. parkeri (Rhinatrematidae) and trans-Andean Microcaecilia nicefori (Siphonopidae). Evidence was found for the non-monophyly of the family Siphonopidae and the siphonopid genera Microcaecilia and Siphonops. The implications of these results for caecilian systematics are discussed and the status of the trans-Andean populations of Caecilia degenerata is commented upon.
