A new orchid species, Bulbophyllum versicolor (Malaxideae, Epidendroideae, Orchidaceae), from Malipo, Yunnan, China, is described and illustrated here. Detailed morphological study indicates that B. versicolor is similar to B. japonicum, but it differs in the shape and size of leaf and flower and flower colour. Molecular analyses based on the nuclear ribosomal DNA (nrITS) and plastid DNA (matK, atpI-atpH and trnL-F) reveal that B. versicolor is a new species and genetically similar to B. japonicum.

A new orchid species, Dendrobium yongjiaense, from Zhejiang, China, is described and illustrated here. Detailed morphological study indicates that D. yongjiaense is similar to D. monticola and D. strongylanthum, but it differs in the shape and size of leaf, flower size, and a mid-lobe of the lip with densly distinct crystalline papillae and wrinkled 3–5 crest lines in middle. Molecular phylogeny analyses based on the nrITS and plastid DNA (matK and trnL-F) reveal that D. yongjiaense is a member of sect. Stachyobium, and genetically similar to D. monticola.

A new orchid, Calanthe tsiana, is described from southeastern Yunnan, China, based on morphological and DNA evidence. In morphological comparisons, C. tsiana is similar to C. arisanensis, but it differs in having subspatulate petals and falcate-obovate lateral lobes of lip with one ridge on the disk. The phylogenetic analyses based on nuclear ribosomal ITS and plastid DNA (rbcL, matK and trnL-trnF) place C. tsiana with C. arisanensis as sister species and support C. tsiana as a new species.

This study describes a new orchid species, Cymbidium motuoense, from Xizang, China based on morphological and molecular analyses. Several unique morphological features distinguish this new orchid from all other species of Cymbidium. Based on its morphology, this orchid is similar to C. tracyanum but differs in its yellow-green flower with dark purple-red spots on the veins, oblong-elliptic sepals, side lobes of the lip with reddish brown hairs along the veins and disc with three purple-red lamellae. Phylogenetic analyses based on plastid DNA (matK and rbcL) supported C. motuoense as a new species. However, the low support in nuclear ribosomal ITS tree provide the possibility that the new orchid may be a natural hybrid of C. tracyanum and C. iridioides or another closely related species.

Abstract—Isodon hsiwenii, a new species from Yunnan in Southwest China, is here described and illustrated. In order to clarify the phylogenetic placement of the new species within Isodon, Bayesian and maximum likelihood analyses based on two nuclear ribosomal DNA regions and four plastid DNA regions for 71 Asian Isodon species were conducted. The results indicate that I. hsiwenii is a member of the largest and poorly resolved Clade III, as sister species of I. hirtellus. Isodon hsiwenii can be distinguished from I. hirtellus by various morphological differences.

Piper jianfenglingense, which was collected in the Jianfengling National Natural Reserve, Hainan Island, China, is described and illustrated herein. Morphologically it is similar to P. mutabile, from which it differs in having sparsely pubescent petioles, vaginate at base only; rachises glabrous; floral bracts adnate to rachis, margin partially hidden; stamens 2, with considerably longer filaments, these caducous when anthers mature; stigmas ovoid, apex acute; berries and seeds ellipsoid. Molecular analyses based on the ITS marker of nuclear ribosomal DNA strongly support P. jianfenglingense as a new species in the genus Piper, most closely related to P. macropodum.

We conducted morphological and molecular analyses to describe a new species of Piperaceae, Piper semi-transparens, which was observed in Hainan, Guangdong and Guangxi Provinces, China. Detailed morphological comparisons between the newly discovered species and other members of Piper indicate that Piper semi-transparens is similar to P. bonii and P. bonii var. macrophyllum, from which it differs in having glabrous leaf blades; stem densely short and unbranched pubescent when young, glabrous when mature; veins 5(–7); stamens 2; stigmas 3, rarely 4; spikes color white when mature; floral bracts glabrous; pericarp white and semi-transparent. Molecular analyses based on the ITS marker of nuclear ribosomal DNA strongly support that P. semi-transparens is a new species in the genus Piper, most closely related to P. bonii and P. bonii var. macrophyllum.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

In this study, we describe a new orchid species, Goodyera malipoensis, from Yunnan, China. We have performed morphological and molecular analyses on this new species. A detailed comparison between the newly discovered orchid and other members of Goodyera was conducted. The new plant is characterized by having a dense brownish green pubescence on the peduncle. Its ovate-lanceolate petal is unique in Goodyera genus. The hypochile is deeply concave-saccate, and inside there are two papillose rows on each side. These features distinguish the new orchid from all other known species of Goodyera. The molecular study based on nuclear ribosomal ITS sequence data and morphological differences support G. malipoensis as a distinct species.

After examining morphological, molecular and genome-size evidence, we describe and illustrate a new orchid species, Apostasia fogangica, from Guangdong, China. Morphological comparisons indicate that A. fogangica is similar to A. shenzhenica, although the habit, leaves, inflorescences and fruit shapes and sizes differ. Comparison of the genome sizes in Apostasioideae show that A. fogangica is 1C=0.952 pg, which is double the size of A. shenzhenica but close to that of A. wallichii. Molecular analyses from combined nuclear and plastid datasets (ITS, matK and trnL-F) indicate that A. fogangica is sister to A. nipponica plus A. shenzhenica. The morphological, genome-size and molecular evidence support the hypothesis that A. fogangica is a new species.

Peucedanum huangshanense, a new species discovered in Anhui, China, is illustrated and described. Detailed morphological comparisons have showed that it is similar to P. praeruptorum but differs from the latter by having larger compound umbels (5–14 cm across), rays up to 25, and long-ovoid mericarps with lateral ribs narrowly winged. To explore the phylogenetic position of this species, nuclear ribosomal DNA internal transcribed spacer (ITS) region was sequenced for P. huangshanense and P. praeruptorum collected in different places. The morphological and molecular evidences support the hypothesis that P. huangshanense is a new distinct species.
