Ligusticum gongshanense Pu, R. Li & H. Li, a new species of Umbelliferae from western Yunnan, China, is described and illustrated. It is closely similar to L. franchetii H. de Boissieu, but differs by having unbranched and light yellow stem, white petals, and styles shorter than stylopodium.     

Calanthe yaoshanensis sp. nov. (Orchidaceae) from northeastern Yunnan,China

A new species of Orchidaceae, Calanthe yaoshanensis Z. X. Ren & H. Wang from northeastern Yunnan, China, is described and illustrated. It is morphologically similar to C. brevicornu Lindley, from which it differs by having a glabrous column and an elliptical middle lobe with three triangular lamellae. The morphological differences between C. yaoshanensis and related species are discussed. The habitat was investigated and its conservation status was assessed as a ‘Critically Endangered’ (CR).     

Hoya tengchongensis sp. nov. (Apocynaceae,Asclepiadoideae) from Yunnan,China

Hoya tengchongensis, a new species of Apocynaceae, subfamily Asclepiadoideae from Yunnan, China, is described and illustrated. The new species is morphologically similar to Hoya serpens in its creeping habit, bearing small and suborbicular leaves, and adaxially tomentose corolla. However, H. tengchongensis differs from H. serpens in corolla size (ca 7 mm versus ca 12 mm in diam) and corona morphology (corona lobes slightly ascending versus erect).     

Impatiens maculifera sp. nov. (Balsaminaceae) Yunnan,China

Impatiens (Balsaminaceae) is a notoriously difficult genus to study for reasons that include small, remote and endemic areas of occurrence, and difficulty in obtaining well‐dried herbarium specimens and separating and reconstructing floral parts from available dried specimens. Impatiens has also been notoriously difficult when it comes to phylogenetic resolution at the infrageneric level, but a new system with two subgenera (Impatiens and Clavicarpa) was recently proposed by Yu et al. and it has made it easier to classify newly discovered species. Impatiens maculifera, a new species of Balsaminaceae from Malipo County, Yunnan, China described here, is similar to I. parvisepala S.X. Yu & Y.T. Hou in having racemose inflorescences, four lateral sepals, clavate capsules and ellipsoid seeds, but differs in having leaves narrowly oval or with elliptic–lanceolate blades (versus obovate or obovate–lanceolate), obvious petioles (versus leaves subsessile), racemose inflorescence with 8–12 flowers (versus 6–8 flowers), flowers greenish yellow (versus yellow), lateral united petals and lower sepal with dense red spots (versus red spots absent), and dorsal petal with apparent stalk at base (versus unapparent stalk). Morphological characters and molecular phylogenetic analyses of DNA sequences from both nuclear ribosomal and plastid genes show that the new species differs distinctively from I. parvisepala. Furthermore, I. maculifera is distinguished from other Impatiens species based on morphological, micromorphological and palynological evidence, and molecular data.     

Lobatiriccardia yunnanensis,sp. nov. (Metzgeriales,Aneuraceae) from Yunnan,China

Abstract

The genus Lobatiriccardia Furuki is reported as new to China, from the Dulong River valley, Gaoligong Shan range, Yunnan Province and this material is described as a new species endemic to China, Lobatiriccardia yunnanensis Furuki & D.G. Long, the fifth known species in the genus. The differences between the new species and the other members of the genus are enumerated, along with a key to all known species of Lobatiriccardia.

Primula zhui (Primulaceae) sp. nov. from south Yunnan,southwest China

Primula zhui a new species of Primula endemic to the Yunnan Province, China, is described and illustrated. It is morphologically similar to P. intanoensis from Thailand, and P. calyptrata from southeast Yunnan, affiliated to Primula sect. Carolinella (Hemsl.) Pax. However, it is easily distinguished from the Thailand species by its longer corolla tube and distylous flowers, and it differs from the Chinese species by its leaf ovate to ovate‐elliptic blade and distylous flowers.
