Oreocharispolyneura, a new species of Gesneriaceae from southern Yunnan, China.

Oreocharispolyneura, a new species from southern Yunnan, China, is described and illustrated. It is morphologically similar to O.rhytidophylla by having more obvious lateral veins forming a crosslinked network on the adaxial surface of leaf blades, but can be distinguished by having more lateral veins (12-15 pairs vs. 7-9 pairs) of leaf blades, shorter corolla tubes (the length ratio of corolla tube to corolla lobes = 1.2-2.9 vs. 3.4-6) and shorter pistils (6-8 mm long vs. 27-30 mm long). In addition, a detailed morphological description, a photographic illustration, the distribution and phenology of the new species are presented.

Complete plastome sequence of Aspidopterys obcordata (Malpighiaceae), a traditional Dai medicinal plant from Xishuangbanna, Yunnan, China.

We reported the first complete plastid genome of Aspidopterys (Malpighiaceae) in this study. The complete plastome of Aspidopterys obcordata is 160,453 bp in length with a base composition of A (31.4%), G (18.5%), C (18.2%), and T (32.0%). Structurally, the genome contains two short inverted repeats (26,905 bp for each), which are separated by a large single copy region (88,491 bp) and a small single copy region (18,152 bp). The plastome contained 113 unique genes, including 79 protein-coding genes, 30 transfer RNAs, and 4 ribosomal RNAs. Phylogenetic analyses showed that A. obcordata was sister to Bunchosia argentea in the monophyletic Malpighiaceae. This study provided a high-quality plastome sequence for future studies in Aspidopterys, as well as Malpighiaceae.
