Description

Pittosporum qibainongense Y.S.Huang, Yan Liu & Y.F.Deng, a new species of Pittosporaceae, is described and illustrated from karst areas of southwest China. It is morphologically similar to P. trigonocarpum in having leaves clustered at the branchlet apex, blades obovate or oblong-lanceolate, terminal umbellate inflorescences, and capsules dehiscing by three valves, but it can be easily distinguished from the latter by its leaf margins strongly revolute when dry, lateral veins conspicuous on both surfaces, placentas at the lower middle part, and capsules usually multiple, ovate or obovoid, and glabrous. Photographs of this new species, as well as a table and a key to distinguish it from the similar species, are provided. The threatened status of the new species is also assessed.
