Campylotropis luquanensis (Fabaceae: Papilionoideae), a new species from Southwest China

Campylotropis luquanensis, a new species from Yunnan and Sichuan, Southwest China, is described and illustrated. It is morphologically similar to C. grandifolia and C. henryi, but it can be distinguished by having smaller stipules, abaxially sparsely pubescent obovate to obcordate leaflets, shorter inflorescences, and legume with obvious net-veins. Moreover, C. luquanensis is distinguished by usually with 2–4 axillary racemes densely clustered on the second-year brachyhlasts, and by its flowering before leaves. Information of this new species including distribution, habitat, phenology and etymology is also provided.
