Indigofera vallicola (Fabaceae), a new species from Yunnan, southwest China

Abstract

Indigofera vallicola (Fabaceae), a new species is described and illustrated. This plant is only found from two localities in the central Yunnan Province, southwest China. It is characterized by having the prostrate habit, usually 13–17-foliolate leaves and the relatively small (3–5 mm long) flowers. Morphological comparisons with its closest relatives, I. rigioclada, I. franchetii, I. chaetodonta, and I. henryi are also presented.
