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.

Diagnosis: Indigofera vallicola is most similar to I. rigioclada Craib by sharing the procumbent habit, relatively small leaves and the similar flower shape, but it clearly differs from the latter by its usually 13–17-foliolate, flowers 3–5 mm long, calyx teeth triangular-lanceolate, and legumes 1–2 mm in diameter.
Etymology: The specific epithet is taken from the Latin “vallis” (valley) and the suffix “-cola” (dweller), referring to the habitat where the new species is found.
