﻿AbstractLiparistianchiensis(Orchidaceae,Epidendroideae), a new species from Wenxian County, Gansu Province, China, is described and illustrated, based on morphological characters.Liparistianchiensisis morphologically similar toL.damingshanensis,L.paulianaandL.mengziensiswith erect, lax flowered-inflorescences, small persistent floral bracts, small greenish-purple flowers, spreading sepals, free reflexed and linear petals, a lip with 2 calli near the base and an arcuate column.Liparistianchiensisdiffers fromL.paulianaby the single and much smaller leaf, shorter sepals and petals, smaller and reflexed oblong lip. It differs fromL.mengziensisby having fewer and larger flowers and not connate lip apex. The novelty mostly resemblesL.damingshanensis, but can be readily identified by having longer sepals and a reflexed oblong lip.Liparistianchiensisonly occurs in evergreen broad-leaved forest around a mountain lake in Wenxian County, Gansu Province, China.
