Abstract

Schoenorchis kembangleutik Yudistira & Mustaqim described here as new to science is an orchid species currently considered endemic to West Java. It is similar to S. pachyachris (J.J.Sm.) J.J.Sm. from Sumatra and Java but differs in having flowers with midlobe of labellum orbicular (vs oblong) with horizontal and rounded (vs pointing upwards and tapering to a point) apex, the labellum side lobes white, uncinate and retrorse at the apex (vs yellow, straight and erect at apex), and in having shorter spurs with straight base (2 vs 4 mm long, with geniculate base). A morphological description, notes on distribution, habitat and ecology, an illustration, photographs and a key to the five species of Schoenorchis of Java are provided.
