Where it grows wild

Recorded mainly from Thailand, with one Malaysian record. Like related species it grows as a terrestrial herb in seasonal forest; the long tuber suggests loose, deep forest soil. Detailed habitat notes were not found.

Few records carry an elevation; the cooler measured nights suggest some records are from hills.
