국표에 없다.

Found in Java, Borneo, Sulawesi and Sumatra in lower montane forests low on tree trunks or on rocks at elevations of 400 to 1600 meters as a very variable, medium sized, hot to cool growing epiphyte or sometime lithophyte with clustered, 20" [50 cm] long, cane-like stems enveloped by many tubular sheaths carrying many elliptic-lanceolate, acute, basally clasping leaves articulate to the leaf bearing sheaths that blooms in the late winter through early summer on a short, single flowered inflorescence that arise between the leaves with only a few wide open flowers opening at any one time.

This species is very similar to D octhochilum but this one has white to cream colored flowers with narrow petals, much reduced rounded side lobes of the lip amd althought he central portion of the lip is papilloose/tubercular, it does not have swollen keels.
