Identification. Schismatoglottis decipiens is closely allied to Schismatoglottis trivittata Hallier , Schismatoglottis motleyana Engl. and other allied species with hapaxanthic stems, fully attached leaf sheaths and caducous spathe limbs. Schismatoglottis decipiens has a unique combination of features in the staminate zone exserted from the lower spathe chamber, the conspicuous partly naked interstice, the broad flat connective of the stamens, the appendix barely and not abruptly wider than the staminate zone, and the leaves with rather few primary lateral veins and a large number of secondary veins arising from them (a characteristic generally, though not entirely, otherwise associated with species with larger leaves) ( Hay and Yuzammi 2000).

Distribution and ecology. Schismatoglottis decipiens is endemic to Sabah. Terrestrial on slopes and rocky sites in forest over ultramafic substrate at elevations of ca. 100– 400 m.
