Literature cited. MALAYSIA – Pedalaman • Keningau, Apin Apin, 16 km on village road, west, and 2 km walk along Apin Apin river to 610 m (“ 2000 ft ”) elev.; 23 Jan 1993; J. Mood 563 (holo K, iso LYJB, SAN, SAR) .

Identification. Schismatoglottis scintillans most closely approaches S. decipiens A.Hay and S. trusmadiensis by the pistillate flower zone extensively (≥ ½) adnate to the spathe, but it is readily distinguished from both species by the combination of a much longer proportion of this adnation (5/6 of the entire pistillate zone vs. ½), and by scintillating leaf blades. Schismatoglottis scintillans is specifically distinguished from S. decipiens by the staminate flower zone half enclosed (not fully exerted) from the lower spathe, and by lacking a naked interstice between the staminate and pistillate zones. From S. trusmadiensis , S. scintillans is further distinguished by a bullet-shaped appendix being much wider than the top of the staminate flower zone (vs. appendix bluntly conoid, and indistinctly wider than the top of the staminate zone) and by the overall much more compact stature, and ovate-sagittate, variegated, velvety leaf blades (vs. hastate-sagittate, plain glossy green) ( Scherberich and Boyce 2013).

Distribution and ecology. Endemic to Sabah. Known only from the type locality in Keningau, Apin Apin, elevation ca. 610 m (“ 2000 ft ”). Grows terrestrially in very shaded riverine forests on wet alluvial soils, at ca. 600 m elev.
