Bucephalandra ultramafica S.Y.Wong & P.C.Boyce View in CoL Figure 3H

Material examined. MALAYSIA – Sandakan • Kinabatangan, Telupit, Gunung Tawai ; 05°35′46″N, 117°04′ 37″E; 18 Dec 2012; M. Lo AR-4094 (holo SAN, iso SAR, SBC, SING) GoogleMaps .

Identification. Bucephalandra ultramafica is unique by the combination of deeply ridged petioles, narrow deep green glossy leaves, and a bullet-shaped appendix. The leaf blades are somewhat reminiscent of those of B. goliath S.Y.Wong & P.C.Boyce , but B. ultramafica never develops the long pendent stems diagnostic of B. goliath , and the spadix appendix and appendix staminodes are of quite different form ( Wong and Boyce 2014).

Distribution and ecology. Endemic to Sabah. Known only from the type locality at Gunung Tawai. Restricted to ultramafic (ultrabasic) riverside rocks under lowland moist forest at ca. 130 m elev.
