Identification. Schismatoglottis ferruginea is similar to Schismatoglottis barbata Engl. (Sarawak) in the coarsely hairy petiole and the leaf shape tending to be widest distal to midway along the midrib. Both species differs in the not tufted habit, larger size, the distinctly cordate leaf blade base, the hairy and relatively long peduncle, the slender hairy spathe constricted near the base and, presumably from the shape of the spathe, the more or narrowly tapering spadix (Hay and Yuzammi 2000).

Distribution and ecology. Endemic to Sabah. Lithophytic in sandstone crevices by riverbanks or in secondary forest near streams at low elevation. On boulders and terrestrial on rather dry slopes in mixed lowland forest at low elevations.
