Schismatoglottis ferruginea Merr.

Small herb to c. 20 cm tall. Stem somewhat elongate, suberect, c. 5 mm diam. With internodes c. 5 mm long, pleionanthic. Leaves few together (c. 4); petiole shorter than the blade, 5–9 cm long, thickly clothed in coarse white (drying rust) multicellular hairs to 4 mm long, sheathing in the lower ¼–⅓, the sheath fully attached save for a bluntly bilobed ligular extension c. 5 mm long; blade rather variable in size and shape on any plant, but some leaves always and characteristically (narrowly) obovate (some elliptic or narrowly oblong-ovate) 10–16 cm long × 4–6 cm wide, mid-green adaxially, abaxially paler, the base narrowly but distinctly cordate with the posterior lobes reduced to auricles c. 0.5–1 cm long and sometimes overlapping each other, the tip acute and shortly acuminate for c. 1 cm; abaxial side of blade densely hairy on the midrib and progressively more sparsely hairy on the higher order venation with few hairs between the veins; adaxial side and margins completely glabrous; midrib more or less flush with the lamina (dry); 6–9 primary lateral veins on each side diverging at 45–60°, alternating with lesser interprimaries; secondary veins not prominent, mostly arising from the midrib, a few from the bases of the primary veins; tertiary venation forming a rather faint tessellate reticulum abaxially. Inflorescence solitary, subtended by an abaxially hairy lanceolate cataphyll to 4 cm long; peduncle slender, hairy, weak, c. 4 cm long. Spathe 5 cm long; lower spathe ovoid, c. 8 mm long, hairy, differentiated from the limb by a clear but rather weak constriction; limb lanceolate, 3.5 cm long, deciduous at the constriction, very slightly reflexed, with scattered hairs abaxially, especially along the midline. Spadix details unknown. Infructescence unknown.
