Schismatoglottis gillianiae
Rather small pendent to suberect usually rheophytic herb to c. 40 cm long. Stem branched and tuft-forming, rooting among and below the leaf bases. Leaves several together; petiole 2.5–12.5 cm long, pale to olive green, sometimes tinged red, sheathing in the lower 1.5–2 cm, the sheath extended into a free tapering ligular portion to 3.5 cm long, occasionally minutely and densely hairy abaxially, usually glabrous; blade narrowly oblanceolate, 1.5–3 times longer than the petiole, 9–35 cm long, 3–3.5 cm wide, the base decurrent, the apex acuminate for 1.5–4 cm; midrib not or hardly raised on either surface (dry), drying conspicuous dark brown abaxially; primary lateral veins 4–8 on each side, diverging at c. 30°, slender and not raised but conspicuously dark abaxially, adaxially somewhat obscure, alternating with more slender interprimary veins; secondary venation fine and rather dense, arising from the midrib. Inflorescence solitary; peduncle very short, 2–3.5 cm long, concealed by leaf and cataphyll bases (elongating in fruit). Spathe 3–6 cm long, cream to white,
sometimes flushed pink in the lower part; lower spathe narrowly ovoid, 1.5–2.5 cm long; limb lanceolate, caducous, 2.5–4.5 cm long. Spadix sessile, cream, somewhat shorter than the spathe, more or less subcylindric throughout (dry); female zone 1–2 cm long, partly adnate to the spathe dorsally; interpistillar and basal staminodes absent; ovaries squat, 1 × 1 mm; stigma sessile, discoid, slightly wider than ovary, c. 1.1 mm diam., papillate; sterile interstice 3.4 mm long narrowly obconoid, composed of somewhat lax oblong to somewhat polygonal staminodes; male zone c. 1–1.3 cm long; stamens polygonal-columnar, truncate, densely arranged, 1–1.5 mm diam.; appendix 1.2–3 cm long, tapering, distally somewhat flattened, composed of very densely arranged trapezoid to polygonal, centrally impressed staminodes. Fruiting peduncle to 8 cm; fruiting spathe ovoid, c. 3.5 cm long.
Malesia: endemic to Borneo (Brunei), with one doubtful record from Sarawak (see Notes).
Rheophytic on rocks and in muddy stream banks, occasionally on forestfloor; on Setap shales and Belait series sediments,
