SUMMARY
Epiphytic vine; internodes elongated and slender, 9– 11 cm long, 3 mm diam. upon drying; cataphylls membranaceous, persistent, 3.5–5 cm long, drying reddish brown. Leaves with petiole terete, slender, rising at 50–70° angle from the caudex, 3.5–7 cm long, c. 2 mm diam. upon drying; blade narrowly ovate-lanceolate, acuminate at apex, rounded at base, 9.5–14.5 cm long, 3.9–5.2 cm wide, averaging 12 × 4.4 cm, 2.4–3 × longer than wide, 2–3.3 × as long as petiole, subcoriaceous, dark green and semiglossy above, light green and semiglossy (drying glossy) with glandular punctuations below, the margin slightly inrolled downwards when dried; midrib moderately raised and slightly paler above, sharply raised and paler below; primary lateral veins 4–5 pairs, rising at 45–75° angle, flat above and moderately raised below, concolorous; collective veins arising from the 1st pair of basal veins, 3–8 mm from margin; basal veins consisting of one main pair turning into the collective veins, and sometimes a diffuse 2nd pair near the base. Inflorescences several, rising at 40–70° angle from each node along the stem; peduncle terete, thinner and much longer than petioles, 9–10 cm long, c. 1 mm diam.; spathe membranaceous, lanceolate, 2.5–3 cm long, c. 6 mm wide, becoming reflexed then caducous in fruit, reddish; spadix reddish, stipitate for 3 mm, thin and cylindrical when young, becoming thicker and knotty at maturity, 2.5–3 cm long, 2–3 mm diam. when young, growing to 7 mm diam. in fruit. Flowers 2.2–2.4 mm long and wide, 3 visible per spiral; tepals drying dark yellowbrown, smooth except for an occasional large pale cellular inclusion, lateral tepals 0.5–0.7 mm wide, outer margins 2–3 sided, inner margins rounded, scarious.
