Extended description:— Hemiparasitic plant. Haustorium unknown. Monopodial percurrent branching. Stem internodes persistently keeled, 2.3–6.5 cm long, 3.3–5.3 mm diameter in keeled portion, 2.5–4.1 mm diameter in flattened portion; first branching internode 3.6–5.4 cm long, being the same shape as stems, basal cataphylls (2–)3(–5) pairs, basally fused and distally separate, last pair borne up to 1–2.5 cm above the branch base, intercalary cataphylls absent. Leaves 10–19 × 2.5–5 cm, coriaceous, lanceolate, subsessile, apex acute and distally rounded, base tapering to a winged indistinct petiole.
