A sparsely hairy, leafy climber, 1 m or more high. Stem twining, branching; nodes with a distinct ring of simple hairs; internodes 40-110 mm long, c.2 mm diam., unifariously puberulous. Leaves herbaceous, spreading; petiole 13-25 mm long, terete, pubescent all around but more so in adaxial channel; lamina 40-65 x 13-25 mm, narrowly elongated deltoid-cordate or cordate-lanceolate, base deeply cordate, apex acuminate or acute; with a broad subtruncate sinus between the semiorbicular incurved or overlapping basal lobes; sparsely and rather minutely pubescent on both sides, margin entire, ciliolate. Inflorescence long, slender, branched, paniculate cymes up to 70 mm long; bracts subulate, c.2 mm long, glabrous; peduncle 25-60 mm long, c.1 mm diam., unifariously puberulous, branching at the node or at a distance, bearing 2(-3) close pseudoumbels with or without a third sessile one at the base, successive fascicles ± touching; pseudoumbels 8-24-flowered, somewhat flat-topped, many flowers opening simultaneously; pedicels long and slender, 10-20 mm, c.0.3 mm diam., all more or less incurved, glabrous. Sepals linear-subulate or subulate-lanceolate, 2-3 x c.0.5 mm at base, glabrous. Corolla 14-16 mm long, straight, glabrous throughout; tube slightly globose-inflated at base, 6-8 mm long x 2-3.5 mm diam.; exterior apparently pale yellowish or whitish; lobes attenuate-linear, 6-8 x 0.6-0.8 mm wide at base, erect-connivent, connate at apex to form a ± oblong-ellipsoid cage-like structure c.3-4 mm diam., apparently dark brown. Corona ± cupular, c.1.6 x 1.6 mm, shortly stipitate, biseriate, whitish-translucent, glabrous throughout; outer lobes narrowly deltoid or deltoid-ovate, obtuse, subtruncate or minutely notched at the apex, forming 5 large pockets, radiately spreading c.0.7 x 0.4 mm broad at base, adaxially concave-channelled; inner lobes dorsiventrally compressed, linear or linear-obtuse, acute or obtuse, c.0.4 x c.0.3 mm, ± as long as anthers and closely applied to their backs; guide rails c.250 ?m long. Pollinarium: pollinia 260 x 170 ?m, elliptic-oblong with an acute pellucid margin at apex: corpusculum elliptic, 17 x 60 ?m. Carpels glabrous. Follicles and seed unknown.
