A sparsely hairy, leafy, erect or ascending, tufted herb to 1 m high. Stem sparsely branching, stout in older parts, dry stems hollow at centre; nodes with a distinct ring of long whitish/brownish-translucent multicellur hairs; internodes 40-70(-125) mm long, 1.5-5 mm diam., unifariously puberulous, hairs minute, simple, whitish-translucent, reflexed. Leaves herbaceous, spreading; petiole (8-)20-40 mm long, terete, pubescent within and along rims of adaxial channel, with orange-brown glands on adaxial side where the lamina joins the petiole; lamina (15-)30-60(-70) x 20-60(-70) mm, broadly ovate, base deeply cordate, apex shortly acuminate or acute; with a broad subtruncate sinus between the semiorbicular incurved or overlapping basal lobes; sparsely and rather minutely pubescent on both sides or glabrous, margin entire, ciliolate. Inflorescence of short, unbranched, mostly sessile or subsessile umbellate cymes up to 30 mm long, sometimes one peduncle produced and a second subsessile one from the same point; bracts linear-subulate, 1.5-2 mm long, ± glabrous; peduncle 0-20 mm long, 1-1.5 mm diam., glabrous to sparsely puberulous, pseudoumbels, 3-6(-10)-flowered; in bud, flowers cylindric, attenuate-acute, convolute in apical half; pedicels 5-10(-15) mm, long, slender, glabrous. Sepals linear-lanceolate, 3-4 x 0.7-1 mm at base, glabrous or sparsely pubescent. Corolla (11-)15-20 mm long, straight, glabrous throughout; tube campanulate, 4-5 mm long x 5-7 mm diam.; exterior cream, interior greenish-cream; lobes linear-lanceolate, (7-)8-15 x 2-3 mm wide at base, mostly free, occasionally connate at apex to form a globose cage-like structure. Corona ± oblong-elliptic, c.1.6 x 1.2 mm, shortly stipitate, biseriate but appearing ± uniseriate, yellowish, glabrous throughout; outer lobes forming very short open pockets between the inner lobes and confluent with them, emarginate with margins of notch somewhat thickened and recurved to give a V-shape at centre with ‘teeth’/lobules ± face-to-face; inner lobes incumbent erect over the staminal column, dorsiventrally compressed, linear-oblong, c.1.3 x 0.2 mm in middle, apex obtuse or emarginate, only closely applied to backs of anthers in basal area; guide rails c.200 ?m long, well exposed. Pollinarium: pollinia c.300 x 240 ?m, oblong with a truncate pellucid crest extending across whole breadth of pollinium hence giving them a distinct D-shape; corpusclum linear without distinct slit at base, c. 210 x 70 ?m; caudicles arising from base of corpusculum and attached to bases of the ventral sides of pollinia. Carpels glabrous. Follicles paired acutely divergent, cylindrical, apically tapering, 75-100 x 3-4 mm diam. at centre with slight constrictions at intervals of 5-7 mm when mature; seed dorsiventrally compressed, elliptic-oblong, c.7 x 2 mm, dark brown or blackish with a c.0.3 mm wide paler margin; coma c.17 mm long.

Perennial herb with woody rootstock producing long, subsucculent roots. Stems tufted, erect or somewhat twining, up to 0.6 m or more high, sparsely branched, with internodes 40-50 mm long, unifariously pubescent and with long hairs at nodes. Leaves: petioles 20-40 mm long, pilose on upper surface; blade cordate-ovate, up to 50(-70) mm long and broad, acuminate, glabrescent, ciliate on margin. Flowers many, cymose in extra-axillary racemes; pedicels filiform, 15-30 mm long. Sepals linear-lanceolate, ±4 mm long, glabrous. Corolla 18-20 mm long, glabrous; tube campanulate, 5 mm long, about 6 mm diam.; lobes linear-lanceolate, 13-15 mm long, cohering at the delicate tips which readily become free on maturity. Corona appearing uniseriate, with 5 small pockets with outer margin deeply divided, confluent laterally with base of inner lobes; inner lobes linear-oblong, erect, obtuse or emarginate, ±2 mm long, greatly exceeding staminal column. Follicles slender, subcylindric, up to 100 mm long, slightly constricted at intervals of 6-7 mm.
Twining perennial herb. Corolla campanulate, 18-20 mm long, tube shorter than lobes, lobes mostly free at tips at maturity. Inner corona lobes greatly exceeding staminal column. Flowers cream.
