Leaves usually subsessile, amplexicaul, drying olive brown or dark green, oval to semiorbicular, (5-)8-16(-18) cm long, (4-)5.5-10(-13) cm wide, basally cordate with the basal lobes rounded, usually imbricate, apically obtuse to broadly rounded, rarely bluntly cuspidate; pin-nately veined, the midrib impressed above, raised and conspicuous beneath, lateral nerves usually raised on both the surfaces, anastomosing to form a weak, collective marginal nerve, the veinlets slightly raised and obscure to conspicu-ous; petioles subterete, rugose, to 5 mm long. Inflorescence 1(-3) rachises per axil, the largest rachis rarely once branched at the base, 10-27(-60)-flowered, the rachis terete to bluntly angled, swollen at each floral node, 2-9(-20) cm long and 1-2 mm in diameter at anthesis, increasing to 3 mm diameter post-anthesis, pinkish green at anthesis, later turning purplish; floral bracts smooth or becoming ribbed after drying, elliptic to ovate lanceolate, rarely subor-bicular, basally narrowed and somewhat auriculate, apically acute, (10-)11-16 (-20) mm long, (5-) 7-10 (-17) mm wide, dark pink to red, marginally scarious and glandular fimbriate, ascending at anthesis but later spreading or perpendicular to the rachis; pedicels minutely striate or rugose, (2-)4-9(-11) mm long, 0.5-1 mm in diameter, pinkish green at anthesis but later turning purplish; bracteoles oblong to lanceolate, (1-) 3-4 (-7) mm long, (0.5-) 1-2.5 (-4) mm wide, basally slightly auriculate, apically rounded, marginally glandular fimbriate, dark pink. Flowers with the calyx (4.5-)6-8(-10) mm long, the tube hemispheric, basally not enlarged, smooth or minutely muricate, (1.5-)2-3.5(-6.5) mm long, 2.5-6 mm in diameter, purplish green, the limb campanulate, coriaceous, (2.5-)4-5(-5.5) mm long including the lobes, pale green, the lobes reniform, broadly ovate, rarely oblong, imbricate, (1.5-)2-3(-4) mm long, (1.5-)3(-4.5) mm broad, glandular fimbriate, whitish green, flaring at anthesis, later conni-vent and tightly curling around the base of the style; corolla cylindric or bottle-shaped, narrowed at the throat, (7-)8-10(-12) mm long, 4-6.5 mm in diameter at the widest part, white at the base, purplish black in the basal 1/4, the mid-section green, the limb white, the lobes oblong, obtuse, 2-2.5 mm long, white; stamens 7-8.5 mm long, the filaments white, alternately 2-3 mm and 3.5-4 mm long, with a few scattered distal hairs, the anthers orange including tubules al-ternately 4.5-6.5 mm and 5.5-7 mm long, the thecae 2-4 mm long; style 7-8.5 mm long, distally flaring. Berry 9 mm in diameter.
