Mature branches terete to subterete, smooth or minutely striate, glabrous, 6-7 mm in diameter, often red dorsally and green ventrally when fresh; bark brown when fresh, but drying yellowish-, grayish-, or reddish-brown; immature branches and twigs of new growth subterete to bluntiy angled, minutely striate, glabrous, reddish-brown when dry. Petioles terete often flattened adaxially, rugose, (4-)6-15 mm long and (0.7-)1-1.5(-2.5) mm in diameter, glabrous, green suffused with maroon when fresh, but drying reddish-brown. Leaves lanceolate to lance-elliptic, rarely oblanceolate or ovate, (3-)8-12(-18) cm long and 1-4(-6) cm broad, basally rounded, obtuse, cuneate or rarely subtruncate, apically acuminate, olive-tan or silvery-green when dry, glabrous or rardy with a few hairs at base of midrib on upper surface; (3-)5(-7)-plinerved, nerves impressed above or rarely veinlets and outer pair of lateral nerves raised, midrib raised and prominent beneath, lateral nerves raised, prominent to obscure beneath, veinlets slightly raised, usually obscure beneath. Infiorescence (7-)11-16(-20) flowered, cylindric to fusiform in bud; rachis long tapering, cylindric, bluntly angled, minutely striate, viscid, glabrous, 3-6(-9) cm long and 2-5 mm in diameter, pink to pinkish white when fresh. Floral bracts rarely translucent when dry, glabrous, smooth or reddish-papillate abaxially, oblong to oblanceolate, rarely obovate or somewhat spatulate, basally narrowed and truncate, apically rounded to acute, (2-)2.5-4(-5) cm long and 1-2 cm broad, deep violet or maroonish-purple, often appearing black. Pedicels swollen distally, striate or ribbed, glabrous, (6-)9-13(-16) mm long and 0.7-1 (-1.5) mm in diameter, pink to pinkish-white when fresh. Bracteoles lanceolate to linear-lanceolate, rarely ovate, 2-4(-5.5) mm long and 0.6-1 (-2) mm broad, basally slightly auriculate, apically acuminate and glandular callose-thickened distal third, purplish-pink when fresh. Calyx glabrous, (6-)7-11(-13.5) mm long; tube cylindric, coarsely ribbed, (2-)2.5-4(-5.5) mm long and (2.5-)3-6(-6.5) mm in diameter across base, basally apophysate and deeply lobed with lobes straight or flaring outward and extending well below articulation, pinkish-red to purplish at anthesis turning pale green postanthesis; limb cylindric or somewhat spreading, weakly ribbed or minutely papillate, (3.5-)5-8 mm long including lobes, pinkish-red; lobes triangular, 1-2(-2.5) mm long and 2-2.5 mm broad, erect after anthesis, glandular callose thickened without, dark reddish-purple or green; sinus obtuse to broadly rounded. Corolla slightly constricted basally, narrowed to throat, sometimes translucent when dry, (25-)30-38(-45) mm long and 5-8 mm in diameter, pilose with short, white trichomes, tube whitish-purple at constricted base, purple to dark purple above, limb and lobes pale purple; lobes oblong, obtuse, 1.5-2 mm long, strongly reflexed at anthesis. Stamens 24-39 mm long; filaments subglabrous or moderately pilose distally, alternately either 3.5-6 mm or 7.5-14.5 mm long, white; anthers including tubules alternately either 16.5-27.5 mm or 22.5-35.5 mm long, orange; thecae 6-13.5 mm long .
