Young parts caducous multicellular glandular tomentose; twig apices, cyme, leaf bud, stipule, petiole and leaf nervation beneath densely persistently pale chocolate-brown tomentose; lamina surface beneath white tomentose. Twig to 3.5 mm ø apically, terete, becoming glabrous, smooth to rugulose, uneven; much branched; stipule scars small to obscure. Bud to 12 by 6 mm, ovoid to falcate, subacute. Stipules to 1.2 cm long, linear. Leaves 9-17 by 4-9.5 cm, oblong to obovate; base cordate, acumen to 5 mm long, deltoid; margin revolute; nerves 16-20 pairs, well spaced, curved at the margin, raised beneath, at 60°-70° except at base, frequently with short secondary nerves; tertiary nerves well spaced, scalariform, distinct; midrib prominent, terete beneath, depressed above; petiole 1-2.5 cm long, geniculate. Cyme to 15 cm long, to 3-axillary, subterete, much branched; bracts to 10 by 3.5 mm, lanceolate, acute, sparsely tomentose, caducous. Flower bud to 5 by 2 mm, narrowly ovoid, conical, acute. Calyx lobes densely tomentose outside, glabrescent within, fused at base forming a cup free from the ovary, imbricate; sub-equal, 2 inner slightly more attenuate, obtuse, subacu-minate; 3 outer acute, acuminate. Corolla deep purple, dark yellow at margins, fading to pale red on falling; petals broadly ovate, subacute, becoming reflexed apically, sparsely tomentose on parts exposed in bud. Stamens 25-30 in several verticils; filaments broad at base, tapering abruptly and filiform below the subglobose anthers; appendage to connective c. 3 times length of anther, slender, curved. Ovary ovoid, densely tomentose; style c. 3 times as long as ovary, shortly pubescent in basal half, otherwise glabrous, sometimes trifurcate at apex. Fruit calyx sparsely ashen tomentose; base narrowly cuneate, the lobes united into a to 1 cm deep and wide cup; 2 longer lobes to 13 by 2.7 cm, lanceolate, tapering gradually to the subacute apex, constricted to 7 mm broad at base; 3 shorter lobes to 7.5 by 1.7 cm, similarly shaped, subequal. Nut to 3.2 by 1.5 cm, narrowly ovoid, densely fulvous tomentose, tapering to a to 5 mm long slender style remnant, acute.
