Suffrutex, stems many, somewhat flexible, decumbent, up to 1.5 m long, bright green to glaucous, striate, appearing smooth but often pubescent with stellate or tufted hairs, the hairs short or long, few in a tuft and bulbous-based, branched especially in upper parts; branchlets subherbaceous, secund, ascending, sometimes sparsely stellate-pubescent, glabrescent or with minute gland-tipped hairs, towards the apex. Stipules linear to filiform from a broad base, small, about 4 mm long, early caducous. Leaves sparse, petiolate; blade discolorous, more or less oblong, from narrowly to broadly so, sometimes ovate-oblong and rarely slightly obovate-oblong, 12-50 mm long, 3-28 mm broad, upper surface subdensely to sparsely and minutely stellate-pubescent, glabrescent, nerves impressed, lower surface whitish stellate-tomentose, sometimes thinly so, nerves prominent, margins shallowly to deeply crenate, sometimes lobate-crenate; petiole 3-20 mm long, stellate-pubescent, densely so in contrast to the subglabrous branches. Inflorescence ascending, terminal on branches and branchlets, forming lax paniculate or racemous cymes; peduncles 10-60 mm long; bracts united, about 4 mm long, bracteoles filiform or narrowly lanceolate, 1.5-5 mm long, all caducous; pedicels 3-6 mm long, glabrous, stellate-pubescent or with some tufted hairs, sometimes gland-tipped hairs are present. Calyx 6-8 mm long, lobed to about midway, finely stellate-pubescent, the rays long or short and with black, gland-tipped hairs intermixed, lobes triangular, sinuses fairly wide. Petals yellow, fading orange, 8-10 mm long, upper portion suborbicular, narrowed just above middle into a claw with inrolled margins which are obscurely ciliate. Stamens about 7 mm long; filaments hyaline, oblong-cuneate, 4.5 mm long; anthers ciliate, 3.5 mm long, overlapping filaments and base. Ovary 2.5 mm long, stellate-pubescent, especially densely at apex where hairs are longer; stipe 1 mm long; styles 4.5 mm long, minutely and sparsely hairy in lower portion. Capsule subglobose, exserted from persistent calyx, 5-lobed, shortly 5-umboned, finely stellate-pubescent, more coarsly so on keel of lobes, up to 7 mm long.
