Suffrutex, 15-90 cm tall, branching from base; branches ascending, leaves and stipules usually neatly arranged in ranks (imbricate), pubescence not conspicuous, consisting of minute fringed scales or stellate hairs, grouped hairs from a tubercled base also sometimes present. Stipules green, subcoriaceous, 7-10 mm long, about 3 mm broad, more or less oblong or oblong-elliptic, sometimes slightly oblique and slightly narrowed towards base, mucronate or bi-mucronate. Leaves subsessile, lettuce-green, subcoriaceous, broadest at apex narrowing into a petiolelike base, plicate, apex rounded and emarginate with a recurved mucro or more or less truncate with 2 or more lobes, rough with minute, fringed scales and often minute, stellate hairs on margin, margin sometimes with a narrow red-brown rim. Inflorescence of 1-2-flowered cymes at apex of leafy branchlets and in axils of upper leaves; peduncle suberect, 5-12 mm long, with stipule-like bracts at base; pedicels cernuous, 2-3 mm long, with 3 narrow, 4-5 mm long bracteoles at base. Calyx often suffused or mottled with red, campanulate, rough with minute stellate scales and on margins with a few short hairs from a tubercled base, 6-9 mm long, somewhat 5-10-angled, 5-lobed; lobes about 4 mm long, broadly oblong, shortly acuminate and mucronate, sinuses narrow. Petals lemon-yellow, strongly twisted, shortly exserted from calyx, about 10 mm long, blade broadly oblong, contracted below middle into a claw with infolded margins and minute stellate hairs on edges of claw. Stamens about 5 mm long; filaments hyaline, oblong; anthers 2.5 mm long, ciliate. Ovary 3-4 mm long, 2.5-3.5 mm broad, 5-lobed, stellate-tomentose; stipe 0.5 mm long; styles 4 mm long.
