Characteristics

Suffrutex 60 cm to 1.3 m high, erect or straggling, branchlets with shiny, tufted hairs from a sessile, scaly base or a slightly raised tubercle, hairs long or short and give the new growth, leaves and calyx a golden hue. Stipules narrowly lanceolate, acuminate, subulate or linear-acute, 2.5-10 mm long, base 0.51.5 mm broad, roughly and sublaxly to densely stellate, incurved in upper portion. Leaves subsessile to shortly petiolate; blade strikingly variable in shape from broadly elliptic to elliptic or oblong-obovate, 10-37 mm long, 6-14 mm broad, acute and mucronate to broadly rounded and mucronate or broadest and toothed at subtruncate apex, roughly and subdensely or densely stellate-pubescent on both surfaces, hairs stiff and golden yellow, scattered among groups of hairs are minute, dark pustules; petiole 1-5 mm long. Inflorescence of short, few-flowered, branched cymes in axils of upper leaves, up to 2.5 cm long; peduncles short, up to 5 mm long, roughly stellate; bracts at base of pedicels subulate, up to 10 mm long, often reaching to top of calyx, roughly stellate, arcuate in upper portion; pedicels 1-2 mm long, roughly stellate. Calyx subcoriaceous with strong ribs, densely pubescent with stellate or tufted hairs from a scaly base, hairs shiny and giving calyx a golden hue, about 8 mm long, lobed in upper third or almost to middle, tube cup-shaped, lobes cuspidate from a deltoid base. Petals yellow, about 10 mm long, oblong in upper half, narrowed into a claw with inrolled margins, apex rounded to subtruncate, recurved, dorsally finely stellate-pubescent in lower two-thirds. Stamens about 4-6 mm long with hyaline, obovate-oblong filaments; anthers about 2.5 mm long, ciliate. Ovary 5-angled, stellate at least on sutures; stipe 0.5-1 mm long; styles about 4 mm long. Capsule about 7 mm long, half exserted from persistent calyx, finely stellate-pubescent between sutures which are coarsely stellate-pubescent.
More
Sub-Erect suffrutex, 0.3-1.5 m high; plant with shiny, tufted hairs from a sessile, scaly base or slightly raised tubercle, rays long or short. Leaves shortly petiolate, variable in shape, usually oblong-obovate, over 15 mm long; roughly and densely, golden-brown stellate-pubescent. Stipules ± subulate, upper portion incurved. Inflorescences of short, few-flowered, branched cymes in axils of upper leaves; peduncles up to 5 mm long; pedicels roughly stellate-pubescent. Flowers ± 10 mm long, yellow. Calyx cupshaped, 5-lobed in upper 1/3, subcoriaceous, strong-ribbed, lobes cuspidate; pubescence golden-brown. Petals longer than calyx, contorted, upper half oblong, narrowed into a claw. Flowering time all year. Fruit a capsule half exserted from persistent calyx.
Coarsely velvety, erect, twiggy shrub to 1.2 m. Leaves densely hairy, oblong to cuneate, subsessile, often scarcely toothed above, stipules and bracts attenuate. Flowers in small, terminal clusters, yellow or orange, calyx golden-velvety.
