Characteristics

Shrublet, 20-60 cm tall, sometimes up to 1 m tall, branched from near the base, erect or, when browsed, forming a low bushy plant, main stem woody; branchlets tomentose, the grey tomentum intermixed with light brown, clustered, villose hairs. Stipules subulate, tomentose, up to 14 cm long. Leaves pubescent above with subappressed, long, single hairs or very occasionally 2 or 3 hairs from the same base, greyish-stellate-tomentose beneath intermixed with clustered light brown hairs, especially on the nerves, ovate-oblong to ovate-lanceolate, up to 10 cm long and 4 cm broad, margins shallowly dentate, sometimes obscurely so; petiole 0.7-1.5 cm long. Inflorescence axillary, peduncle rigid, up to 5 cm long, usually 2-flowered at the apex, pedicels up to 1 cm long. Epicalyx-bracts, broadly ovate, acuminate, cuspidate at the apex, cordate at the base, usually slightly longer than the calyx and petals, densely tomentose to villose-tomentose on both sides, up to 2.5 cm long, 1.3 cm broad, usually longer than the calyx. Calyx lobed almost to the base, lobes ovate-lanceolate, up to 1.5 cm long, hirsute-hispid without. Petals about as long as the calyx, broadest at the apex, pale yellow, fading brownish yellow. Stamens 5, alternating with 5 linear-ligulate staminodes which are about twice as long as the stamens. Ovary subglobose densely [as “densly”] villose; style about 3-5 mm long, branches 1.75-2 mm long; ovules 4-5 in a cell. Capsule hispid with tufted hairs.
