DIAGNOSTIC DESCRIPTION
Shrublet 0.2-0.35 m tall, with taproot, fastigiate, erect; branches lateral and sometimes basal (or none), often opposite, strict. Stems reddish-brown, 4-lined, ancipitous and densely gland-dotted when young, eventually terete, cortex exfoliating in strips; internodes 3-20 mm long. Leaves sessile, erect or appressed, ascending or spreading, subimbricate, the upper longer than internodes, the lower shorter, persistent (i.e. deciduous with cortex) or breaking off earlier above base; lamina 6-15 x 1.2-3 mm, linear to narrowly elliptic-oblong, margin revolute, smooth, not cucullate, midrib prominent or not and smooth beneath, paler beneath, and often glaucous above or on both sides, coriaceous; apex subacute, base narrowly cuneate to parallel-sided, free; basal veins 1(3), unbranched, tertiary reticulation absent; laminar glands dense, not prominent or slightly so beneath. Inflorescence (l)3-9-flowered, branching all dichasial/monochasial (or the lowermost pseudo-dichotomous), without subsidiary branches; peduncle and pedicels 2-4 mm long, not incrassate upwards; bracts and bracteoles linear-subulate. Flowers 13-20 mm in diam., stellate. Sepals 3.5-4.2 x 1-1.5 mm, subequal, oblong to lanceolate or narrowly ovate, subacute; veins 5-7, unbranched, all becoming prominent; glands all linear or punctiform in upper 1/3. Petals bright yellow, tinged red outside, 8-14 x 2.5-4 mm, 2-3.5 x sepals, oblanceolate; apiculus obsolete; glands few, punctiform. Stamens c. 40, longest 4-5 mm long, c. 0.6 x petals, fascicles 3, subdistinct. Ovary c. 1.5 x 1 mm, narrowly ellipsoid; styles 3, 3.5-4 mm long, c. 2-2.5 x ovary, spreading; stigmas narrowly to rather broadly capitate. Capsule 4-6 x 2-3 mm, ovoid-cylindric, acute, shortly exceeding sepals. Seeds not seen.
