Morphology General Habit
A mat forming perennial herb or suffrutex with prostrate, woody, leafless, glabrous, branched main stem which emits erect or ascending branches.
Morphology Branches
Branches inserted 0·7-3 cm. apart, up to 11 cm. long and 0·5 cm. in diam., subquadrangular or cylindric, often 2-forked or sometimes simple, with brown-scarious ± fissured bark, leafless or, when simple, leafy upwards, glabrescent, with the scars of the fallen leaves ring-shaped and pale, rather visible but not prominent; branchlets of the year usually the only leafy, 1·5-6 cm. long, herbaceous, grey or green-yellowish, hispidulous, the hairs short, whitish; internodes 0·2-1·5 cm., all ± shorter than the leaves, the apical of the leafy branchlets the shortest ones.
Morphology Leaves
Leaves 1·3-4·5 cm. long and 2-10 mm. broad, linear, 3-gonous or semiterete (convex beneath and canaliculate above in the living state), obtuse at the apex, entire, slightly attenuate towards the base, sessile and very shortly connate, not ciliate at the obtuse margins, ± covered with whitish, short, appressed or subspreading, subretrorse hairs, fleshy in living state, rigid on drying, erect or erect-spreading, somewhat arched; leaves of the old branches falling off together with the connate base.
Morphology Reproductive morphology Flowers
Flowers 5-merous, disposed in dense cymes, forming 4-7 branched corymb-like, terminal inflorescences, 2·3 cm. long and 3·5-5 cm. in diam.; peduncule 7·5-9 cm. long, slender, hispidulous, with 2-3 pairs of opposite bracts; pedicels up to 1·5 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx 2·5 mm. long, densely hispidulous by whitish hairs; sepals c. 2 x 1 mm., oblong-triangular, convex, fleshy.
Morphology Reproductive morphology Flowers Corolla
Corolla 3·25-4·5 mm. long, stellate, white in living state, dark-brown on drying and forming a strong contrast in colour with the whitish calyx; petals 1·5-2·25 mm. broad, obovate, rounded at the top and with a subapical small mucro on the outside, smooth or nearly so, reflexed.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments ± 2·75 mm. long.
Morphology Reproductive morphology Fruits
Follicles 2·5-3·5 mm. long, rather attenuate, with distinct, divergent styles and apical stigmas.
