Characteristics

A rounded, compact, much branched shrublet, 40-100 cm high, with short, stout, erect stem (up to c. 1.5 cm thick) and robust, ascending branches. Young branches yellowish, glabrous or faintly puberulent; soon defoliated, brown, and marked with conspicuous leaf-scars forming a reticulate pattern; finally dark ash-grey. Leaves rather densely set, patent to erecto-patent, loosely imbricated, glabrous, rather thick and coriaceous; petiole c. 1 mm long, more or less appressed, yellowish; blade elliptic to narrowly ovate or broadly lanceolate, 5.5-9.0 x 2.5-3.8 mm, acute, above dark green and smooth, below light green with 30-70 rather conspicuous glandular dots evenly distributed over the surface. Uppermost leaves hardly changed in shape, forming a loose involucre. Flower on glabrous pedicels 2-4 mm long and c. 1 mm thick, in 2-4-fIowered, rather condensed corymbs. Bracts lanceolate to oblanceolate, 3.0-7.3 x 0.9-1.7 mm, acute, faintly ciliate, green, more or less glandular-punctate along the upper margins. Bracteoles attached to the middle or lower part of the pedicel, subulate, 2.0-4.4 x 0.7-1.2 mm, acute, faintly ciliate, pale green, eglandular. Calyx 6-9 mm, divided to c. 2/3, glabrous, rather inconspicuously glandular-punctate, brownish-green at the base; segments more or less cordate at the base (i.e., with overlapping 'ears'), broadly lanceolate in outline, 3.8-6.0 x 2.5-3.8 mm, moderately acute, red along the thin lower margins, often recurved, slightly thickened, and dark purplish at the apex. Petals pale pink on both sides, glabrous or slightly puberulent on the inside of the claw and lower part of the limb; claw 2-3.5 mm long, gradually widening into the limb: the latter broadly elliptic, 6.5-8.8 x 4.0-6.2 mm, obtuse to truncate, apiculate. Staminodes 2.5-3.4 mm long, erect, rather uniformly broad, glabrous at the base, patently pilose for most of their length, apically slightly expanded and tipped by a reddish gland c. 0.5 mm across. Stamens: filaments 1.2-1.7 mm long, erect or slightly incurved in the upper part, very gradually tapering from the glabrous base, patently pilose for most of their length, yellowish; anthers broadly ovoid, dorsifixed, versatile, 1.1-1.5 x 0.8-1.2 mm, brown, glabrous to pilose, tipped by a shortly stipitate, capitate gland c. 0.5 mm across. Ovary globose, c. 1.5 mm across, glabrous, brownish-green, upper part densely papillate (from pale, stipitate, glands); style c. 1 mm long, stout, recurved (but soon erect); stigma discoid to capitate, olive-brown. Mature capsule conspicuously shorter than the calyx which expands and becomes appressed to the fruit; upper part slightly papillate to bullate, brownish-green. Seeds narrowly ovoid to obliquely oblong, 3.9-4.5 x 1.7-2.0 mm.
