DIAGNOSTIC DESCRIPTION
Shrublet 0.05-0.25(0.4) m long, much branched, wiry to lignified, with branches slender, ascending to prostrate, diffuse; wholly glabrous; red or black glands present in leaves, flowers and sometimes stems. Stems 4-lined and ancipitous at first, eventually terete; cortex becoming bright red, sometimes with a few black glands; bark striate, reddish brown. Leaves paired, free, petiolate, with petiole c. 0.5-1 mm long; lamina (2.5-)4-14(-22) x (l-)2.5-7.5(-9) mm, oblong or elliptic (or rarely ovate) to obovate or oblanceolate, concolorous, glaucous beneath or on both sides, (sub?)coriaceous; apex rounded, margin plane to subrecurved, base cuneate to long- angustate or pseudopetiolate; venation: 0-2(-6) pairs of laterals, with tertiary reticulation visible in larger leaves; laminar glands sparse or absent, occasionally black; submarginal glands scattered, black; intramarginal glands dense. Inflorescence l(2-3)-flowered, terminal and often also 1-flowered axillary or terminating branches from up to c. 6 axils below, sometimes with up to 4 flowering branches from scattered lower nodes, the whole appearing racemiform; bracteoles narrowly oblong or absent; pedicels 5-9 mm long, slender, 'erect or resupinate'. Flowers 10-13(-15) mm in diam.; buds cylindric-ellipsoid, rounded, bright sealing-wax red (at least in prostrate form). Sepals green or pinkish red, (2-)3-5(-6) x 0.7-2.5 mm, free or almost so, not or slightly imbricate, equal, lanceolate or narrowly oblong or narrowly elliptic to linear, acute to rounded, chartaceous to submembranous, margin entire or irregularly glandular-denticulate; veins (3)5-7, not or only midrib prominent, often branched; laminar glands pale, punctiform or elongate, dense to sparse, often also 1-5 black, scattered; inframarginal glands pale, dense to sparse; marginal black glandular teeth 0-c. 10, elongate. Petals bright yellow, tinged bright red outside in bud, 6-12 x 2.5-4.5 mm, 2-2.5 x sepals, elliptic to oblong, obtuse with apiculus acute, lateral, with laminar glands scattered, punctiform or rarely striiform or linear, pale or sometimes some towards apex black or reddish. Stamens 20-30, longest 6-8 mm, 0.75-0.8 x petals; anther gland black. Ovary 2 x 1.5 mm, ovoid-ellipsoid to ellipsoid, acute to acuminate; styles 3-4 mm long, c. 2.5 x ovary, divergent. Capsule 4-5 x 3-4 mm, ovoid, subcoriaceous, surrounded by old petals, with valves longitudinally vittate, shorter than sepals. Seeds reddish brown, c. 1 mm long, ecarinate; testa linear-foveolate.
