Branchlets glabrous, puberulous, pubescent or pilose (usually in strips alternating with the leaf-bases). Leaves 0.5-1.3 cm long, alternate, erect-spreading or ascending, often subimbricate, ovate-lanceolate, lanceolate, linear-lanceolate, lanceolate-linear or linear, rarely slightly widened in the upper half, acute, subacute or obtuse, rounded or cuneate at the base, concave above, ± keeled or rounded beneath, often swollen behind the apex, glabrous or ± pilose-ciliate, rarely pilose beneath. Flowers in terminal clusters. Peduncles 2-8 mm long, glabrous, sometimes purplish, with bracteoles on the lower half. Sepals 1.5-3 mm long, ovate-or oblong-lanceolate, ovate-oblong or ovate, obtuse, acute or acuminate, obtusely keeled, usually with conspicuous glands beneath, glabrous or ciliate, sometimes pubescent above, often hyaline at the margin. Petals 3.5-5.5 mm long; blade oblanceolate, obovate or obovate-elliptic, very obtuse, often retuse, rarely pilose above and on the margin, with a conspicuous gland behind the apex; claw half to nearly twice as long, narrowly linear, glabrous, or ciliate on the lower half. Stamens glabrous. Staminodes resembling the petals but usually slightly shorter, villous on the lower half.
