Leavessessile, erect and subimbricate to narrowly spreading or slightly outcurving, deciduous above the base before fading; lamina 4-15 x 0.7-3 mm, ± narrowly oblanceolate to narrowly oblong, ± incurved-cucullate, midrib distally prominent otherwise impressed or plane beneath, concolorous or with margin rather narrowly hyaline, lustrous pale green, not glaucous, subcoriaceous; apex acute, base angustate, broadening below, not or scarcely sheathing, pairs united to form narrow interfoliar ridge; basal vein 1, unbranched or with 1-2 pairs of obscure lateral branches; laminar glands dense, visible above only, or obscure. Inflorescence 1 -flowered, with pseudo-dichotomous branches from node below; pedicel 2.5-7 mm long; upper leaves not transitional. Flowers 6-20 mm in diam., stellate.
