Leaves sessile, erect or usually ascending, not tetrastichous, persistent; lamina (3-)5-30(-36) x 1-7 mm, upper triangular-lanceolate or narrowly elliptic to linear, lower triangular-ovate to ovate or elliptic, plane or margin recurved, not cucullate, midrib prominent beneath and smooth, concolorous or paler beneath, sometimes glaucous, subcoriaceous to chartaceous; apex acute to obtuse or (lower leaves) rounded, margin entire, base subcordate- amplexicaul to cuneate, not sheathing, free; basal veins 1-7, only midrib sometimes obscurely branched, tertiary venation very obscure or absent; laminar glands dense, not or scarcely prominent. Inflorescence l-c. 50-flowered, terminal, branching regularly dichasial/monochasial, rarely with paired flowering branches from 1-3 nodes below; pedicels 1-15 mm long (in fruit), bracts and bracteoles linear to subulate.
