Shrubs
0.9–2.5 m

2.2–4.5 cm
, glabrous, chartaceous, concolorous; glands conspicuous; base cuneate or rounded; apex acute, acuminate or cuneate; midvein adaxially impressed; lateral veins visible, not arched, 6 to 12 pairs; intra-marginal vein
1–3 mm
or less from the margin, margin flat. Inflorescence axillary, a fascicle, sometimes visible only two flowers per axis, the axis frequently inconspicuous, when visible ca.
1 mm
long; bracts lanceolate, 0.6 ×
4 mm
, pubescent, persistent in the fruit; pedicels
18–26 mm
