Leaves rarely flat or concave, linear to very narrowly obovate, 2-6 mm wide, with prominent marginal veins and longitudinal veins 3 below, 1 above (sometimes upper vein obscure). Inflorescence a solitary axillary umbelliform raceme, with 8-14 flowers; pedicels cream-white, glabrous. Perianth cream-white. Pistil 5-9.5 mm long; gland subglobular, ±compressed, 0.2 mm high. Fruit 1-3 per axil, scarcely woody, sessile, obliquely ovate-acuminate (almost straight abaxially), usually slightly recurved, 0.6-0.8 cm long, 0.3-0.35 cm wide, scarcely beaked but with prominent readily broken apiculum.
