Description
Species Description - Young branches villose with white to brown hairs or glabrous, becoming smooth, usually dark brown, finally cracked or fissured, lenticellate. Spines usually present, 1-2 cm long, axillary or terminating lateral branches. Leaves spirally arranged and spaced on young growth, soon becoming fascicled on short shoots, 1.3-10.7 × 0.7-4 cm, oblanceolate, apex rounded or obtuse, rarely acute, base long narrowly attenuate, chartaceous, sometimes becoming coriaceous, loosely villous with white or brown hairs when young, soon becoming glabrous on the upper surface except for residual hairs along the midrib, lower surface remaining villose or becoming glabrous; venation eucamptodromous to brochidodromous, marginal vein absent, midrib flat or slightly sunken on the upper surface; secondary veins 5- 9(-12) pairs, ascending, usually arcuate and slightly convergent; intersecondaries usually short to moderate, occasionally long; tertiaries reticulate or reticulate-areolate, conspicuous on the upper surface. Petiole 0.2-1.1 cm long, slightly channelled, villous to glabrous. Flowers bisexual, the fascicles axillary and clustered on the short shoots. Pedicel 2-9 mm long, villous to glabrous. Sepals (four)five, 1.75-3 mm long, ovate to suborbicular, obtuse to rounded, villous, pubescent or rarely glabrous outside, glabrous inside. Corolla 3-4(-5) mm long, tube 0.75-1.5 mm long, glabrous; lobes five(six); median segment ovate, oblong or elliptic, apex rounded, often erose, often auriculate at base; lateral segments lanceolate or falcate, 0.75-1.75 mm long. Stamens five(six), glabrous; filaments 1.25-2 mm long, anthers 0.75-1.25 mm long, lanceolate. Staminodes five(six), 1.25-2(-3) mm long, lanceolate, often infolded, often erose, glabrous. Ovary globose or ovoid, 5-8-locular, strigose; style 0.75-1.5 mm long after anthesis, glabrous; style-head simple. Fruit 0.7-1.4 cm long, broadly ellipsoid to oblanceolate, apex rounded, base rounded or slightly tapered, smooth, glabrous; pericarp 0.5-2 mm thick, fleshy. Seed one(two), 0.6-1.1 cm long, ellipsoid, often with a truncate base; testa hard, smooth, shining, 0.25-2 mm thick; scar basal, nearly always in two parts, a circular or planoconvex basal part 1-2 mm across and a smaller laterally elongate part on the abaxial surface, the two sometimes coalescing; embryo vertical, with plano-convex cotyledons and slightly exserted radicle, surrounded by a thin layer of endosperm.
