Characteristics

Shrub with pendent branches, or generally scan-dent, 2-20 m; stem 1-15 cm ø; bark rather smooth, grey; old branches with strong obtuse ramal straight or slightly curved thorns. Branchlets often horizontally spreading, patently puberulous or pubescent at younger parts, glabrescent below, striate-wrinkled longitudinally in dry specimens (not transversely ridged!). Leaves almost distichous, ovate-elliptic-oblong, apex broadly attenuate to rounded, base slightly inequilateral, attenuate to obtuse, not rarely rounded and plicate, thin-coriaceous, dark to yellowish green, somewhat shining and glabrous above, initially short-pubescent at midrib beneath, glabrescent, 2-8 (-9.5) by (0.3-) 0.8-3.5 cm; nerves 5-8 pairs, unequal-spreading, rather inconspicuous on both faces as are the reticulations; petiole short-pubescent, 5-7 (-10) mm. Racemes 1-3 per axil, simple or branched, obliquely ascending, many-flowered, densely short-hairy, bracteate at base, 0.5-3.5 cm; bracteoles distichous, obtuse, keeled, pubescent, c. 2 mm, caducous; pedicels thickened at the very base, glabrous, 1-1.5 mm. Calyx cup-shaped, truncate, ci-liolate, 0.5-1 mm high, c. 1.5 mm ø, much accrescent in fruit. Petals 3, of which 2 (rarely all) are split about halfway, thus 5(-6) petals seemingly present, linear-oblong, apex acute and incurved, glabrous, white, scented, 7-9 by c. 1.5 mm. Stamens 3, in the long-styled form reaching to the base of the sinus of the petals, in the short-styled form reaching 2-2.5 mm beyond it; filaments free for a short part; anthers oblong, c. 1.5 mm. Staminodes with very narrow void, deeply bifid cells. Ovary ovoid, glabrous; style either long (5-6 mm) or short (1.5-2.5 mm); stigma obscurely 3-lobed. Drupe broadly ovoid to subglo-bose, covered for the lower ⅔ or more by the accrescent firmly membranous calyx, apiculate, orange to yellow (0.8-) 1.5 by (0.6-) 1 cm.
