Inflorescence: axillary dichasial cymes or flow­ers borne in clusters. Flowers bisexual or uni­sexual, hypogynous, Pedicel 2-5 mm long, pedicel and calyx often with a few short hairs. Disc 4-lobed, not adnate to perianth. Stamens 8. Fruit subglobose, ± 15 x 14 x 14 mm, glabrous; putamen smooth; pseudo-aril red, with 4 arms, 2 commissural arms reaching al­most to apex of putamen, 2 facial arms shorter.

Information Tree up to 9 m. tall; bark smooth, green, peeling; branches cinereous-pubescent when young, often spiny. Leaves 3-foliolate; petiole up to 4·5 cm. long, sparsely pilose; leaflets up to 6 × 3·5 cm., terminal usually very broadly obovate, the laterals smaller and broadly elliptic to rotund, apex shortly apiculate or rounded, margins finely crenate-serrate but entire towards the base, base cuneate, glabrous or with a few scattered hairs. Flowers appearing with the leaves or before the leaves, in clusters in short side-shoots or (male) in short dichasial cymes; pedicels c. 2 mm. long, glabrous.

Leaves narrowly oblanceolate to obovate or lanceolate in outline, often turning red when old, 2–11 cm long, including 2–16 mm long petiole, subglabrous or, more often, pubescent with ± appressed to spreading hairs up to 0.6 mm long; rhachis sometimes slightly winged; leaflets (3–)5–45(–51), entire, subsessile, ovate to oblong-elliptic or obovate, rounded to cuneate at the base, obtuse or broadly pointed at the apex, up to 13(–18) x 8(–10) mm. Flowers in few-flowered pubescent racemes or panicles up to 6(–10) cm long; bracts oblong to triangular, up to 6 x 2.5 mm; pedicels 1–8 mm long. Calyx c. 1.5 mm long, glabrous or pubescent; petals ovate, c. 2–3 mm long, glabrous or medially pubescent outside; filaments 0.8–1 mm long, ovate, abruptly narrowed near the middle into a filiform tip, papillose. Fruit 3(–4)-celled, pear-shaped to subglobose, sometimes ± winged, glabrous, 8–22(–25) x 7–11(–14) mm; stones ± cross-like, with apical and basal horns as well as lateral horns, without or with a narrow ± caducous wing.

Information Annual herb, sometimes woody at the base, 0.05–1.5 m; stems reddish or green, stellate-scabrid to glabrous, succulent, often woody at base. Leaves shortly elliptic or rhombic-orbicular, sometimes wider than long, shallowly 3-lobed to 1/5 way to the base, lateral lobes sometimes slightly diverging, (2.7–)3.5–8.6 cm long, (1.6–)1.8–6.7 cm wide, base rounded to cuneate, tip shortly acuminate, margin 1(–2)-serrate(-dentate), membranous, softly hairy to subscabrid to glabrous above, stellate-softly hairy to subscabrid beneath; glands crater-like, elliptic, ± 0.75 mm long, replacing the lower 1–2 pairs of teeth on lower surface; petiole (5–)8–38 mm long, hairy; stipules narrowly triangular, 1–4 mm long, ± 1 mm wide, dark brown, hairy. Inflorescence terminal, many-branched, up to 45 cm long; basal nodes with slightly reduced leaves, becoming more linear and further reduced towards the top, internodes 1.5–4 cm long, nodes with 1–5 leaf subopposed cymes, each 1(–3)-flowered; peduncles 1–3 mm long, sometimes in lowest nodes several inserted on a short stem 1–5 mm long; bracts as stipules, 1.5–2 mm long; pedicels ± 1 mm long. Sepals elliptic-linear, 2.5–4 mm long, sparsely stellate-hairy outside, apical spine 0.5 mm long, pink in bud. Petals spathulate, the blade oblong, 3–3.5 mm long, 0.5–1 mm wide, the basal 0.5 mm of the claw sparingly hairy at the margin. Stamens 5(–6); ovary sparsely hairy. Fruits 3–6 per node, indehiscent, ovoid, 5–7.5 mm long, 4–5 mm wide, fruit body ± 4 mm long, 3 mm wide, covered in densely long brownish-white hairs, with ± 65–90 forward pointing dark brown spines, each glabrous apart from a line of glistening white hairs along their forward length and each with a translucent, forward directed recurved hair at the tip.
