Spines borne at right-angles to the parent stem 5–20(–30) mm above the axil, 3–13 cm long, 2–3.5 mm diameter, sometimes bearing branch-spines, very stout, terete, yellowish-green, the spine-tip often orange-brown; spinules absent.. Scale-leaves 2 mm long, 1 mm wide, triangular, acute, scarious, sometimes persistent.. Leaves infrequent, subsessile or with a petiole up to 1–2.5 mm long; stipules 1 mm long, very early caducous; leaflets elliptic, obovate or obovate-spathulate, sessile, 2.2–6.2 cm long, 1.2–3.8 cm wide, apex rounded, obtuse or acute, sometimes minutely apiculate, base cuneate, thinly coriaceous, glabrous above, often very sparsely adpressed puberulous below; foliole 1–2 mm long, linear, rarely foliar and to 1.7 cm long, 0.4 cm wide.. Inflorescence generally on the spines, but sometimes on the parent axis, fasciculate; pedicels 3.5–10 mm long, densely white-tomentellous.. Flowers 4 (rarely 5)-merous, arising from a small swollen tomentellous cushion, sometimes scented; sepals ovate, 4.5–5 mm long, 2–2.5 mm wide, acute, caducous, shortly puberulous outside; petals yellowish green, cream or white, rarely orange, narrowly obovate-oblong, 6–7 mm long, 2–2.5 mm wide, acute, gradually narrowing to the base, glabrous within; stamens 8; anthers 2 mm long, 1 mm wide; ovary 1 mm high, densely silky hairy initially in bud, usually very early-glabrescent; style 1–1.5 mm long.. Fruit not markedly elongating in early development, at first ellipsoidal and pointed at both ends, eventually ovoid, ripening yellow to orange or pale red, to 3.5 cm long, to 2 cm diameter, smooth; seed in a hard endocarp enclosed in a thin outer layer.
