Morphology General Habit
Tree to 9 m high, with a short stout trunk and dense rounded crown of ascending branches; terminal branchlets sharply (3–)4(–5)-angled, regularly constricted into segments 5–15 cm long, 4–6 cm wide; angles straight to shallowly sinuately toothed, with teeth 1 cm apart
Morphology General Spines
Spine-shields very obtusely triangular, to 10 x 7 mm including the flowering eye above; spine-pairs stout, to 5 mm long, often vestigial or apparently absent; prickles obsolete or vestigial on young growth; spines and spine-shields quickly becoming corky, to form a broad ridge along the angles
Morphology Leaves
Leaves oblanceolate on seedlings and young growth, to 25 x 8 mm, deltoid on older growth, c. 5 x 5 mm, quickly deciduous
Morphology Reproductive morphology Inflorescences
Cymes 1–5 crowded together, 1-forked, on stout peduncles 5 mm long; bracts rounded, c. 4 x 6 mm
Morphology Reproductive morphology Inflorescences Bracts Involucre
Cyathia 12 mm in diam.; glands 4.5 mm broad, golden yellow
Morphology Reproductive morphology Flowers Perianth
Perianth of the female flower obvious, irregularly divided into 3 deeply filiform-toothed lobes to 1 cm long; styles 4 mm long, with thickened shortly bifid apices
Morphology Reproductive morphology Fruits
Capsule shortly exserted on a stout pedicel 5 mm long, subglobose to very obtusely 3-lobed, c. 15 x 20 mm, fleshy, with thick walls, white becoming bright red, then hardening before dehiscence to become deeply 3-lobed
Morphology Reproductive morphology Seeds
Seeds subglobose, slightly compressed, 4.5 x 3.7 mm, smooth, grey.

Morphology General Habit
Tree to 30 m. high, with a simple trunk to ± 90 cm. in diameter and roughened grey bark; primary branches ascending, rebranching irregularly and ± densely at the apices to form a spreading rounded crown; terminal branchlets fleshy, 3(–4)-angled, 5–17 cm. wide, deeply and thinly winged with wings 2–7 cm. wide, ± constricted at irregular intervals into oblong segments 15–40 cm. long; angles straight to sinuately toothed, with teeth 1.5–3 cm. apart.
Morphology General Spines
Spine-shields rounded, to 5 mm. in diameter, eventually extended to 5 mm. above the spines to enclose the flowering eye; spines stout, 1–3 mm. long; prickles absent or vestigial; spine-shields and spines becoming corky and eventually disintegrating.
Morphology Leaves
Leaves persistent for some time on young growth, obovate, to 15 × 6 cm., fleshy, midrib keeled on the lower surface, base tapering to a petiole ± 1 cm. long.
Morphology Reproductive morphology Inflorescences
Cymes 1–3 in a horizontal line or occasionally 4 crowded together, 1-forked, with stout peduncles, and cyme-branches 3–4 mm. long arranged in a vertical plane; bracts rounded, ± 4 × 7 mm.
Morphology Reproductive morphology Inflorescences Cyathia
Cyathia ± 4 × 7 mm., with cup-shaped involucres; glands transversely elliptic, ± 2 × 4 mm., with undulate margin, not quite touching, yellow; lobes transversely elliptic, ± 2 × 3.5 mm.
Morphology Reproductive morphology Flowers
Male flowers:bracteoles spathulate, plumose; stamens 6 mm. long. Female flower:perianth irregularly divided into 5–12 lanceolate lobes with toothed margins, to 6 mm. long; styles 3.5 mm. long, joined at the base, apices thickened, ± bifid.
sex Male
Male flowers:bracteoles spathulate, plumose; stamens 6 mm. long.
sex Female

Morphology Reproductive morphology Fruits
Capsule on a stout pedicel 3 mm. long, subglobose, to 12 × 16 mm., fleshy, red, hardening before dehiscence to become obtusely 3-lobed with woody walls 2–3 mm. thick.
Morphology Reproductive morphology Seeds
Seeds subglobose, slightly compressed laterally, 4.5 mm. in diameter, yellowish brown speckled with black, smooth.
