Morphology General Habit
Shrub or small tree to 3 m. high, sometimes semi-scandent, with spines up to ± 1 cm. long, without latex; branches ± flattened, ± angular, reddish purple and glabrous when young, becoming terete, striate, without lenticels.
Morphology Leaves
Leaves not fasciculate, petiolate; lamina mid-green, paler beneath, obovate-elliptic or elliptic to oblong, 5.5–10.7 × 2.6–5 cm., obtuse to subacuminate at the apex, with margins crenate-serrate with teeth rounded and incurved, cuneate at the base, coriaceous, glabrous, with lateral nerves and densely reticulate venation slightly more prominent beneath; petiole 6–10 mm. long.
Morphology Reproductive morphology Inflorescences
Cymes 3–6 cm. long, slender, subdichasial to monochasial, solitary or paired, axillary or usually in axillary panicles, with peduncle 29–40 mm. long, glabrous; pedicels 3–4 mm. long, glabrous, articulated at the base; flowers ± 10–16 in each inflorescence (± 5 in each cyme), 4–5 mm. in diameter, bisexual.
Morphology Reproductive morphology Flowers Calyx
Sepals 5, subequal, broadly ovate or triangular-ovate to oblong, ± 1 mm. long, obtuse to rounded, glabrous, with margin ciliolate.
Morphology Reproductive morphology Flowers Corolla
Petals 5, white, obovate-spathulate, 2.5–3.5 mm. long, with margin ciliolate.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 5, ± three-quarters as long as the petals, with filaments 1–2 mm. long, slender, arising below the disc.
Morphology Reproductive morphology Flowers Disc
Disc narrow, convex, scarcely 5-lobed.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary 3-locular, globose, slightly immersed in the disc; style shorter than ovary, 3-branched, with small stigmas.
Morphology Reproductive morphology Fruits
Capsule green to reddish, obconic–3-gonous, 12 mm. long, retuse, coriaceous, glabrous.
Morphology Reproductive morphology Seeds
