Morphology General Habit
Shrub 0·4–1·5(3) m. high, with slender spines up to 1 cm. long, mostly axillary but sometimes terminating short branches, glabrous or ± puberulous, without latex; branches somewhat flattened, slightly angular, pale vinous red and glabrous or puberulous when young, becoming terete, greyish-brown, not striate, glabrous, without visible lenticels.
Morphology Leaves
Leaves often fasciculate, petiolate; lamina pale green, concolorous, 1·6–7 × 0·9–1·7 cm., oblanceolate to narrowly elliptic or linear, subacute to rounded and mucronate at the apex, with margin shallowly glandular-denticulate to subentire, angustate at the base, chartaceous, glabrous or puberulous (especially below), with lateral nerves and lax reticulate venation not prominent or only slightly so below; petiole 1–3(7) mm. long.
Morphology Reproductive morphology Inflorescences
Cymes monochasial or subdichasial, solitary and axillary or 2–6 in fascicles on short shoots, with peduncle 5–16(24) mm. long, glabrous or puberulous; pedicels 2–9 mm. long, articulated c. 1·5 mm. below the flower; flowers 3–7(10) in each cyme, dioecious.
sex Male
Male flowers 5–7 mm. in diam.; sepals 1–1·2 mm. long, triangular-ovate, subacute to rounded, with margin ciliolate to entire, glabrous or puberulous; petals 5, pale yellow, 2–2·5 mm. long, narrowly oblong, with apex irregularly ciliolate, glabrous; stamens 5, with filaments c. 2 mm. long, arising below the disk; disk flat, entire or shallowly 5-lobed; pistillode shorter than stamens, ovoid-cylindric, c. 1/4-immersed in the disk, with stigma 3-fid, sessile.
Morphology Reproductive morphology Flowers
Female flowers 3–4 mm. in diam.; sepals 0·5–0·7 mm. long; petals 1·5–2 mm. long; staminodes with filaments c. 0·8 mm. long; disk narrower than in male flower; ovary (2)3-locular, exceeding the stamens, subglobose, with style as long as each of 3 stigmatic lobes; otherwise as in male flower. Male flowers 5–7 mm. in diam.; sepals 1–1·2 mm. long, triangular-ovate, subacute to rounded, with margin ciliolate to entire, glabrous or puberulous; petals 5, pale yellow, 2–2·5 mm. long, narrowly oblong, with apex irregularly ciliolate, glabrous; stamens 5, with filaments c. 2 mm. long, arising below the disk; disk flat, entire or shallowly 5-lobed; pistillode shorter than stamens, ovoid-cylindric, c. 1/4-immersed in the disk, with stigma 3-fid, sessile.
sex Female
Female flowers 3–4 mm. in diam.; sepals 0·5–0·7 mm. long; petals 1·5–2 mm. long; staminodes with filaments c. 0·8 mm. long; disk narrower than in male flower; ovary (2)3-locular, exceeding the stamens, subglobose, with style as long as each of 3 stigmatic lobes; otherwise as in male flower.
Morphology Reproductive morphology Fruits
Capsule yellow, sometimes red-tinged, 7–13 mm. long, obconic, 3-gonous (or flattened if 2-locular), truncate, chartaceous, smooth.
Morphology Reproductive morphology Seeds
Seeds 2–3, purplish- or reddish-brown, rugose, with a yellow aril at the base.
