Morphology Leaves
Leaves distichous, bright green, narrowly ovate or narrowly elliptic, 2–8.5(–10) × (0.5–)2–2.5(–3.8) cm, acute at the apex, obtuse to rounded at base, sharply toothed, ± glabrous or lower leaves sometimes pubescent; petiole 2.5–6 m long; stipules almost leafy, linear to lanceolate or falcate, up to 10 mm long, 1.5 mm wide, sometimes with those of a pair unequal, one linear and the other lanceolate (but not always in African material)
Morphology Reproductive morphology Flowers
Flowers solitary and axillary or less often few together in the axils; pedicel 2–12 mm long, puberulous; calyx 5–8 mm long, glabrous or ciliate, divided to middle into triangular acuminate lobes
Morphology Reproductive morphology Flowers Corolla
Corolla creamy white, yellow, pale orange or apricot, sometimes darker orange at base; petals (4–)6–9 mm long.
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal column 1–2 mm long, pubescent and sometimes glandular
Morphology Reproductive morphology Fruits
Mericarps (5–)6–8, 3–4 mm long, sparsely pubescent or ± glabrous, reticulate on back, striate on sides, breaking between the ridges in both areas; lateral edges sharp and muricate; awns rather stout, 1–1.5 mm long, diverging
Figures

Ecology
Grassland, bushland, forest edges, seasonally swampy areas on black cotton soil, riverine and lacustrine, stony sandy soil; weed of cultivation; 0–1650 m
Note
Borssum Waalkes treated S. carpinifolia L. f. as a subsp. of S. acuta and Rodrigo as a variety but it is a perfectly distinct species, formerly widespread in the Mascarene Is. Marais does not state that it occurs anywhere else but it is widely recorded in the tropics in the literature.
