Information
Shrub or small tree, (2)3–7(10) m. high, much branched; stems smooth, angular when young, later terete. Leaves evergreen; petiole 1–2 cm. long; lamina 3·5–35 x 2–7·6 cm., very variable in shape, those on young shoots narrowly oblong to oblong-linear with margin spinose-dentate, those on mature shoots narrowly to broadly obovate with margin crenate to entire, all rounded to retuse at the apex, cuneate to rounded at the base, coriaceous; stipules subulate. Inflorescence (l)3–12(17)-flowered, pedunculate, in leaf axils; peduncle 1–9 cm. long, usually ± flattened, 1·5–5 mm. wide, sometimes bearing at the apex 1–2 leaf-like bracteoles c. 1 x 1 cm.; bracteoles otherwise small, scale-like, deciduous; pedicels 0·6–1·8 mm. long. Sepals c. 2·5 x 3·5–4 mm., united in the lower 1/2, with lobes triangular-oblate, apex rounded, margin entire. Petals greenish- or yellowish-white, 1·2–1·7 x 0·9–1·2 cm., broadly oblong-ovoid, obtuse, ± fleshy. Stamens with filaments c. 1·2 mm. thick; anthers c. 5 x 2·5 mm. Disk-lobes with filaments 4–6, linear, unequal. Ovary 5-angled, c. 8–10 mm. long including style. Drupe 4–10 x 1·9–3 cm., ovoid to oblong-fusiform or cylindric, prominently 5-ribbed (in our area), with mesocarp woody at first but said to become eventually pulpy and edible. Seeds 4·5–7·5 x 3–3·5 mm., brown or blackish, irregularly compressed-ellipsoid, carinate, minutely rugulose in ridges.

Notes
The variation in Brexia madagascariensis is greatest in Madagascar. No specimens with the long narrow spinous leaves have been seen from Africa or Zanzibar. Plants from these areas have relatively broad obovate entire or subentire leaves which, however, can be matched with Madagascar material. If the lack of spinous leaves proves to be constant on mainland plants, then some infraspecific taxonomic recognition of these populations might be desirable. Likewise, the small-fruited plants from the Seychelles may prove to belong to a distinct species.
