Range:
Pantropical
Habitat:
usually on edges of montane forest up to c. 1600 m. but also at lower altitudes.
Description:
Small tree up to 10 m. tall or shrub; branchlets angular, glabrous, resinous. Leaves simple, spirally arranged; petiole up to 6 mm. long, glabrous; lamina up to 10 × 3 cm., narrowly elliptic, glabrous, resinous, apex acute and usually acuminate, margin entire, base narrowly cuneate and decurrent into the petiole; lateral nerves numerous (usually up to c. 20 pairs). Inflorescence usually c. 2 cm. long, terminal or subterminal, somewhat corymbose; peduncle short (rarely more than 5 mm. long). Flowers greenish-yellow (often bisexual fide Radlkofer); pedicels up to 5 mm. long (accrescent to 12 mm. long in fruit), filiform, glabrous. Stamens usually 6; anthers 3 mm. long. Ovary (2)3(4)-locular; style 4–6 mm. long, (2)3(4)-lobed. Fruit up to 2 × 2 cm., 2–3(4)-locular, subcircular in outline, emarginate at apex and base, with 2–3 glabrous membranous wings c. 4–6 mm. broad, very shortly stipitate. Seed black, 3 × 2 mm., lenticular, glabrous.
Notes:
Ptelea viscosa L. and Dodonaea viscosa Jacq. are nomenclaturally independent as they are based on different types. Jacquin was perhaps unaware that Linnaeus had placed the species (already well known) in Ptelea.A somewhat complicated system of dividing this widespread species into infra-specific taxa (varieties, forms and subforms) was elaborated by Radlkofer (op. cit.: 1368 et seq.) The only specimen in that work cited from our area appears under “specimina quoad formam indeterminata”. Brenan (loc. cit. 1953) says that the Brass specimens from Nyasaland are referable to var. vulgaris forma burmanniana (DC.) Radlk. as defined by Radlkofer.
