Dodonaea angustifolia

Description

Tree or shrub, dioecious (to monoecious), up to 20 m high, dbh up to 40 cm; Leaves ovate to elliptic (to elliptic-obovate), (including the petiole) 7.5-22 by 0.75-5 cm, index 3-9, thin pergamenta-ceous to chartaceous, coriaceous when alive; Inflorescences 4-7 cm long, with several about equally long ± erect branches, rather dense, with up to c. 50 flowers; Flowers polygamous, unisexual (or with some bisexual flowers on a male specimen). Sepals 4 (or 5), in male flowers ovate-elliptic, 2.75-3.5 by 2-2.25 mm, in female flowers elliptic, 2-3 by 1-1.5 mm, glabrous (to sparsely hairy outside) to fairly densely hairy inside, the margin partly to completely tomentose-ciliate; Stamens 5-9, scars inconspicuous in fruit; Fruits flattened, broad ellipsoid to orbicular, 5-13.5 by 7-12 mm, pergamentaceous to membranous, sparsely but conspicuously glandular, glabrous (or sparsely hairy, mainly along the upper part of the suture);

Distribution

Asia-Tropical: Jawa (Jawa present); Lesser Sunda Is. present; Maluku (Maluku present); New Guinea present; Philippines (Philippines present); Sulawesi (Sulawesi present), Tropics and subtropics present
Worldwide, in the Tropics and Subtropics; in Malesia known from Java, Lesser Sunda Islands, Philippines, Celebes, Moluccas, and New Guinea.

Uses

Planted as a garden fence and as a shade tree in plantations; it provides a good timber for building houses and is used as firewood. See .

Notes

1. For a long time, the present species was considered to be synonymous with D. viscosa and went under that name. This is notwithstanding the fact that, especially in Java, two different forms were known, the one coastal, the other one at higher altitudes, forms that were also different in several morphological characters. Junghuhn was one of the very few botanists who separated the two as species. The great attention paid since Linné f. to the leaf shape instead of to the flowers and the authority of Radlkofer, who ranked the two as forms only, seem to be mainly responsible for this situation.
2. The form from Java, the Lesser Sunda Islands in part, and Celebes is the most hairy one of the species; the other specimens from the Lesser Sunda Islands, the Philippines, and New Guinea are glabrous or have at most a few hairs on the inflorescences.
3. Throughout its area, D. angustifolia seems to be adapted to a drier and cooler climate than D. viscosa.
