Description
|
Unarmed trees, with lenticellate, glabrous branchlets. Leaves essentially glabrous, 6- to 12 (generally 6- to 8) -foliolate; petiole short; leaflets obliquely ovate or ovate-elliptic, 3-5 cm. long, short-acuminate apically, obtuse or rounded basally, coriaceous, markedly reticulate, with a prominent midvein and many con- spicuous lateral veins, usually alternate except terminally on leaf; petiolules flat- tened, rugose when dry. Inflorescence of many small flowers, as described for the genus. Flowers apetalous; calyx-lobes 4, narrowly ovate to elliptic or lanceolate, about 3 mm. long, subhirsute within, glabrous without, spreading; stamens usually 10, 7-8 mm. long; filaments slender, glabrous; anthers versatile, oblong, almost 2 mm. long; ovary suborbicular, flattened, hirsute marginally; style arcuate, up to 5 mm. long, bearing a capitate stigma. Legume orbicular or broadly ellipsoid, about 15 mm. broad, glabrous; seed almost enclosed by the aril.

Note
|
The species constitutes a source of the oleoresin "copaiba balsam", used medic- inally and in the manufacture of varnishes. It is readily confused with C. officinalis, but has narrow-elliptic leaflets in 3-6 pairs, whereas the latter has wide-ovate leaflets in 2-4 pairs.
