Description:
FZ: “Tree up to 15 m. high; crown flat or umbrella shaped; young branchlets densely and rather shortly pubescent. Leaves: gland on upper side of petiole squat and sessile, or somewhat raised, 0.25-0.75 mm. high; pinnae (3)6-12 pairs; leaflets (12)16-33 pairs, (5.5)6.5 × 1.25-4.5 mm., slightly falcate to oblong, with apex usually slightly asymmetric, obtuse to subacute, ± appressed-pubescent on both surfaces or glabrescent above; lateral nerves ± raised and visible beneath; lower surface of leaflet paler. Flowers white, on pedicels 1.5-2 mm. long; bracteoles soon caducous, fallen by the time the flowers open. Calyx 1.5-2.25 mm. long, densely shortly pubescent outside. Corolla 4-5 mm. long, densely short-pubescent or puberulous outside. Staminal tube not or scarcely exserted beyond the corolla; filaments c. 1 cm. long or less. Pod apparently indehiscent, 10-27 × cm., oblong, puberulous over the surface. Seeds c. 12 × 7 mm, flattened.” The key in FZ splits the species with smaller leaflets, generally less than 3 mm. wide, from those with leaflets 4-4.5 mm. wide. This distinguishes A. isenbergiana from A. zimmermannii, although the latter is marginally on the larger size, and A. schimperiana, is borderline, appearing on both forks of the key. The oddly disjunct distribution of A. isenbergiana suggests that specimens assigned to this species may be hybrids of A amara and A. zimmermannii. In its distribution, it is roughly sympatric with A. zimmermannii, the less common of the putative parents.
