Bramley, G.L.C., Forest, F. & De Kok, R.P.J. (2009) Taxon 58(2): 508.
Trunks of large trees fluted and twisted. Yellow or orange layers may be visible in the blaze. Blaze darkens to greenish brown on exposure.
Leaflet blades about 6-13 x 3-4 cm. Numerous, small, yellow glands normally visible with a lens on the underside of the leaflets. Stalk of the middle leaflet longer than those of the lateral leaflets.
Inflorescence about 15-25 cm long, pedicels densely glandular, about 1.5-3 mm long. Calyx almost truncate or with four short lobes at the 2-lipped apex, glabrous, glandular outside, tube cylindrical, about 1.5-3 x 1.5-2 mm, lobes rounded to shortly acute, up to 0.5 mm long. Corolla 4-lobed at the apex and tubular below, pubescent and glandular outside, glandular-puberulous on the inner surface of the lobes, villous inside the tube and the throat. Tube +/- cylindrical, about twice the length of the calyx, about 4-5 x 2-2.5 mm, lobes about 2-4.5 x 2-5 mm. Stamens included or slightly exserted, attached to the lower half of the corolla tube. Staminal filaments filiform, glabrous in the upper part, villous in the lower half, about 3-4.5 mm long, anther locules +/- free and divaricate towards the base. Ovary globular, glabrous, glandular at the top, 1-1.2 mm diam. Style almost included, glabrous, filiform, about 3-4 mm long, stigma minutely bifid.
Fruits globular or ellipsoid, glabrous about 6-10 x 4-8 mm, calyx accrescent, persistent at the base. Seed enclosed in a stone about 6 x 4 mm, seeds about 3.5 x 1 mm. Embryo about 3-3.5 mm long, cotyledons much wider than the radicle.
Cotyledons broadly ovate, 7-8 x 5-6 mm. First pair of leaves toothed. At the tenth leaf stage: leaflets elliptic, apex acute, base cuneate, upper surface clothed in short, pale hairs, undersurface with numerous small yellow glands, margin toothed for almost the entire length of the leaflet blade; petiole, stem and terminal bud clothed in short, pale hairs. Seed germination time 41 to 117 days.
