Description:

Description - Trees, often much branched, sometimes shrub-like, to 22 m tall; leafbearing branches 3-9 mm in diameter, the leaves aggregated at their ends. Leaf blades narrowly obovate to oblanceolate, 16-48 x 4-13 cm, glabrous, chartaceous, with 14-22 pairs of lateral veins; apices acuminate to long acuminate; bases acute to cuneate; margins entire to serrulate or infrequently serrate, the serration especially pronounced on upper one-half of blade. Petioles absent to 40 mm long, 2-6 mm thick, semi-circular in cross section. Inflorescences usually suprafoliar, infrequently axillary or cauline, racemose, puberulous to pubescent, with 1-8 flowers; rachis 4-60 mm, often with persistent bud scales at the base; pedicels 15-75 mm, subtended by a single ovate to lanceolate caducous bract 2-7 x 3-4 mm and bearing at various points along the length 2 ovate to broadly ovate or lanceolate bracteoles 2-8 x 2.5-7 mm. Flowers 9-20 cm in diameter; calyx usually an undulate rim 1-2.5 mm deep or less frequently of 4 shallow, broadly rounded or triangular lobes, the lobes 2-5 x 8-14 mm; petals (6-)8(-9), oblong, obovate, or oblanceolate, 25-95 x 15-50 mm, rusty-to-gray pubescent in bud, puberulous at anthesis, white inside and outside, with tinges of pink on the outside especially towards the apex; connate androecium base 819 mm high; outermost filaments 10-24 mm, white at base, often pink toward the apex; anthers 2-4 mm, yellow; ovary usually without costae, puberulous or pubescent, 4-7-locular, the summit white-pubescent to white-tomentose; style conical 1-3 mm long; stigma with 4-6 lobes. Fruits globose, truncate at apex, without costae, 30-70 x 30-80 mm, without persistent calyx lobes. Seeds rounded in cross section, black at maturity, 15-22 x 10-14 mm, with a distinctive yellow, contorted funcile, 14-35 x 4-12 mm. Seedlings with distinctive cataphyll, 4-5 mm long.

Discussion:

Ecology. Gustavia augusta is most commonly found along river margins but may also be encountered away from rivers, especially in habitats that have waterlogged soil for part of the year.

As with most widespread species, G. augusta exhibits considerable variability. Nevertheless, there are no clear discontinuities which permit the recognition of more than one species. The riverine habitat of G. augusta and possible dispersal by water favors distribution over a large area and lessens geographic isolation.
