Description:
Description - Small trees to 4 m tall, with few branches; leaf-bearing branches 5-7 mm in diameter, the leaves tightly grouped in 2-3 clusters at their ends. Bark gray, rough, somewhat fissured longitudinally. Leaf blades narrowly oblong to narrowly oblanceolate, attenuate to an acute base, 26-41 x 7-9.5 cm, velutinous throughout abaxially, with 25-32 pairs of lateral veins; apices acuminate; margins serrulate to serrate. Petioles absent to 30 mm long, 3-6 mm thick, semi-circular in cross section. Inflorescences suprafoliar, racemose, buff-rusty tomentose, with 4-10 flowers, the rachis 20-60 mm; pedicels 35-100 mm, subtended by a single caducous bract and bearing at or above the middle 2 ovate to lanceolate, cucullate bracteoles 2.5-6 x 2-4 mm. Flowers 10-14.5 cm in diameter; calyx with 4 rounded to triangular lobes, 3-5 x 9-12 mm; petals 8 narrowly elliptic to oblong, 50-65 x 20-25 mm wide, densely gray-pubescent in bud, puberulous at maturity, white, sometimes rose-red outside; connate androecium base 10-15 mm high; outermost filaments 18 mm, rose-red; anthers 3-4 mm, yellow; ovary obscurely 4-costate, buff-rusty-tomentose, 4-locular, the summit entirely white-tomentose to merely puberulous in lines; style 1-2 mm; stigma with 4 lobes. Fruits globose, truncate at summit, obscurely 4-costate, 25 x 28 mm, possibly larger, with 4 broadly triangular lobes 3 x 11 mm. Seeds without expanded fleshy funicles. x = 17.

Discussion:
Ecology. Gustavia angustifolia is a tree of the dry seasonally deciduous forests of the coastal plain of Ecuador and Colombia. Although it is common in the vicinity of Guayaquil it is poorly collected and little is known of its ecology. Valverde (collection no. 511) reports that it blooms in October and fruits in November. All flowering collections from the vicinity of Guayaquil have been gathered between July and October.This species is easily recognized by its pubescent abaxial leaf surface as most species of Gustavia have glabrous leaves.Ruiz and Pavon were the first to recognize this species, providing it with two illegitimate names. The first, G. corymbosa, appears on their collection label and the second, G. angusta, is an unpublished manuscript name not to be confused with G. augusta of Linnaeus. Berg (1856) published G. ruiziana based on the Ruiz and Pavon material. However, this name is synonymous with G. angustifolia which was published in 1844 by Bentham.
