Flowering and Fruiting
The fruit is an oblong-ovoid pointed nut, 3.8 to 5.5 cm (1.5 to 2.2 in) long, that matures in September and October of the year of pollination. Nuts occur singly or in clusters of from 2 to 5. The kernel or seed of the nut is sweet, oily, and edible. The nut is enclosed by an indehiscent husk that contains a glandular pubescence on the surface. The fruit usually remains on the tree until after leaf fall (3).
