Indian almond Sterculia foetida, from here.

Belongs within: Malvaceae.

The Sterculioideae are a pantropical group of trees and shrubs with apetalous flowers. They were defined by Baum et al. (1998) as a node-based clade including Brachychiton paradoxum, Cola acuminata, Heritiera littoralis and Sterculia foetida. Sterculia species produce leathery (occasionally woody), dehiscent seed pods; the seeds of some species are edible. Dried fruits of the kola nut Cola acuminata are used as a flavouring. Brachychiton, bottletrees, is an Australasian genus including a number of species with thick trunks for storing water.

Characters (from S. R. Hinsley): Plants typically monoecious. Flowers apetalous (lacking petals), exinvolucellate (lacking an epicalyx), with a fleshy, usually petaloid, gamosepalous (fused) calyx, an absence of staminodes, a monadelphous staminal column, an androgynophore (a stalk separating the calyx from the stamens and styles), and apocarpous (i.e. separated) ovaries and fruits.
