Etymology

The scientific name is taken from Sterculius of Roman mythology, who was the god of manure; this is in reference to the unpleasant aroma of the flowers of this genus (e.g. Sterculia foetida).

Ecology

Sterculia species are food plants for the larvae of some Lepidoptera species including the leaf miner Bucculatrix xenaula, which feeds exclusively on this genus.

Toxicity and uses

The pods, particularly those of S. foetida, contain seeds reported to be edible, with a taste similar to cocoa.[8] However, the oil contains cyclopropene fatty acids which could be carcinogenic or co-carcinogenic.[9]

Gum karaya is extracted from Sterculia species, and is used as a thickener and emulsifier in foods, as a laxative, and as a denture adhesive. In India, this is sourced from: Gujarat, Maharashtra, Madras, Madhya Pradesh and Chhota Nagpur.
