Sterculia is a genus of flowering plants in the mallow family, Malvaceae. It was previously placed in the now obsolete Sterculiaceae. Members of the genus are colloquially known as tropical chestnuts. 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).
