==Description== Plants in the genus Stachystemon are monoecious shrubs with simple, usually thickened, petiolate leaves with stipules at the base. The flowers are arranged singly or in small groups in upper leaf axils, often forming clusters on the ends of branchlets with bracts at the base. Male flowers are usually arranged on a pedicel, and usually have four to six tepals in two whorls, each male flower with seven to many stamens fused in a central column. Female flowers are more or less sessile, usually with four or six tepals, each flower with two styles. The fruit is a capsule containing a single seed with a caruncle.
