Dodonaea (hop bush; family Sapindaceae) A genus of shrubs and small trees with simple or pinnate, alternate leaves which are often sticky. The small, solitary flowers are in panicles, racemes, or clusters, usually white to red in colour, and often unisexual. The fruit is a large, membranaceous capsule, and 3- or 4-winged, similar to that of the hop, hence the common name. There are about 50 species, found in tropical and subtropical regions, and especially well represented in Australia.
