The monotypic Philippine genus Gongrospermum Radlk. (Sapindaceae)

Abstract

The rare Philippine genus Gongrospermum Radlk., containing the single species G. philippinense Radlk., is described. The genus can easily be distinguished from similar looking genera like Dimocarpus, Glenniea, and Trigonachras on the basis of the absence of petals, the fruits which are glabrous inside, the absence of an arilloid and the ruminate endotesta.
