Abstract

A new genus of the Lauraceae, Yasunia van der Werff, is described. It consists of two undescribed species, Y. quadrata van der Werff and Y. sessiliflora van der Werff, known from lowland rainforest in Ecuador and Peru. The new genus is closely related to Beilschmiedia Nees, but differs in its conspicuous, pubescent staminodia, exserted stamens, and reduced number of stamens. The relationships of the new genus and its placement in the Cryptocaryeae are discussed.
