Tetrathylacium is a genus of two species of shrubs and small trees in the family Salicaceae native to southern Central America and northern South America. Previously it was treated in the family Flacourtiaceae[1] but was moved along with its close relatives to the Salicaceae based on analyses of DNA data.[2] Tetrathylacium is rather unique in the Samydaceae in having tightly arranged panicles of spikes, four sepals and stamens, and non-arillate seeds.[3] The stems are often inhabited by ants, and T. macrophyllum is suspected to have locust pollination.[4]
