Irenodendron, A New Genus of Samydaceae From South America
Irenodendron (Samydaceae), a new genus for three species of shrubs and trees from South America, is described. Previously recognized as members of Laetia section Scypholaetia, these species (I. coriaceum, I. cupulatum, and I. ovalifolium) differ from Laetia sensu stricto in having cupular bracts, an apically divided style, and large rays in the wood. The wood anatomy and style morphology are similar to those of Ryania and Piparea (=Casearia sect. Piparea), to which we propose the new genus is closely related.
