Dalechampia macrobractea, a New Species of Euphorbiaceae from Southern East Africa

Abstract

Abstract—Dalechampia macrobractea is a new species of Euphorbiaceae described from Tanzania and Zambia, Africa. It is similar to D. capensis due to having the deeply lobed leaves and three-lobed involucral bracts, but differs from this species in the size and shape of the leaves, number of pistillate bracteoles, and the absence of glandular trichomes on the margin of the pistillate bracteoles. We place it in Dalechampia sect. Dalechampia because the staminate involucel is two-lipped and the laminar staminate bracteoles are entire. Illustrations and comments about its geographical distribution and habitat are also provided.
