Abstract

Dalechampia macrobractea is a new species of Euphorbiaceae described from Tanzania and Zambia, Africa. It is similar to D. capensis due the division of folioles and 3-lobed involucral bracts, but differs from this species by the size and shape of leaves, number of pistillate involucellar bracts and absence of glandular trichomes in the margin of the pistillate involucellar bracts. We place it in Dalechampia sect. Dalechampia because the staminate involucel is 2-lipped and the laminar staminate bractlets are entire. Illustrations and comments about its geographical distribution and habitat are also provided.
