A very distinct species, unlike any other from Tropical A frica 
that I have seen 3 atin, perhaps, nearest allied to E. dracunculoides, 
Lam., but the 3-toothed leaves and very different glands of the 
involucre readily distinguish it. In general appearance it may | 
likened to E. macra, Hiern, from which it abundantly differs in its 
annual habit and broader 3-toothed leaves.

This would appear to be a rare plant. Tt was originally discovere 
in 1837, near El Obeid, in Cordofan, by Kotschy, and the species 
was founded upon his specimens ; no other collector, so far as a 
aware, has again found the plant until Captain and Mrs. Lugar 
ciently conspicuous wherever it is present. However, its discovery 
in Ngamiland is an interestin one, and widely extends its range. 
pecifically, it is nearly allied to E systyla, Edgew., differing in its 
angular stem, serrate leaves (which are remarkably winged along 
the midrib beneath), and in the villous fruit.
