Very closely allied to £. atrovirens and agreeing with that species as regards the 
flowers in both sexes, but as a rule readily distinguishable by the shape of the leaf 
and the nature of the indumentum; the petioles are always longer in Z. oleracea 
than in its allies. Throughout the Congo State the leaves of this species appear to 
be in general use as a vegetable.
