Flowering specimens of a plant gathered by Barter on the Niger agree with this 
description, except in the flowers, which are borne in slender spikes. ‘The leaves also 
are not pubescent, but sparingly lepidote on both sides.

C. micranthum appears to me to be a small variety of C. altum, differing from it 
only in its smaller leaves and fruit.
