: This species differs from C. schimperianus, Steud., only by the longer leaves. 
K. Schumann has finally arranged it (i.e. Volkens, 2276) as a variety of C. distans, 
Linn, f.; it differs from the black variety of that species by the stem being acutely 
triquetrous at the top, the broader spikelets, and especially by the nut being widened 
towards the top; but it is critically near.
