This species differs from C. s chimp erianus^ 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.

It may possibly be a subalpine depauperated state of C. aterrimus. 



S9. C. maranguensis, A". iS'cA^/m. in Engl. Pfl. Ost-Afr. C. 120. 

 Glabrous. Stem 2 ft. high, at the base erect from a woody rhizome, 

 at the top trigonous. Leaves as long as the stem, up to J in. broad. 

 Umbel 7 in. in diam., compound ; bracts 5, lowest nearly 1 ft. long, 

 similar to the leaves. Spikes loosely spicate, of 12-15 spikelets. 

 Spikelets lurid green, up to f by -j^ in., .10-16-flowered ; wings of 

 rhachilla oblong, persistent. Glumes elliptic, obtuse, distant. Style 

 short ; branches 8, shortly exserted from the glume. Nut | the length 

 of the glume, oblong ellipsoid.

This species appears from the unusual black-green colour of the spikelets very 

 distinct. The example is not fully ripe; the lower empty glume has a long tail, 

 the upper empty glume has a short poiut ; from this 1 think it not improbable that 

 the species may prove a Mariscns near M. eurystaehys and M.foliosus. 



Var. ferrugineoviridis, C. B. Clarke. Stolons numerous, stout. Stem at the 

 l)ase erect, at the top thick, fluted. Leaves and bracts numerous, broad. Glumes 

 green on the back, ferruginous on the sides.
