This is very close to C. amnicola, Kunth ; the steins are more bulbnis .it tlie 

 base and the nut narrower.

 V. 551. Glabrous. Stems 1 J-3 in. long, at the base woody and covered 

 by black fibres (fragments of leaf -sheaths). Leaves overtopping the 

 stems, y\- in. broad. Head 1, of 8-20 nearly sessile spikelets ; bracts 

 8-2, lowest up to 3 in. long, suberect, similar to the leaves. Spikelets

 boat-shaped, thin, ovate, hardly acute ; nerves 5, close to the keel, often 

 red-spotted, sides nerveless and colourless. Style short; branches :'.,

 suddenly contracted almost into a stalk, black-brown, glistening with 

 dots (i.e. the superficial quadrangular cells becoming scarious, finally 

 porose).

 Stems 4-16 in. long, robust or medium, thickened at the base by hard
