This is very close to C. amnicola, Kunth; the stems are more bulbous at the 
base and the nut narrower.

v. 551. Glabrous. Stems 14-3 in. long, at the base woody and covered 
by black fibres (fragments of leaf-sheaths). Leaves overtopping the 
stems, 5, in. broad. Head 1, of 8-20 nearly sessile spikelets; bracts 
3-2, lowest up to 3 in. long, suberect, similar to the leaves. Spikelets 
} by 4/5 in., compressed, 20-flowered, pallid, with parallel sides. Glumes 
boat-shaped, thin, ovate, hardly acute; nerves 5, close to the keel, often 
red-spotted, sides nerveless and colourless. Style short; branches 3, 
long. Nut hardly half the length of the glume, trigonous-globose, 
suddenly contracted almost into a stalk, black-brown, glistening with 
dots (ie. the superficial quadrangular ce)ls becoming scarious, finally 
porose).

thickened by tough torn dusky straw-coloured sheaths, Leaves 3 the

This came to hand marked Cyp. macropus (i.e. Mariscus macropus below), 
to which the base of the stems and heads bear a very general resemblance. The 
€xamples are young, but hardly differ from the Indian C. niveus, Retz.

Stems 4-16 in. long, robust or medium, thickened at the base by hard 
black-brown (not fibrillose) leaf-sheaths, contiguous, fused into a short 
horizontal rhizome. Leaves as long as the stem, or sometimes much 
shorter, =,—1 in. broad. Head 1, of 5-20 spikelets, }-1} in. in diam., 
dirty straw-coloured or yellowish (but see var. flavissima) ; bracts 3-4, 
lowest 2-4 in. long, similar to the leaves, spreading, dilated at the base. 
Spikelets 4-2 by 1-1 in., broad oblong or ovoid, compressed, 8-18-
