short peduncles nearly included within the small sheathing bracts, 
or the lower partly exserted; and by the triquetrous fruit ; nu- 
merous, leafless, diffuse, and at length prostrate culms; and broad 
radical leaves. In the varying forms of C. anceps, the perigynium 
is constantly more obtuse on the angles, and more obovate in 
outline ; and the bracts are always long and leafy, the upper ex- 
ceeding the culm. In ©. digitalis, Wil/d., and the closely allied 
on much-exserted, filiform, more or less pendulous peduncles. 
The perigynium of the present species, the smallest of the group 
here indicated, closely resembles that of C. digitalis.

Culm about a foot high, leafy, smooth; spikes sessile, densely 
clustered, forming a compound capitate spike subtended by 3 
long unequal foliaceous bracts much exceeding the spike. Perl 
gynium tapering from an abruptly contracted ovate base into a 
long and slender scabrous bifid beak, a little exceeding the lan- 
ceolate abruptly mucronate scale. Achenium ovate, com 1 
crowned with the lengthened style. : 
is plant, which has a great resemblance to C. cyperoides, 
Linn., differs from that species in the nearly sessile perigymum, 
which tapers from a much wider and contracted (not attenuated) 
base into a shorter beak, of which the teeth are also shorter than 
in the European plant. The perigynia are more crowded on t 
rachis than in C. cyperoides, the spikes of which, owing to the 
greater length of the beaks, have a more comose appearance than 
in our plant. ‘The scale is shorter, abruptly nnn and not 
gradually tapering as in C. cyperoides; and the achemum 1S
