The species of the genus Carex are exceedingly numerous and difficult of study. The one we have selected (Fif-, lO) is one of the commonest and « ae same uime one of the easiest to examine. In this genus the flowers are mona^cious, the separate kinds being either borne in different parts of the samo spike or in different spikes. The genus is dis- tinguished from all the others of this Order by the fact of the achene heAng encloned in a bottle-shaped more or less liijlated sac, which is made by the union of the edges of two inner bract- lets or scales. To this peculiar sac (Figs. 260 and 261) which encloses the achene the UAine perigyimini is given. The culms are always triangular and the leaves grass-like, usually rough- ened on the margins and on the keel. In the species under examination (which may be found in almost any wet meadow) the culm is some 18 Fi>. 201. inches high. The staminate spike (only one) is separate from and above the fertile one-;, which are 2 or 3 in number, few- (5 to 8) flowered, and quite near together. The perigynia are very much inflated, that is, very much larger than the achene ; they are distinctly marked with many nerves, and taper gradually into a long 2- toothed beak from which protrude the 3 stigmas. The bracts which subtend the spikes are leaf-like, and extend much beyond the top of the Fig. 259 Order rXI. GRAMIN'E.^. (CJrass Family.) Herbs somewhat resembling those
