124 MONOECIA— TRIANDRIA. Carex. 



Seed small, sessile, triangular, short, not near filling the cavity, 

 crowned with the long permanent style. 

 The two varieties of Linnaeus, quoted above, are merely different 

 stages of the fructification ; his /3 is C. sylvatica, totally unlike 

 vesicaria. 



57. C. ampullacea. Slender-beaked Bottle Carex. 



Fertile catkins cylindrical, elongated, nearly sessile. Scales 

 all lanceolate, acute. Sheaths none. Fruit inflated, glo- 

 bose, with a linear cloven beak.

Perennial. May. 



Root creeping. Stem 1 or 2 feet high, with 3 blunt angles, smooth, 

 except above the lowermost bractea. Leaves narrower than the 

 foregoing, erect, somewhat glaucous, acute, rough at the edges 

 and keel near the extremity. Bracteas very narrow, with no 

 sheaths, except the lower one. Barren catkins 2 or 3, much 

 like the last j fertile with similar short stalks, but otherwise very 

 difterent, nearly twice as long, and scarcely above half so thick, 

 upright ; their scales lanceolate, acute. Stam. 3. Stigm.S, with 

 a longish style. Fruit copious and crowded, longer than the 

 scales, half the size of C. vesicaria, moderately spreading, in- 

 flated, almost globular, ribbed, smooth, yellowish, abruptly 

 tipped with a linear beak, cloven at the extremity. Seed small, 

 sessile, elliptical with 3 angles, crowned with the style. 



The fruit of this species resembles a bottle or flask, ampulla ; that 

 of the last a bladder, vesica ; so that they ought never to have 

 been confounded in character or name j to say nothing of the 

 totally difterent shapes of their catkins when ripe.
