 G. cyperoides palustve, spica pendula. Loes. Pruss. 1 16. <. 30 ? 



In marshes, not uncommon. 



Perennial. April. 



Twice the size of the foregoing, with more of a glaucous hue. 

 Root creeping. Stems erect, from 1^ to 2 feet high, acutely 

 triangular, rough towards the top. Leaves erect, shorter than 

 the stems, the lower ones membranous, torn and reticulated at 

 the edge of their sheaths, which soon splits into entangled 

 threads, forming a kind of loose network. Bracteas leafy, 

 erect, taper-pointed • the upper ones very small, somewhat di- 

 lated and membranous at the edges, but without the dark 

 rounded auricles of C. ccespitosa. Fertile catkins from 1| to 2 

 inches long, all nearly or quite sessile, always upright, cylin- 

 drical, dense and many-flowered, most of them pointed, having 

 more or less of their upper part composed of barren Jiorets. 

 Scales obtuse, dark-brown, with a green rib. Barren catkins 

 often 2, besides the above-mentioned portions of the fertile ones, 

 an inch or two in length, with innumerable, obtuse, dark-brown 

 scales. Stam. 3. Stigm. 2, with a style nearly their own length. 

 Fruit like the preceding, but in 8 rows, rather more tapering 

 into its short notched beak, and falling off as soon as it is well 

 ripe. Seed orbicular, compressed. 



Mr. Davall observes that C. stricta, by means of its matted roots, 

 forms islands in the Swiss lakes or pools, probably like the tufts 

 of C. ccespitosa, on a larger scale. 



*#*** Barren and fertile jloreU in separate catkins. Bar- 

 ren catkins two or more. 



52. C. acuta. Slender-spiked Carex. 



Stigmas two. Catkins cylindrical, slender ; drooping in 

 flower ; afterwards erect. Fruit elliptical, with a blunt 

 undivided beak.
