Perennial. July. 



Root tufted, short and thick, slightly creeping, with copious, 

 shaggy, pale, yellowish, very long fibres, but no runners. Stem 

 3 or 4 inches high, erect, triangular, smooth, leafy at the bottom 

 only. Leaves short, upright, ribbed, taper-pointed, smooth, 

 except at the edges near the extremity. Catkins 3, all stalked, 

 ovate, of a dark chocolate-colour, as if scorched, each with a 

 small, slightly sheathing, bractea, of nearly the same hue ; the 

 2 fertile ones pendulous, dense, many-flowered, with ovate, 

 acute, slender-keeled scales. Stam. 3. Stigm.3. Fruit trian- 

 gular but compressed, elliptical, dark brown, without ribs ; pale 

 at the base ; rough-edged in the upper part ; ending in a short, 

 broadish, cloven beak. 



A Lapland specimen of this very distinct species was, by Linnaeus 

 in his herbarium, mistaken for C. atrata, and I have the same, 

 named atrata, from Dr. Swartz. 



35. C. atrata. Black Carex. 



Sheaths scarcely any. Catkins uniform, stalked, ovate, 

 drooping ; the terminal one with many barren florets 

 below. Fruit elliptical, compressed, smooth, with a 

 notched beak. Stamens two or three.
