Culm 6-15 inches higli, triquetrous, nearly smooth. Leaves about a line and a half wide, 

 somewhat rigid. Fertile spikes variable in number, but most frequently 3 - 4, rarely 5, half 

 an inch to an inch long; the lowest usually remote; the others often approximated : the 

 lower peduncles 6-10 lines long, with bracts at the base which are destitute of sheaths. 

 Fertile scales closely applied to the perigynium and equalling it in size, of a blackish brown 

 color, with a pale narrow margin and keel. Perigynium nerveless, 1 i line long ; the summit 

 produced into a very short beak. Achenium obovate, compressed-triquetrous, dull brown, very 

 minutely striate, crowned with the continuous style. Stigmas mostly 2. 



Summit of Mount Marcy, Essex county. Fl. July. Fr. August. This somewhat variable 

 plant is the C. saxa'ilis of most botanists, but (as has been ascertained by Dr. Boott) not of 

 Linnaeus. The original species proves to be C pulla, Gooden.; while the plant usually called 

 C. saxatilis, is C. rigida, Gooden. Numerous European specimens of the latter, in my 

 herbarium, agree very well with those from Mount Marcy.

Staminate spikes 1-3, cylindrical ; fertile spikes 2-4, distant, cylindrical, usually slender, 

 often staminate at the summit, spreading or somewhat nodding , the lower one on a short 

 peduncle, the others nearly sessile ; stigmas 2 ; perigynium ovate, with a short acuminalion, 

 smooth and nerveless, entire at the orifice, mostly longer and broader than the linear-oblong 

 blackish-ferruginous rather obtuse scale ; culm and leaves rough. — Boott in Hook. fl. Bor.-

Culms li - 3 feet high, growing in large thick tufts, sharply triquetrous and very rough 

 on the angles, leafy. Leaves somewhat glaucous, erect. Bracts without sheaths, rough like 

 the leaves, carinate. Staminate spikes most frequently solitary, but often 2 and rarely 3 ; the 

 terminal an inch or more in length ; the others shorter. Sterile scales oblong, obtuse. Fertile 

 ones from three fourths of an inch to two and a half inches long, and about two and a half 

 lines in diameter, dense, or the flowers rather loose and scattered toward the base : the lowest 

 one on a short peduncle, from a shealhlcss bracteal leaf; the others usually sessile, often 

 recurved ; sometimes all oblong-cylindrical, sessile and erect ; one or more of them staminate 

 at the sutnmit. Scales usually rather shorter than the perigynium, but sometimes longer, 

 blackish brown, with a green keel. Perigynium a little more than a line long, usually nerve-
