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

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

 an inch to an inch long ; ihe lowest usua'ly remote ; tiie oihers often approximated : the 

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

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

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

 produced into a very short beak. Aciienium 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 

 Linnasus. The original species proves lobe 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 sliort 

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

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

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

Culms 15-3 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 sheathless bracteal leaf; the others usually sessile, often 



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



at the summit. Scales usually raiher shorter than the perigynium, but sometimes longer, 



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