proposed to include the maritime plant here designated, — Sands of 

 the sea-shore from Maine to New Jersey. 



Var, APERTA, Boott, 111. 120, t. 385. 



G. tenera, Dewey, Sill. Journ. viii. 97, f. 9 (immature specimen). 



G.festucacea, Sartwell, Exsicc. no. 44. 



C tenera, var. majors Oluey, Exsicc. fasc. ii. no. 15. 



C. straminea, var. tenera, Bailey, Bot. Gaz. x. 381. 

 Spikes four or five, heavy, globular or broadly conical, separated, 

 bright tawny or rusty, disposed in a loose nodding head : perigyniura 

 inclining to be narrower than in other varieties. Transition to O. sco- 

 paria, with which it is often confounded, but from which the globular 

 and distinct spikes at once separate it. — Bogs and meadows from 

 Massachusetts to Oregon. Common eastward. Usually growing in 

 stools. 



Var. iNviSA, W. Boott, Bot. Gaz. ix. 86. 



Spikes small (about two lines broad), ovate, tawny, variously dis- 

 posed in dense or open heads, the lowest often very remote or on a 

 long subradical peduncle, the lower ones of the head subtended by 

 long and thread-like bracts (two to five inches long). Transition to 

 O. scoparia. — Common about Boston, Mass. ; Mt. Desert, Maine, 

 W. Boott ; salt marshes, Bombay Hook, Delaware, Commons. 



284. Carex leporina, Linn. Sp. PI. 973. 



C ovalis, Gooden. Linn. Trans, ii. 148. 

 Distinguished from erect forms of typical C straminea by the oblong 

 or cylindrical appressed spikes which are contiguous in a short head 

 (about an inch long), and the narrow and thin aj^pressed perigynium 

 which somewhat resembles that of 0. scoparia. Aspect intermediate 

 between C straminea and C. scoparia. — Said by W. Boott to be 

 established on Long Island in Boston Harbor. Europe. 



Var. Americana, Olney, Proc. Amer. Acad. 1872, 407. 

 C. petasata, Dewey, Sill. Journ. xxix. 246. 

 C. leporina, Bailey, Coulter's Man. 396. 

 Distinguished from the species by the narrow involute leaves, longer 

 perigynium, and general aspect. From the small and loose-headed 

 forms of C. /estiva it is distinguished by its narrow and rigid leaves, 

 which are much shorter than the culm. — Colorado, Utah, Oregon, and 

 British America. 



285. Carex Bonplandii, Kunth, Enum. Plant, ii. 380. 

 C. Purdiei, Boott, 111. 26, t. 67.
