84 New and rare Plants of North Carolina. 



lateral awns short, the intermediate very long, the interior valve 



short awned. 



Stems 2-2£ feet high, forming large tussocks ; leaves overtop- 

 ping the culm, subulately attenuate ; pedicels 1-1J inch long ; 

 awns of the calyx unequal, the longest about two thirds the 

 length of the awn of the corolla, which is an inch or more long ; 

 the lateral awns of the corolla are merely the disengaged sides of 

 the summit of the valve. Habitat, sandy soil of the sea islands 

 of North Carolina ; also East Florida. — Flowers last of Septem- 

 ber-October. 



This may be a variety of M. Polypogon, Trin. ; if so, there 

 are probably no characters by which either may be separated 

 from M. capillaris, Trin. 



Carex Mitchelliana : spikes in threes, peduncled, somewhat 



distant, oblong, subnutant j terminal spike staminate at the base 



and summit; the lowest peduncle scarcely sheathed; capsule 

 ovate, acute, glabrous ; scales oblong, the lowest with a long 

 cusp much exceeding the fruit, the upper about equalling it. 

 Habitat, wet places, Chatham County. — Flowers in May. 



Stem 18 inches high, slender, acutely triquetrous, smooth, 

 except at the summit ; leaves shorter than the culm, smooth, ex- 

 cept toward the tip; terminal spike staminate more than half 

 its length, and a few staminate flowers at the summit as in the 

 other spikes; spikes about an inch long, not very crowded; 

 scales of the fruit at the base of the spike with a subulate point 

 about a third longer than the capsule, but diminishing in length 

 toward the summit, where they are about equal to and some- 

 times shorter than the capsule. 



This is a distigmatic species and belongs to the same group 

 with C. ainita. — Discovered in 1835. 



Carex glaucescens, (?. androgyna : spikes 4-5, erect, large, 



cylindrical, terminal one androgynous, (staminate at base,) the 

 rest fertile. 



Stem rigid, 3-4 feet high ; spikes thick, 2£-3 inches long. 

 This is an autumnal variety, flowering in October, and much the 

 handsomest species I am acquainted with. Habitat, wet ground, 

 Wilmington, N. C. 



This species appears to be quite polymorphous. In its com- 

 mon form it has but one staminate spike ; but it sometimes has 

 two or more, and is then C. verrucosa, Ell. 



Hillsborough, N.C., Nov. 1, 1842.
