purple); glumes unequal, J to ^ the length of the long-awned palete, 
the lower mostly pointless, the upper more or less bristle-pointed; 
leaves convolute-bristle-form. — Sandy soil, W. New England (Con¬ 
necticut, Dana) to New Jersey, rare, thence southward and westward. 
Aug.—Pedicels V-2’ long, scarcely thicker than the awns, which 
are about 1' long. 
lO. BRACHYELYTBUM, Beauv. Brachyelytrum. 
Spikelets 1-flowered, with a conspicuous filiform pedicel of an 
abortive second flower about half its length, few, in a simple ap- 
pressed racemed panicle. Lower glume obsolete ; the upper mi¬ 
nute, pointless, persistent, shorter than the thick stalk of the 
flower. Pale© chartaceo-herbaceous, involute, inclosing the lin¬ 
ear-oblong grain, somewhat equal, rough with scattered short 
bristles ; the lower 5-nerved, contracted at the apex into a long 
straight awn ; the upper 2-pointed ; the awn-like sterile pedicel 
partly lodged in the groove on its back. Stamens 2 : the linear 
anthers and stigmas very long. — A perennial grass, with simple 
culms (1° - 3° high) from creeping rootstocks, rather downy 
sheaths, broad and flat lanceolate pointed leaves, and large spike- 
lets long without the awn. (Name composed of fipaxys, short, 
and eXvrpov , husk, from the very short glumes.) 
1. B. ariStatlim, Beauv. (Muhlenbergia er6cta, Schreb. Di-

11* CALAllIAOROSTIS) Adans. Reed Bent-Grass. 
Spikelets 1-flowered, and often with a rudimentary pedicel of a 
second abortive flower, in an open, contracted, or spiked panicle. 
Glumes keeled or boat-shaped, often acute, commonly nearly 
equal, and exceeding the flower, which is surrounded at the base 
by a copious tuft of white bristly hairs. Lower palea bearing a 
slender awn on the back or below the tip, rarely awnless ; the 
upper mostly shorter. Stamens 3. Grain free. — Perennials, 
with running rootstocks, and mostly tall and simple rigid culms. 
(Name compounded of Kakapoe, a reed, and dypotms, a grass.) 
§ 1. Calamagrostis proper. — Flower , fyc., nearly as in Agrostis, ex¬ 
cept the hairy tuft: the boat-shaped glumes and the palete membra¬ 
naceous ; the former equal or the loicer one rather longer : lower palea 
3 - 5-nerved, awned on the back : panicle open. (All the following 
have a rudimentary plumose pedicel.)
