GRAMINEJS. (GRASS FAMILY.) 
spikelets in the same panicle. Glumes wanting-, or rudimentary 
and forming a little cup. Paleae herbaceo-membranaceous, convex, 
awnless in the sterile, the lower tipped with a straight awn in the 
fertile, flowers. Stamens 6. Stigmas pencil-form. Large and 
often reed-like water-grasses. Spikelets jointed with the club- 
shaped pedicels, very deciduous. (Adopted from Zi (dviov, the an¬ 
cient name of some wild grain.) 
1. Z. aqiustica, L. (Indian Rice. Water Oats.) Lower 
branches of the ample pyramidal panicle staminate, spreading; the up¬ 
per erect , pistillate ; pedicels strongly club-shaped ; lower paleu. long- 
aicned , rough; styles distinct; grain linear, slender. (Z. cla- 
vulosa, Michx.) — Swampy borders of streams and in shallow water, 
common, especially westward. Aug. — Culms 3° - 9° high. Leaves 
flat, 2 ? - 3° long, linear-lanceolate. Grain long; gathered largely 
for food by the Northwestern Indians. 
2. Z# miliacea, Michx. Panicle diffuse, ample, the staminate 
and pistillate flowers intermixed; awns short; styles united; grain 
ovate. 1 J.—Penn. ? Ohio, and southward. Aug. — Leaves involute. 
Z. fluitans, Michx., a Southern plant, was erroneously said to 
come from Lake Champlain, as the Michauxian herbarium shows, in 
which that locality is recorded for Z. clavulosa alone. 
3. AEOPECIIRITS, L. Foxtail Grass. 
Spikelets 1-flowered. Glumes boat-shaped, strongly compress- 
ed-keeled, nearly equal, united at the base, equalling or exceeding 
the lower palea, which is awned on the back below the middle: 
upper palea wanting ! Stamens 3. Styles mostly united. Stig¬ 
mas long and feathered. — Panicle contracted into a cylindrical 
soft spike. (Name from dXwnyf, fox, and obpd, tail, the popular 
appellation, from the shape of the spike.) 
L A. pratensis, L. (Meadow Foxtail.) Culm upright, 
smooth (2° high) ; palea equalling the acute glumes , which are unite 
below the middle; awn exserled more than half its length, twisted; 
upper leaf half the length of its somewhat inflated sheath. U 
troduced, common in meadows and pastures of New England. May* 
2. A. geniculatns, L. (Floating Foxtail.) Culm ascend- 
ing, bent at the lower joints; palea rather shorter than the obtuse glumes , 
the awn from near its base and projecting half its length beyond it > an 
thers linear; upper leaf as long as its sheath. 1J. — Moist meadows, 
rare, introduced ? July, August.
