GRAMINEiE. (GRASS FAMILY.) 
* * * Spikelets linear -1' long), pale, oppressed on the branches of 
the racemose-elongated panicle : palece minutely roughish ; the upper 
2-toothed : stamens 3: ligule long : culm flattened , ascending from a 
rooting base. 
7. <x. fluitailS, R. Brown. Spikelets 7 -13-flowered ; loicer 
palea oblong , obtuse , slightly eroded at the apex, usually rather longer 
than the blunt upper one. — Shallow water, common. June. — Culm 
thickish, 2°-5° long. Leaves short and rather broad, very smooth. 
Panicle 1° long: the simple branches appressed, finally spreading 
below. 
8. G. acutiflora, Torr. Spikelets 5-12-fiowered, few and 
scattered on the nearly simple panicle ; lower palea oblong-lanceolate , 
acute , shorter than the long tapering point of the upper one. — Wet 
places, rather rare. June. — Resembles the last; but the erect leaves 
smaller, the separate flowers twice the length ($' long) and less dis¬ 
tinctly nerved. 
20. SCLEROCHLOA, Beauv. ScLEROCHLOA. 
Spikelets, flowers, &c., much as in Glyceria, but the convex 
lower palea with 5 faint though distinct parallel nerves, charta- 
ceous below, scarious at the obtuse (sometimes denticulate or mu* 
cronulate) tip/ Stamens 3. — Sea-side or saltrmarsh grasses, 
with the almost cylindrical spikelets appressed to the branches of 
the contracted or expanding panicle. (Name composed of <tkKi)~ 
p6s y rigid , and ^Ada, grass, from their general rigidity.) 
1- S. aresiaria, Nees. (Sea Spear-Grass.) Spikelets short- 
pedicelled, or almost sessile along the branches of the somewhat sim¬ 
ple open panicle, 3- 8-flowered, linear or oblong-linear; flowers mi¬ 
nutely bearded at the base. 1J. (Poa arenaria, Relz , Trin.) —Var. 
1. maritima has branches of the panicle spreading when young but 
appressed-contraded in fruit, spikelets to §' long, and the pale rigid 
leaves involute; rootstock somewhat creeping. (P. maritima, Huds.) 
— Var. 2. fasciculata, ex Trin. (P. fasciculata, Torr.), is a state 
with smaller spikelets, panicle of clustered brandies, flat leaves, and 
fibrous roots. — Salt marshes along the coast. June-Aug. — Usu¬ 
ally purplish-glaucous in flower, l°-2? high. — Distinguished from 
Festuca by the free grain, &c. 
30. BRIZOPYRUifl, Link. Spiked Quaking-Grass. 
Spikelets and numerous flowers compressed, crowded in a 
densely spiked or capitate panicle. Glumes herbaceous or mem¬ 
branaceous, the lower several-nerved. Lower palea chartaceo-
