high, erect, from horizontal rootstock, often decumbent at base: sheaths 
shorter than the internodes, often crowded: ligules a ring of very short 
hairs: leaves 14-9 inches long, 1-2 lines wide, flat or involute: panicle 
dense and spike-like 1-3 inches long, the branches 1 inch long or less, erect: 
spikelets 6-16-flowered, 4-9 lines long, pale green or purplish: empty

40. CATABROSA Beauv. Agrost. 97, t. 19, fig. 8. 
Perennial grasses with soft flat leaves and open panicles. 
Spikelets usually 2-flowered. Two lower glumes empty, thin- 
membranaceous, much shorter than the flowering ones, unequal, 
rounded orobtuse at the apex. Flowering glumes membranous, 
erose-truncate. Palets barely shorter than the glume. Stam- 
ens 38. Styles distinct, with plumose stigmas. 
C. aquatica Beauv. Agrost. 157. Smooth and glabrous: stems erect, 
from a creeping base, 44-2 feet high, bright green, flaccid: sheaths usually 
_longer than the internodes, loose: ligule 144-5 inches long, 1-3 lines wide, 
flat, obtuse: panicle 1-8 inches long, open, the branches whorled, spread- 
ing or ascending, very slender 44-2 inches long, spikelets 114-134 lines 
long, the empty glumes rounded or obtuse, the first about half as long, as 
the second which is crenulate on the margins: flowering glumes 1-114 
lines long, 3-nerved, erose-trunate at the apex. In water or wet places, 
Washington to Alaska and Labrador to Nebraska: also Europe and Asia. 
41 GRAPHEPHORUM Desay. Bull. Soc. Philom. ii, 189. 
Erect grasses with flat leaves and usually contracted nodding 
panicles. Spikelets 2—4-flowered, flattened, the rachella prolong- 
ed beyond the flower. Glumes 4-6, the 2 lower ones empty, 
somewhat shorter than the flowering ones, thin-membranaceous, 
acute, keeled. Flowering glumes membranous, obscurely nerved, 
entire, sometimes short-awned just below the apex. Stamens 3. 
Styles distinct, with plumose stigmas. Grain glabrous. ~ 
G. Wolfii Vasey Des. Cat. Gr. U. 8.66. Stems slender, 15-30 inches 
high, from a perennial root: sheaths about as long as the internodes: 
ligules about a line long: leaves flat, scabrous, 6-10 inches long, 2-3 lines 
wide: lemany: erect, subspicate, 3-9 inches long: spikelets 2-4-flowered, 
pene : rachella villous: empty glumes elliptical, nearly equal, about 3 
ines long the first 1-nerved, the second 3-nerved: flowering glumes 2-244 
lines long, less than 1 line wide, obscurely 5-nerved, obtuse, lacerate, some- 
times split or 2-toothed, bearing an awn % line long: palets shorter than 
or nearly equalling the glumes. Dry rocky slopes, eastern Oregon to Mon- 
tana and California. 
42 PANICULARIA Fabr. Enum. Hort. Helmst. 373. (1763.) 
GLYCERIA R. Br. (1810.) 
Mostly perennial grasses with flat leaves and numerous spike- 
lets in more or less open panicles. Spikelets 2-20-flowered, terete 
or sometimes flattened. Two lower glumes empty, obtuse or 
acute, 1-3-nerved: flowering glumes membranous, rounded on 
the back, 5-9-nerved, the nerves disappearing in the hyaline apex.
