Green Quaking Grass (Briza Minor, L.)

The habitat of this plant is fields, dry sandy fields in the S.W., and cultivated ground. The habit is similar to that of the last. The stems are tufted, erect, and slender. The ligule is long and lance-shaped, acute. The panicle is similar to that of the last, but there are 7 florets in the spikelets, which are smaller, pale-green, and broader than long, or triangular. The glume is longer than the lowest florets. The lower palea is round or heart-shaped, cartilaginous, swollen along the back. The plant is 6-12 in. high, and flowers from June to August, being a herbaceous annual.

Annual Meadow Grass (Poa Annua, L.)

The habitat of this grass is fields, pastures, waste places, etc. The habit is prostrate below, then ascending', and the stem is rooting at the base, the root fibrous. The stems are flattened, the plant limp, bright-green, smooth, often bluish-green. The leaves are broad, blunt, wavy, linear, with the margin inrolled. The ligule is long and acute, the upper sheath longer than the leaf. The panicle is nearly pyramidal, with spikelets partly ranged all one way, green or purple, the branches spreading, twice divided, at an obtuse angle or horizontal, afterwards turned down. The spikelets are nearly stalkless, egg-shaped, with 5 florets. The lower palea is 5-nerved. The flowering glumes are smooth, the upper glumes broadest in the middle. There are 3 stamens. The 2 styles are short and terminal, the stigmas feathery. The fruit is 3-angled, grooved, enclosed in the glume. The plant is 3-12 in. in height. It is in flower from April to September. The plant is a herbaceous annual, but perennial on the Pyrenees and in India.

Smooth Meadow Grass (Poa Pratensis, L.)

The habitat of this grass is meadows, pastures, banks, etc. The habit is prostrate, then erect. The rootstock is creeping, with stolons. The round stem is smooth. The linear leaves are flat, acute, with a hollow tip. The sheath exceeds the upper leaves. The ligule is blunt and prominent. The panicle is spreading, with branches 3-5 times divided and rough, after flowering closed or open. The spikelets are egg-shaped, with 3-4 webbed florets. The lower palea has 5 prominent veins, 3 hairy. The plant is 1-2 ft. high. It flowers in June and July, and is a herbaceous perennial.

Rough Meadow Grass (Poa Trivialis, L.)

The habitat of this plant is meadows, moist and shady places, and damp woods. The habit is similar to that of the last, but there are no stolons. The stem is tufted, like the root, rough. The leaves are rough, and so are the sheaths, the upper longer than the leaf. The long ligule is acute. The panicle is erect, spreading, rough, and five times divided. The flowering glumes 3-5, webbed, the 5 nerves distinct, the spikelets egg-shaped. The plant is 1-2 ft. high. It flowers in June and July, and is a herbaceous perennial, in other essentials resembling the last.

Upright Brome Grass (Bromus Erectus, Huds.)

The habitat of this plant is fields, waste places on dry soil, sandy and chalky soils. The habit is prostrate below, then erect, the rootstock stout, creeping, without stolons. The stem is rigid, smooth, bent below. The leaves are hair)-, with inrolled margins, adapted to dry conditions, narrow, the radical leaves convolute, the upper broadest. The sheaths are hairy, with erect, scattered hairs. The ligule is short. The panicle is narrow, nearly erect, and simple, rigid, with 2-3 divided branches. The rachis is rough. The green or purple spikelets are linear lance-shaped, with numerous florets, flattened, distant. The flowering glumes are hairy, twice as long as the awn. The lowest glumes exceed the upper by one-third, the lower palea being faintly 7-veined. The style is lateral on the ovary, the anthers yellow. The plant is 1-3 ft. in height. It flowers from June to August, and is a herbaceous perennial.
