    ORCHIS MASCULA : Male Orchis. Petaloid Endogens. Nat. Order, Orohidaoeie, or Orchids. Roots fleshy, simple, partly fibrous, partly testiculate, undivided. Leaves radical, deep green, shining, oblong-lanceolate, usually blotched with dark purple, paler on the underside. Scape longer than the radical leaves, spotted with purple, with two or three sheathing leaves. _ Flowers purple, with a few crimson spots, in a long cylindrical spike. Bracts lanceolate, acuminate, shorter than the ovary. Sepals 3, oblong; the lateral reflexed, the dorsal erect. Petals smaller than the sepals, but of nearly the same form, erect, arching over the column. Lip 3-lobed, crenulate or serrate, the lateral lobes rounded, the central retuse; spur cylindrical, obtuse, nearly horizontal, as long as the ovary. Column very short, with a tubercle on each side. Anther erect, apiculate, dehiscing in front; pollen masses 2, sectile, each with a long caudicle attached to a gland con- cealed within a common stigmatic pouch. Ovary inferior, twisted, 1-celled, with 3 parietal polyspermous placentae. Stigma concave, transverse, immediately beneath the pouch. BROMUS MOLLIS: Soft Brome Grass. Glumaceous Endogens. Nat. Order, GRAHiNACEiE, or Grasses. Roots fibrous, few and weak. Stems erect, ascending, from 1 to 2 feet high. Leaves narrow, clothed with long soft hairs, especially on the sheaths, which are shaggy ; ligula very short. Spikelets in an erect downy raceme, on erect elastic pedicels usually placed in pairs, long, narrow, slightly compressed, many-flowered. Glumes 2, thin, acute, the lower with 3, the upper larger with 5 obscure ribs. Pales 2; the lower oblong, bidentate, about 7-ribbed, with a setaceous awn from below the point externally; the upper linear, membranous, obtuse, with green fringed edges. Stamens 3 ; stigmas 2, plumose. POA ANNUA : Annual Meadow Grass. Glumaceous Endogens. Nat. Order, Grahinace2e, or Grasses. Root fibrous. Stems several, pale, very smooth, somewhat compressed, leafy, jointed, branched at the base, spreading in every direction, and taking root at many of their lower joints ; their length from 3 to 12 inches. Leaves of a fine light green, spreading, linear, bluutish, flaccid, flat, except a crumpled portion here and there; sheath long, compressed, smooth; ligula oblong, acute or obtuse, and jagged. Panicle loose, rather longer than the leaves when full grown, with a somewhat secund and rather triangular outline. Spikelets narrow, compressed, ovate, externally smooth, 5-6-flowered. Glumes ovate, acute, the upper rather larger than the lower. Pales 2 ; the lower deep green tinged with purple, ovate, obtuse, membranous at the margin; the upper narrower, bidentate, with the edges turned inwards. i^tamens 3,^ hypogynous, with weak Jj)jfoppr*£4gments and versatile linear anthers 2-lobed at each end.
