8 A. Halei. Culm rigid, 3 to 5f high, strict, with long, slender branches above, each with a single terminal short (12 to 15",) spike,; lvs. long, rigid, rough-edged; sterile spkl. both gls. short-awned, ped. broad above, with stiff hairs shorter than the fls.; awn of the perfect fl. twisted. - S. W. States. A coarser plant than No. 7.
9 A. clandestina, with the soft, silky, white spikelets always concealed in a fascicle of sheaths, and
10 A. Neesii Kunth, with very slender glabrous spikelets almost concealed, are found in W. La., and possibly E. of the Miss. ,
70. SOR'GHUM, L. Broom Corn, etc. Spikelets diffusely paniculate, in 2s or 3s on the slender, spreading branches; the middle spikelet complete, 2-flowered, the lower flower abortive, lateral spikelets sterile, awnless, the pedicels smooth or merely pubescent; glumes coriaceous; pales membranous; stamens 3. - Stout Grasses, with solid culms.
1 S. saccharatum L. Broom Corn. Culm thick, solid with pith, 6 to 10f; lvs. lanceolate, acuminate, pubescent at base; pan. large diffuse, with long, verticillate, at length nodding branches; gls. of the perfect spikelet hairy, persistent. - The uses of this fine, cultivated plant are well known. ‡ E. Ind.
2 S. vulgare L. Indian Millet. Culm erect, round, solid with pith, 6 to 10f; lvs. carinate, lanceolate; pan. compact, oval, erect until mature; gls. and pales caducous; fr. naked. - Rarely cultivated as a curiosity, or for the seed as food for poultry. ‡ E. Ind.
The Chinese Sugar Cane, recently in cultivation here, is probably a variety of this species; also the African Millet, Imphee. Neither variety will yield a crys-tallizable syrup, and cannot, therefore, rival the supremacy of the Southern Cane.
71. CO'IX, L. Job's Tears. Spikelets 2-flowered, sessile, several in a spike which is involute at the base, the involucre closed around the lower (fertile) spikelet, becoming bony and polished; upper (sterile) spikelets several, remote from the fertile, all awnless; grain roundish, free. - Culm branched; lvs. broad, flat.
C. Lacryma L. Culm half terete; sterile fls. naked; fr. (ossified involucre) ovoid. - Gardens. Plant 1 to 2f high, bushy, with lanceolate lvs. Spikes pedunculate, aggregated at the end of the sheathed branch. The curious fruit is finally very hard, perforated, used by the children for beads.
Or Flowerless Plants. Vegetables destitute of true stamens and pistils, gradually descending to a mere cellular structure, with reproductive organs of 1 or 2 kinds, producing, instead of seeds, minute, dust-like bodies (spores) having neither integuments nor embryo.
Province, ACROGENS. Flowerless plants, having a regular stem or axis which grows by the extension of the apex only, without increasing in diameter, generally with leaves, and composed of cellular tissue and scalariform ducts. (Ferns, Mosses, Club-mosses, Horsetails, etc.)
