Oepbe 166.— GEAMINE^. 809 



hairy Ivs. and sheaths ; branches solitary, alternate, forming a contracted panicle ; 

 spikes usually in 4s, conjugate, terminal; gis. serrulate, longer than the hairs of 

 the pedicel ; perf. spkl. monandrous, and with a straight awn. — Damp pine bar- 

 rens about Charlestou (Elliott). 



7 A. sooparius Michx. Broom Grass. St. slender, paniculate, 3f high, branched, 

 one side furrowed, brandies solitary or 2 or S-fascieled, erect; Ivs. lance-linear, 

 somewhat hairy and glaucous ; spikes simple, lateral and terminal, oq long pe- 

 duncles, 2 — 3 from each sheath, purple; spikelets remote, abortive one neuteri 

 mostly subulate-awn ed, the hairs of its ped. as long as the g spikelet. — In dry fieldsi 

 forming tufts, U. S. and Can. 



8 A. H^lei. Culm rigid, 3 to 6f high, strict, with long, slender branches above, 

 each with a single terminal short (12 to 15",) spike; Ivs. long, rigid, rough-edged; 

 sterile spkl. i both gls. short-awned, ped. broad above, with stiff hairs shorter than 

 the fls. ; awn of the perfect fl. twisted. — S. TV. 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 B. of the Miss. 



70. SOR'GHUffl, L. Broom Corn, &c. Spikelets diffusely panicu- 

 late, in 2s or 3s on the slender, spreading branches ; the middle spikelet 

 complete, 2-flowered, the lower flower abortive, lateral spikelets sterile, 

 avvnless, 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 

 lOf; Ivs. lanceolate, acuminate, pubescent at base; pan. large diffuse, with long, 

 verticiUate, at length nodding branches ; gls. of the perfect spikelet hairy, persist- 

 ent. — (p The uses of this fine, cultivated plant are well known, if E. Ind. 



2 S. vulgare L. Indian Millet. Culm erect, round, solid with pith, 6 to 

 lOf; Ivs. carinate, lanceolate; pan. compact, oval, erect until mature; gls. and 

 pales caducous; fr. naked. — (I) Rarely cultivated as a curiosity, or for the seed as 

 food for poultry. J E. Ind. 



The Chinese Sugar Cane, recently in cultivation here, is probably a variely of 

 this species; also the African Millet, Imphee. Neitlier variety will yield a crys- 

 tallizable syrup, and cannot, therefore, rival the supremacy of the Southern Caue. 



71. COIX, 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 s&veral, remote from the fertile, all awnless ; grain roundish, 

 free. — Culm branched ; Ivs. broad, flat. 



C. L^oryma 1. Culm half terete ; sterile fls. naked ; fr. (ossified involucre) 

 ovoid. — ©Gardens. Plant 1 to 2f high, bushy, with lanceolate Ivs. Spikes 

 pedunculate, aggregated at the end of the sheathed branch. The curious fruit 

 is finally very hard, perforated, used by the children for beads.
