Order 166.— GRAMINE-*. 809 



hairy lv& and sheaths ; branches solitary, alternate, forming a contracted panicle ; 

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

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

 rens about Charleston (Elliott). 



7 A. scoparius Miehx. Broom Grass. St. slender, paniculate, 3f high, branched, 

 one side furrowed, branches solitary or 2 or 3-fascicled, erect; lvs. lance-linear, 

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

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

 mostly subulate-awued, the hairs of its ped. as long as the 5 spikelet. — In dry fields, 

 forming tufts, U. S. and Can. 



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. shori-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, silk}-, 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, &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, 



•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 

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

 verticillate, at length nodding branches; gls. of tiie perfect spikelet hairy, persist- 

 ent. — Q) 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 

 I Of; lvs. carinate, lanceolate; pan. compact, oval, erect until mature; gls. and 

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

 food for poultry. \ E. Ind. 



The Chinese ScGAtt Cane, recently in cultivation bere, is probably a variety of 

 this species; also the African Millet, Imphee. Neither variety will yield a crys- 

 tailizable syrup, and cannot, therefore, rival tbe supremacy of the Southern Cane 



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 several, remote from the fertile, all awnless ; grain roundish, 

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



C. Lacryma L. Culm balf terete; sterile fls. naked; fr. (ossified involucre) 

 ©void. — (D 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 bard, perforated, used by tho children for beads.
