ORDER 156. GRAMINE^E. 809 



hairy Ivs. 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 Michx. BROOM GRASS. St. slender, paniculate, 3f high, branched, 

 one side furrowed, branches solitary or 2 or 3-fascicled, erect; Ivs. 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-awn ed, the hairs of its ped. as long as the 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",)spikft; Ivs. 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. 1 



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, &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 

 10f; Ivs. lanceolate, acuminate, pubescent at base; pan. large diffuse, with long, 

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

 ent. (J) 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 

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

 pales caducous ; fr. naked. (T) 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 ; Ivs. broad, flat. 



C. Lacryma L. 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 frnit 

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