384 ENDOGENOUS PLANTS 



VERTICILLATE SETARIA. 



Culm about 2 feet high, rather slender, smooth. Leaves 3 to 9 inches long; 

 sheaths smooth ; ligule bearded. Spike 2 to 3 inches in length ; rachis angular, 

 eulcate, scabrous ; spikelets clustered on short pedicels ; bristles about twice as long 

 as the spikelets, yellowish-green, sometimes purplish ; paleae of the perfect floret 

 roughish-dotted, or papillose. 

 Hab. Gardens, and lots : not yet very common. Fl. July. Fr. Aug. 



Obs. The adhesive bristles of this species are calculated to make 

 it something of a nuisance, if it becomes abundant. 



f f Bristles in clusters of 4 to 8 or 10, antrorsely scabrous. 



2. S. fflauca, Beauv. Spike tawny, quite cylindrical ; bristles 6 to 

 10 in a cluster, long ; paleae of the perfect florets transversely 

 rugose. 



GLAUCOUS SETARIA. Fox-tail Grass. 



Culm 2 to 3 feet high, smooth, sometimes branching, often several from the 

 same root. Leaves 6 to 15 inches long, somewhat glaucous ; sheaths smooth ; ligvle 

 short, fringed. Spike 2 to 6 inches in length ; rachis pubescent ; bristles 2 or 3 

 times as long as the spikelets ; perfect florets plano-convex the paleae firm and 

 almost horn like, wavy-wrinkled. 

 Hab. Stubble fields, orchards, Ac. : common. Fl. Aug. Fr. Sept. 



3. S. viridis, Beauv. Spike green, subcylindrical, or oval-oblong, 

 somewhat compound ; bristles 4 to 10 in a cluster, longish ; paleae 

 of the perfect florets striate lengthwise, puncticulate. 



GREEN SETARIA. Bottle-grass. 



Culm 1 to 2 or 3 feet high, often branching near the base. Leaves 3 to 8 inches 

 long ; sheaths smooth ; ligule fringed. Spike 1 to 4 inches long, often so compound 

 as to be swelling in the middle; rachis hirsute with short hairs; bristles 3 or 4 

 times as long as the spikelets. 

 Hab. Cultivated grounds ; roadsides, &c. : frequent. F Z.July. Fr. Aug. 



4. S. ITA"LICA, var. GERMANICA, Kunth. Spike yellowish, ovoid- 

 oblong, compound, interrupted at base ; bristles 4 to 8 in a cluster, 

 short ; paleae of the perfect floret smooth, minutely striate-punctate. 

 ITALIAN SETARIA (GERMAN VARIETY). Millet. Bengal-grass. 



Culm 2 to 4 or 5 feet high. Leaves 6 to 18 inches long, broadish ; sheaths striate; 

 ligule beard-like. Spike (or rather densely contracted panicle) 3 to 6 inches in 

 length ; rachis densely hirsute with longish hairs ; bristles about as long as the 

 spikelets. sometimes longer. 

 Hab. Fields : cultivated. Nat. of Europe, and India. Fl July. Fr. Aug. 



Obs. This is sometimes cultivated, to eke out the hay-crop ; but 

 it is not likely to become general, as a crop of Oats can be as 

 easily raised, and is more valuable, 



505. CEIV'CHRIIS, L. 



[Gr. Kenchros, the ancient name of Millet.] 



Spikelets as in Panicum, awnless, but inclosed (1 to 5 together,) in 

 a globular, bristly, or spinose involucre, which becomes coriaceous, 

 forming a deciduous bur, in fruit. Involucres sessile, in a terminal 

 spike. Scales none. Styles united below. Grain free, included in 

 the paleae.
