Var. CONDENSATA. (Aristida condensata Chapm.) Culms stout, simple, 2 or 3 feet

long; floral glume very slender, linear, nearly 1 inch long to the division; awns nearly 
equal, widely spreading, about 1 inch long.—South Carolina to Florida. 
10. A. palustris Vasey. (A. virgata var. (?) palustris Chapm. Fl. 8. States, p. 555.) 
Perenial, tufted, culms 3 to 5 feet high, rigid, erect; leaves very long, 1 to 2 feet, 
sometimes involute, flat below; panicle 14 to 2 feet long, narrow, spike-like, branches 
appressed, the lower 2 to 3 inches long, sessile; glumes nearly equal, about 5 to 6

11. A. virgata Trin. Acta Petrop, 1829, p.86. Perennial? Culms 1} to 2 feet 
high; simple leaves, narrowly linear, flat, 3 to 6 inches long; panicle spike-like, nar- 
row; lower branches appressed, somewhat distant, in twos or threes, one short, the 
other 1 to 2 inches long; empty glumes, 3 to 3} lines long; flowering glume, 2 lines 
long; smooth, stipe very short and sharp-pointed; middle awn about 6 lines long, 
lateral ones about 4 lines. 
This species was included in Chapman’s Flora of the Southern States, but has not 
recently been in the South, neither has it been recognized at the North, although 
Trinius describes it as from Philadelphia, but specimens collected at Point Norris, New 
Jersey, last summer, by Mr. Jesse H. Holmes, answer fairly to this description and 
seem to be intermediate between A. gracilis and small forms of A. purpurascens or of 
A, stricta. 
12, A. bromoides H. B. K. Nov. Gen. 1. p. 100. (A dispersa Trin. var. brom- 
oides). Culms 10 to 18 inches high, commonly much branched, forming close tufts, 
slender; radical leaves few and short, those of the culm 2 or 3,1 or 2 inches long, 
involute-setaceous, sheaths shorter than internodes; panicle 1 to 3 inches long, 
spike-like, erect or secund, the branches solitary or clustered, flowering nearly to the 
base ; glumes unequal, the lower 2 lines and upper 3 to4 lines long, 1-nerved ; flowering 
glume 3 to 4 lines long with white hairy callus; awns about equal, 3 to 5 lines long.— 
Texas, New Mexico, Arizona, South Carolina and Mexico. 
This is a pretty distinet form in general, but frequently becomes large and branch- 
ing and verges into 4. dispersa Trin.
