spikelets ovate-oblong, strongly com-

 mm. wide, often pink or purplish; 

 lemmas closely imbricate, nearly hori- 

 zontally spreading, strongly keeled,

14. Eragrostis capillaris (L.) Nees. 

 Lacegrass. (Fig. 199.) Annual; culms 

 erect, 20 to 50 cm. tall, much- 

 branched at base, the branches erect; 

 sheaths pilose, at least on the margin, 

 long-pilose at the throat; blades flat, 

 erect, pilose on upper surface near 

 the base, 1 to 3 mm. wide; panicle 

 oblong or elliptic, open, diffuse, 

 usually two-thirds the entire height 

 of the plant, the branches and branch- 

 lets capillary; spikelets long-pediceled, 

 2- to 4-flowered, 2 to 3 mm. long; 



glumes acute, 1 mm. long; lemmas 

 acute, about 1.5 mm. long, obscurely 

 nerved, rounded on the back, mi- 

 nutely scabrous toward the tip; 

 grain 0.5 mm. long, somewhat rough- 

 ened. O — Dry open ground, open 

 woods, and fields, Maine to Wis- 

 consin, south to Georgia, Kansas, 

 and eastern Texas. 



15. Eragrostis frankii C. A. Meyer. 

 (Fig. 200.) Resembling E. capillaris; 

 culms usually lower, spreading to 

 erect; sheaths glabrous except the 

 pilose throat; blades glabrous; panicle 

 less than half the entire height of the 

 plant, open but not diffuse, mostly 

 less than half as wide as long, the 

 branches ascending, the shorter pedi- 

 cels not much longer than the spike-

lets; spikelets 3- to 5-flowered, 2 to 

 3 mm. long. O — Sandbars, river 

 banks, and moist open ground, New 

 Hampshire to Minnesota, south to 

 Florida and Oklahoma. Eragrostis 

 frankii var. brevipes Fassett. Spike- 

 lets 5- to 7-flowered, 3 to 4 mm. 

 long. O — Wisconsin (Glenhaven) 

 and Illinois. 



16. Eragrostis pilosa (L.) Beauv. 

 India lovegrass. (Fig. 201.) Weedy 

 annual; culms slender, erect or as- 

 cending from a decumbent base, 10 

 to 50 cm. tall; blades flat, 1 to 3 

 mm. wide; panicle delicate, open, 

 becoming somewhat diffuse, 5 to 20 

 cm. long, the branches capillary, flexu- 

 ous, ascending or spreading, finally 

 somewhat implicate, the lower fas-
