Eragrostis major, Host, Gram. Austr. iv, 14 (1809). 
The common low, nearly prostrate form was found in roads and old fields: Mullen, 
July 20 and September 17; Thedford, September 7 (No. 1588). Another form, nearly 
upright and with many broad leaves, was found in fields: Forks of Dismal River, 
July 11; Natick, September 7 (No, 1522). 
Eragrostis caroliniana (Spreng.) Seribn. Mem. Torr. Club, v, 49 (1894); Poa 
caroliniana Spreng. Mart. Fl. Hal. i, 33 (1807). 
This has been confused with F. pilosa, trom which it is very hard to distinguish 
it. Perhaps only a Western form of that species. Railroad embankment: Mullen, 
September 15 (No. 1774). 
Eragrostis tenuis (Ell.) Gray, Man. ed. 2, 564 (1856); Poa tenuis Ell. Bot. S. Car. 
and Georg. i, 156 (1817). : 
This is one of the blowout grasses, growing on the drier sand hills. It is one of 
the most common plants in the region, and is very variable, its character probably 
depending upon the conditions under which it grows. A form with strict, elongated 
panicle, with many large spikelets, I take as typical. This has broad leaves, about 
4mm. wide, and conspicuous tufts of hairs at the mouth of the sheath: Cody’s 
Lakes, August 10 (No. 1829). Another form with large, spreading panicle and long, 
involute leaves was collected at Thedford, September 13; Plummer Ford, August 22 
(No. 1831). A third form was like the typical except that it was much smaller, its 
panicle small with comparatively few spikelets: Plummer Ford, August 23 (No. 
1832). Near Mullen, July 18, a form was met having few-flowered (mostly 1- to 3- 
flowered) spikelets, with probably abortive flowers (No. 1569). This is, according 
to Professor Scribner, the variety terensis Vasey. 
Eragrostis pectinacea (Mx.) Steudel, Syn, Pl. Gram. 272 (1855); Poa pectinacea 
Mx. FI. i, 69 (1803). 
A really ornamental grass with its large panicle of spikelets of a brilliant red 
color: Thedford, August 19; Plummer Ford, August 23 to 26 (No. 1711). 
Poa pratensis L. Sp. Pl. i, 67 (1753). 
Two distinct forms which probably belong to this were collected. One resembles 
the common form cultivated for lawns, but has smaller spikelets. Prairies, Thed- 
ford, June 14 (No. 1275). The other is a tall grass, which looks very different from 
the ordinary one. The panicle is denser, the branches less spreading, the spikelets 
large, the empty glumes scabrous on the margin, and the leaves longer and broader. 
Meadows, Thedford, June 14; Plumer Ford, July 4 (No. 1278). 
Poa sp. 
Differs from P. fendleriana (Stend.) Vasey! in not being a bunch grass, in the more 
hairy glumes, which have a narrower searious portion, and in the long and broad 
leaves (1 to 2 dm. long and 5 mm. broad). The latter resemble much those of Poa 
‘Tl. N. A. Grasses, ii, 94 (1893); Stend. Syn. Gram. 278, 1855.
