and woodlands, Va. (according to T. H. Kearney, Jr.) to Fla., the Ind. 

 Terr, and Tex. Aug. and Sept. Differs from E. capillaris in its stouter 

 and taller culms, strongly papillose-hispid sheaths, and elongated leaves. 



P. 131, after Eragrostis secundiflora Presl, insert: 



12a. Eragrostis capitata (Nutt.) Nash. Culms branching and creeping, 

 rooting at the nodes, which send up branches 6-10 cm. long; sheaths, at least 

 those on the branches, pubescent; leaves spreading or ascending, 1-3 cm. 

 long. 1.5-3 mm - wide, flat, lanceolate, pubescent; panicle 2-3 cm. long, 

 nearly or quite as broad, oval; spikelets crowded, clustered, 12-30- 

 flowered, 6-14 mm. long. (Poa capitata Nutt.) In sandy, usually wet soil, 

 Ark. and La. to Neb., N. Mex. and Tex. Also in Mexico. June-Aug. 

 Differs most prominently from E. hypnoidcs (Lam.) B.S.P. by its longer 

 pubescent flowering scales. 



P. 132, in Eatonia obtusata (Michx.) A. Gray, third line, omit the 

 words "sometimes pubescent"; add: 



ia. Eatonia pubescens Scribn. & Mer. Hairy Eatonia. A tufted per- 

 ennial, with the sheaths, back of the ligule and lower part of the culm 

 softly and densely pubescent. Culms 3-8 dm. tall; leaves 5-18 cm. long, 

 3-6 mm. wide, glabrous, or often softly pubescent; panicle 5-20 cm. long; 

 spikelets 2.5-3.5 mm. long. In dry soil, Conn, to Penn., Ga. and Tex. 

 May- Aug. Differs from E. obtusata in having the sheaths, and often 

 also the leaves and culms, softly pubescent. 



After Eatonia nitida (Spreng.) Nash, insert: 



3a. Eatonia glabra Nash. Smooth Eatonia. Clums densely tufted, 

 Blender, 3-7 dm. tall; sheaths glabrous; leaves rough, flat, 2-7 cm. long, 

 1.5-3 mm. wide; panicle 7-15 cm. long, slender, nodding at the sum-

 July. The glabrous sheaths and leaves separate this from E. nitida. Type 

 collected in Madison Co., Tenn., by S. M. Bain, Apr. 1893, No. 507. 



P. 135, after Uniola laxa (L.) B.S.P., insert: 



ia. Uniola longifolia Scribn. Hairy-sheathed Uniola. Culms tufted, 

 8-12 dm. tall; sheaths, at least the lower ones, densely hirsute; leaves flat, 

 3 dm. long or less, narrowed at both ends, 6-12 mm. wide; panicle 2-4.5 

 dm. long, its branches short and appressed, or the lower ones sometimes 

 long and ascending; spikelets 3-4-flowered, usually about 6 mm. long, the 

 flowering scales about 5 mm. long. In dry, usually sandy soil, Tenn. to 

 Fla. and La. Aug. and Sept. Distinguished by its larger size and strongly 

 hirsute sheaths. 



P. 156. in Elymus striatus Willd., sixth line, omit the words "rough, 

 hispid or"; add: 



ia. Elymus Arkansanus Scribn. & Ball. Arkansas Wild Rye. Culms 

 slender, erect, 6-9 dm. tall; sheaths ciliate on the margin; leaves 1-2 dm. 

 long. 4-8 mm. wide, erect or ascending, auricled at the base, rough on the 

 lower surface, the upper surface finely and densely pubescent; spike long- 

 exserted, nodding, 6-9 cm. long: spikelets 2 at each node, 2-flowered; 

 empty scales linear-subulate, hispidulous and 2-3-nerved above, 8-10 mm.

 hispidulous, about 7 mm. long, ending in a straight awn 2-4 cm. long. In 

 woods, Ia. to Ark. and Mo. July. Differs from E. striatus in having the 

 empty and flowering scales merely hispidulous. 



P. 157, after Elymus hirsutiglumis Scribn. & Sm., insert:
