2. TWO NEW SPECIES OF EATONIA. 



EATONIA PUBESCENS Scribn. & Merrill sp. nov. 



An erect or ascending, tufted, pubescent perennial 4 to 8 dm. high, with linear 

 leaves and exserted contracted panicles. Culms densely pubescent below, 

 with short, spreading or reflexed matted hairs, sometimes nearly smooth 

 above ; nodes smooth ; sheathes shorter than the internodes, strongly striate, 

 densely pubescent, with hairs similar to those of the culm; ligule promi- 

 nent, generally hyaline, obtuse, somewhat lacerate, 3 mm. long, rather 

 densely pubescent on the back ; leaf -blades linear, 10 to 18 cm. long, 4 to 6 mm . 

 wide, slightly auriculate at the base, very strongly scabrous on both sur- 

 faces and margins, often somewhat pubescent beneath, with short spread- 

 ing hairs. Panicle lanceolate in outline, 10 to 18 cm. long, rather densely 

 flowered ; common axis sparingly pubescent ; branches erect or ascending, 

 the lower ones 5 to 6 cm. long. Spikelets 3 to 3. 5 mm. long, 2-flowered ; empty 

 glumes very uneciual, the first linear, scabrous on the keel, nearly 2 mm. 

 long, the second 2 to 2.2 mm. long, broadly obovate, obtuse or truncate, 

 scabrous on the keel and on the two faint lateral nerves ; flowering glumes 

 lanceolate, acute, sparingly scabrous at the apex, slightly punctate, sessile 

 one about 2.5 mm. long, the pedicellate one slightly shorter. 



Type specimen collected by S. M. Tracy at Starkeville, Miss., April 30, 1891,
