Paspalum Michauxianum Kunth, Rev. Gram. 25. 1829. Culms erect, 4/-20 tall, extensively creeping at the base. Sheats smooth, sometimes ciliate on the margins, or sparsely pubescent; blades flat, ii'-s' long, i"-3" wide, acuminate, smooth; racemes 1'- 2i' long, in pairs, or occasionally with a third, the rachis flat, 4"-i" wide, smooth; spikelets ii"-ii" long, ovate, acute, nearly sessile in 2 rows, the outer scales S-nerved, the first glabrous, the second ap- pressed-pubescent, the acute third sparingly bearded at the apex. On the seashore or along rivers, Virginia to Mis- souri, California and Washington, south to Florida, Texas and Mexico. Also in tropical America. Sept. Knot-grass. Devil's-grass. 16. ECHINOCHLOA Beauv. Agrost. 53. 1812. Usually tall grasses, commonly annuals, with broad leaf-blades, and a terminal inflores- cence consisting of i-sided racemes. Spikelets i-flowered, singly disposed, or in smaller racemes or clusters on the ultimate divisions of the inflorescence. Scales 4, the outer 3 membranous, hispid on the nerves, the third and usually also the second scale awned or awn- pointed, the awn often very long, the fourth scale indurated at maturity, shining, pointed, the margins thick and inrolled, enclosing a palet of similar texture, which is free at the tip, and a perfect flower.
