S. Avenacea, Muhl. Descrip. Uber. Gram. 

 Clayton, p. 15. No. 621. (Elliot.) 



Two-coloured feather-grass, 



A very singular and beautiful graee from two to three feet 

 high. Along the borders and open parts of the woods on the 

 road from Camden to Woodbury. Not unfrequent. Peren- 

 nial. July, August. 



51. Andropogon, Gen. pi. 1566, ( Gramineae . )

 dite sessile : the masculine or neutral flow- 

 er, without awn and pedicellate. — Herma- 

 phrodite. Calix 2-valved, 1 flowered. 

 Corolla of 3 -valves ; the second valve smal- 

 ler and awned, the third interior minute. 

 Stamina 1 to 3. Receptacle or rachis most- 

 ly villous, bivolucrum, a fasciculate vil-

Avenaceus, 1. A. leaves and sheaths smooth, panicle naked 

 somewhat pyramidal-oblong many flowered, 

 flowers rufous triandrous, one valve of the glume 

 villous, awn very much contorted. 31ich. 



A. ciliatus, Elliot. 



A. nutans, Muhl. but not of Elliot, nor A. nutans 

 L. 



Fringed beard-grass. 



There appears to have been some confusion between this 

 species, and the A. nutans of Lin. ; and Dr. Muhlenberg con- 

 sidered them as identical. In his Descriptio Uberior Gram, 

 he has A. nutans, with the A. ciliatus of Mr. Elliot, and the 

 A. avenaceum of Michaux, as synonyms. But Mr. Elliot 

 himself describes the nutans, as distinct from his ciliatus. In 

 the grass intended above, which grows in profusion in Jersey, 

 and in the neighbourhood of Lancaster, I have never seen
