Culm 1-2 feet high, slender, flaccid, subprostrate, leafy to- 
wards the root; leaves narrow and long; spikelets ovate, round 
or subglobose, remote, sessile, 2 to 6-flowered, staminate above,

_ This plant agrees with C. gracilis, Schk., which he afterwards 
united with C. loliacea, L. It is certain that the species here de- 
scribed, as well as C. gracilis, Schk., is far removed from C. loli- 
acea, Li. It is so different from C. canescens, that it deserves the 
name above given, as Schkuhr cancelled the other.
