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, L.. It is so different from C. canescens, that it deserves the 
name above given, as Schkuhr cancelled the other.
