Var. Walteri (the C. Walteri, Pursh., C. cylindrica, var.. 
Walteri, Torr. and Gray, &c.) is a very narrow-leaved form 
of this sort, and doubtless includes even the 0. linearilota,. 
D.C., figured by Delessert from a dried specimen with flower 
unnaturally outspread.— A. Gray, Herbarium, Kew, October 
25th, 1881.
