THE PASTURE-THISTLES, EAST AND WEST. 
E. J. Hur. 
IN the summer of 1909 I had an opportunity to examine for the 
first time in the field the eastern pasture thistle, Cirsium pumilum 
(Nutt.) Spreng., and to compare it with its nearest western relative, 
C. Hillii (Canby) Fernald, the only one of the two species which I 
have as yet seen in the vicinity of Chicago. "The plants of C. pumi- 
lum were growing quite abundantly on a gravelly hillside pasture that 
sloped down to French Creek, just below the village of Saegertown, 
in northwestern Pennsylvania. The time of finding, Aug. 31st, being 
! Var. calvescens may occur in northwestern America but the material at hand is 
inadequate for deflnite determination of that point, and, as already indicated by 
Gray (Bot. Cal.), Rehder, and others, seems to differ in some regards from the eastern 
varieties. -
