This species, S. Small, and the following, S. pauperculus, 
are, as a rule, easily distinguished by the taller stems, longer 
leaves, more numerous and somewhat smaller heads of the 
former; but in southeastern Pennsylvania and in Maryland 
oceasional forms occur, for example, Crawford's specimen 
from Tullytown, 15 May, 1896, and Small’s specimen from Mt. 
Hope, 24 June, 1901, which are somewhat intermediate. 
These two specimens seem to the writer to possess rather 
more the characters of S. Small than of S. pauperculus. 
Moreover, Crawford's specimen from Westtown, Pa., 22 June, 
1895, is a perfect match for Heller's specimen, No. 10263,
