Flowers in May—grows in marshes. Penn.—Muh. 
The description of this species is derived from Willd., 
Muh., and Schk., as I suppose the plant has never come un- 
der my observation. ‘The species, no. 49, by 
Schw. and Torrey, and supposed to be the C: digitalis, 
Willd. (for the Herbarium of Muh. seems not to contain the 
plant), is acknowledged to be the C. gracillima, Schw. de- 
scribed in this Journal, V p- 98. 
p- and their 
tion does not at all agree with that of Muh. or Willd. - Until 
the two plants are proved to be identical, by an actual com- 
parison of specimens, the following characters will be ieee 
sufficient for considering them different species. The name 
of C. digitalis implies that it is short, and Willd. states it to 
be * in altitudine digitalis,” a finger in height, or about four 
inches ; C. gracillima is from one to two feet in height, and 
often is more than three feet in height :—the former has radi- 
cal glaucous leaves ; the latter has not, and the colour of its 
leaves is light or yellowish green :—the fruit of the former is
