villous involucral scales, and its broader and shorter li- 
gules. ;

* No. 502 in my set. I have the same species amongst a set of 
Composite, which would induce a belief that it is the same as C. art 
Less., a plant very vaguely described in the Linnæa, v. 6, p. 138; but 
is certainly very unlike the C. friplinervia, Less., nor does it at all a 
with De Candolle's character of C. arguta.—G. B.
