I have separated this genus from HelicJirysumy on ac- 
count of the peculiar structure of its involucrum, whose 
scales are nearly of equal length, and terminated by a long 
twisted point, to which the generic name alludes. The spe- 
cies agree so well in habit and character, that, although 
perfectly distinct, they are with difficulty characterised, so 
as to be easily known. The generic name is composed of 
frmigcty spira^ and Ag^r;?, squama.
