A. conchifolia is of about the same size as A. clypeata, and 
agrees with it in the position of its female flowers. It differs in its 
obliquely spreading, convex lobes with revolute apex and margin, 
in its oblong lobule with acuminate apex and in its imbricated un- 
derleaves, usually broader than long. From 4. Sellowiana it dif- 
fers mainly in its smaller size and in the characters of its convex 
leaf-lobes, which are not at all falcate. 
A. conchifolia is perhaps closer to A. xanthocarpa than is the 
preceding species, agreeing with it in its convex leaf-lobes with 
revolute postical margins. It is, however, much less robust, its 
lobes spread more obliquely, its lobules are relatively larger and 
their apices can usually be made out without dissection.

Notes that thé name ‘‘ versicolor,’ although finally restricted by the authors of the 
ata." According to the strict rules of priority, 
replace the name **repleta" of Taylor, but apparently there is enough reason for 
giving it up altogether. Of course the name ۴ teretiuscula’’ has no claims whatever.
