Between Rosario and is Rose 1624; Culiacan, 
Brandegee. Rose’s specimen differs from typical A. palma- 
tifida in the less deeply divided leaves, which have broader 
segments with a shorter basal portion. The serration is 
coarser, and the mesophyll is conspicuously marked on 
the lower surface with irregular dots and dashes due to 
the presence of resin. I have not seen Brandegee’s 
specimen.
