Also represented from Mexico without locality by a specimen 
in Herb. Pavon (Mus. Brit.), which was cited by De Candolle. 
Palmer’s No. 176 (Herb. Kew. et Mus. Brit.) from Guaymas, 
Sonora, has very coarsely serrate leaf-segments approximating 
in shape to those of A. Wrightii. Rose’s No. 1624 from between 
Rosario and Colomas, Sinaloa, has equally coarse serration, and 
the mesophyll is conspicuously marked on the lower surface 
with irregular brown dots and dashes due to the presence of 
resin. These two numbers were distributed as A. palmatifida, 
but the identification will remain in doubt until seeds are known.
