 uniform in their character, and remarkable for the pyramidal (rather than deltoid) 

 form, broad at the base and gradually narrowing to the apex: the lower pinna; 

 are invariably pinnatifid.

 (var. 7). — Dr. Wallich's specimens appear to constitute a good species, yet too 

 near A. sylvaticum. I am disposed to consider the two vars. noticed above to 

 be forms of the same.
