The specimens collected by Mr. P. W. Mackinnon in Dehra Dun 
at about 3,000 ft. differ very considerably from the typical A. 
tortuosum of Schott, which is found abundantly on the Simla Hills 
at a much higher-elevation. The tubers of the Dehra Dun plant 
are usually much smaller, and the leaflets are very different, and 
much more like those of A. helliborifolium as depicted on p. 541
