 by many authors contain hetween them upwards of forty species, several 

 of which appear now to be considered as varieties ; the great majority of 

 these belong to the former genus, of which no less than twenty-one

 found in North America ; they are chiefly found in hilly or mountainous 

 districts ; there are two British species.
