DIDYNAMIA. 



y. Springy places in the Grampian mountains, G. Don. Fl. May, 

 June. ^ . 



Plant varying extremely in size and direction. Sometimes 1 ]i 

 foot high,, and quite erect. Lower leaves on long footstalks, ex- 

 tremely variable in their shape and in the depth and distinctness of 

 the crenatures. I apprehend the vars. /3.-and y. may chiefly be at- 

 tributed to a colder climate or poorer soil. The flowers are large, 

 several from a stalk in a., almost solitary in the p. and y.
