Ludlowville, where both dlphylla and laciniata were not 

 found growing within a few meters of the same spot. 



If only the "typical" speoimens are considered, 

 there is considerahle variation in several respects, tho 

 Much less with the leaves than in the case of laciniata . 

 The rhizomes, in forms with typical leaves, may he only 

 slightly constricted (e. g., D. 8, Beechwoods), or moder- 

 ately constricted (D. 5, Beechwoods), or approaching the 

 type of laciniata (D. 61, opposite Beechwoods); the lat- 

 ter extreme is the form figured by B. & B. The specimens 

 collected would evidently make a pretty complete series 

 from the type of D* 8 to or nearly to that of laciniata , 

 and one of the doubtful forms described below shows typi- 

 cal dlphylla rhizomes. Further, while some specimens 

 are extremely mild in flavor, some are moderately pung- 

 ent. 



As to the leaves, forms described under dlphylla 

 and laciniata for Taughannock possibly represent some 

 of the"doubtful forms" referred to under maxima in C. F. 

 Among the typical specimens, while there is considerable 

 variation, no doubt this is very largely due, as with 

 dlphylla , to non-genet±o "fluctuation", the extremely 

 definite and varied leaf -forms of laciniata being absent
