 Diagnosis: 



See under "Variation"; also, under "JQHagnosis" 

 for D« diphylla . Tubers rarely shallow, often difficult 

 to dig up because of depth. Radical leaves rather uncom- 

 mon. 

 Variation . 



Before the widely aberrant forms are considered, 

 the variation of the forms more or less truly "typical" 

 must be considered; and it is astounding. A really 

 adequate description of the multitudinous leaf -forms 

 observed is Impracticable here, and in fact a really 

 good idea of it can hardly be conveyed readily to one who 

 does not examine the plants themselves. Aside from gen- 

 eral size -differences that are presumably in part genetic, 

 the plants differ In position of leaves, length of pet- 

 ioles, width of leaflets, and length of leaflets, and 

 In depth, frequency, and form of serration and incision 

 of leaflets, the forms resulting are simply multitudin-
