54 Mr. Schweinitz on the Genus Viola. 



that in all varieties and at all times there are but few and 

 scattered entire leaves, and the great majority pahnately 

 lobed in some shape or other; while the contrary is the 

 case in the next. Besides this never forms dense tufts, and 

 frequently no tufts at all. It is only high in an advanced 

 state — in early spring it is very low. It is in flower here 

 from March to May. After inflorescence, the leaves gen- 

 erally grow to a considerable size. No variety of this spe- 

 cies, that has fallen under my observation, is found in 

 swamps or bogs. With this exception, they occur in great 

 quantities almost every where.

 that it is in certain cases distinguishable from V. cucullataj. 

 only by the constancy of the pubescence; which' applies to. 

 this species exclusively, as all varieties o( palmata, at all 

 times, are provided with palmately lobed leaves. Some of 

 Mr. Elliott's observations on palmata seem to indicate, that 

 he had specimens of asarifolia among his. The asarifolia 

 of Muhlenberg's catalogue, is a very different plant of the 

 caulescent familyyas Mr. Elliott observes correctly,
