80 JMr. Schwciniiz on the Genus Viola, 



calycem vis exccdentibus. Coniu nullo. Ccdycis laciniis 

 postice porrectis acutis, antice divergentibus laiiccolatis* 



Capsulis maximis oblongis glabris. 



The habit of this plant resembles the Triosteuin much 

 more than any of our Violae. The stem is from one to 

 two feet high, rather bending. 



I conchide with a Synoptic (able of all our Violac in or- 

 der to facilitate their examination. Traces of a few oth- 

 ers not gufficientlj examined lead me to believe, that there 

 »re still a number of :-pecies in America undescribed,
