below the middle, more or less strong-ly hirsutulous, as are 

 also some of the petioles : sepals oblong-, obtuse, strongly and 

 closely ciliate with spreading^ or somewhat retrorse hairs : 

 corolla violet, large, about i^ inches wide, the petals nt)t 

 very dissimiliar, rather broadly obovate, the keel as broad as 

 the others and very obtuse. 



Described from specimens collected by Dr. Jas. Fletcher, 

 in open spaces among woods at Aylmer, Que. This species 

 has also been collected on Prince Edward Island, by Mr. L. 

 W. Watson and in Vermont. In general appearance V. sub- 

 viscosa resembles V. sepientrionalis but this latter species 

 " has a heavier foliage, of a light green shade, wholly devoid 

 of clamminess, each leaf with a broad open sinus and each 

 branch of its stout rootstock produces a considerable cluster of 

 leaves and flowers." 



Viola cardaminefolia, Greene, Pittonia, vol. iv, p. 289. 



Caulescent, the numerous slender decumbent or more 

 depressed stems 3 to 5 inches long : leaves small, the sub- 

 cordate-ovate obtuse minutely crenate blade often merely 

 y^ inch, seldom ^ inch long, of firm texture, obscurely pul- 

 verulent-puberulent, the slender petioles about i inch long; 

 stipules lanceolate, the lowest serrate-ciliate, the upper nearly 

 entire except toward the base : slender peduncles little more 

 than an inch long, bibracteolate much above the middle : 

 sepals subulate-lanceolate, glabrous : corolla small, deep-blue; 

 spur elongated, oblique. 



In rocky woodland near Aylmer, Quebec, Canada, 6 

 June, 1901, Dr. J. F"letcher. Allied to the common V. Muhlen- 

 bergiatia of the U. S. (now<rightly or wrongly called V Labra- 

 dorica), but easily distinct by its small, thick and somewhat 

 fleshy foliage always of ovate outline and obtuse ; the flowers 

 not half as large, much more deeply coloured, with a diff"erent 

 spur.
