Viola enocarpa Schwem. 



out the state. It is more frequent and abundant in beech and sugar maple 

 and white oak woods. 



Most of our specimens are more pubescent than the typical form, in 

 fact many so closely approach Viola pubescens in pubescence that it seems 

 wrong to place them with this species. 



Conn., s. Ont. to Minn., southw. to Md. and Okla. 



16a. Viola eriocarpa Schwein. forma leiocarpa (Fern. & Wieg.) Deam, 

 comb. nov. (Viola eriocarpa var. leiocarpa Fern. & Wieg. in Rhodora 23: 

 275. 1921.) This is a form with glabrous capsules. In my Indiana fruiting 

 specimens I have 19 sheets with woolly capsules and 28 sheets with 

 glabrous capsules. The forms have no specific geographical range in 

 Indiana. 



17. Viola pubescens Ait. Stemmed Downy Yellow Violet. Map 

 1449. In rich, moist woods. Rare. 



N. S. to N. Dak., southw. especially in the mts. to Va. and Mo. 



The separation of this species from the preceding is not at all satis- 

 factory. The characters used in their separation are not constant and it 

 appears from my specimens that all characters fail about equally, so that 

 a preponderant character is absent. If it is true that this species has no 

 long root leaves and never branches at the base, then I have only 3 speci- 

 mens of it from Indiana. But we have specimens that are much branched 

 that are as pubescent as any we have. It is likewise with other characters, 

 such as width of the stipules and the number of the teeth of the leaf 

 margin. 



17a. Viola pubescens var. Peckii House. (N. Y. State Mus. Bull. 243- 

 244: 50. 1923.) The form with glabrous capsules. I have it from Steuben 

 County. 



18. Viola canadensis L. Canada Violet. Map 1450. Almost invariably 

 found in beech and sugar maple woods and rarely in white ash and red
