Mr. Schweinitz on the Genus Viola. 67 



Remarks. — The caulescent Violae of America appear to me 

 to have been less accurately observed than the former family, 

 although I think they are rather easier to be distinguished* 

 A good number have been rather incautiously referred to 

 such from whom they manifestly differ. 1 find it impossible 

 to unravel the species generally received, without establish- 

 ing some new ones ; although I am persuaded that speci- 

 mens of most of these, have been under the eyes of other 

 Botanists, without being sufficiently distinguished. The at- 

 tention which I have bestowed upon such, as grow in our 

 vicinity (including the greater number) has, 1 hope enabled 

 me to discriminate properly. The V. striata and V. debi- 

 lis of authors appear to have been particularly loosely ob- 

 served, and form an aggregate of very distinct species, ren- 

 dering it altogether impossible to say which is meant in ev- 

 ery instance. The V. ochroleuca ', \ . repens ; V. debilis ^ 

 and V. uliginosa attempted to be here correctly establish- 

 ed, have, 1 have reason to presume, been comprehended 

 hitherto under one or the other of the above two names. 

 My V. striata is altogether a different species from these, 

 and has probably not been before observed. Jt was first 

 pointed out to me in our vicinity, by Mr. John Leconte, 

 who was of opinion that it had been no where described. 

 I call it striata with him, because that name certainly be- 

 longs more appropriately to this Viola, than to any of those 

 to which it has before been applied. The striata of au- 

 thors comprizes as I judge, my two species V. ochroleuca 

 and V. repens. (I should have named the latter decumbens 

 if there was not already a species of that name indigenous 

 to the Cape of Good-Hope.) My striata approaches nearer 

 to V. pubescens and eriophora than to the above. 



With regard to the caulescent Violae in general it may 

 be observed that they appear later in the season than the 

 former family ; and have a marked predeliction for the yel- 

 lowish color in their flowers. 



Besides the alterations above recited, I have ventured to 

 propose a new species in a very handsome little Viola from 

 Labrador, with which I begin, as it is apparently the least 

 caulescent of the family.

Perhaps somewhat related to V. unijlora. Pers. n. 28. 

 of Liberia, from which it differs however by Willdenow's re«
