Mr. Scliweiiiitz on the Genus Vioia. 57 



5. Species. V. triloba. Nobis. 



With some diffidence I venture to propose this new spe- 

 cies, notwithstanding its striking characters, because I have 

 found it but rarely. I have however met with it twice or 

 thrice in different years, and in different places — videhcet 

 rich woodland and meadows — constantly under the form 

 here described. At all events it deserves to be pointed out 

 for further observation. 



V, aeaulis. Foliis biformibus ; alteris exterioribus iato- 

 reniformibus, margine grosse crenato-dentatis, sinu recti- 

 lineo integro ; alteris interioribus trilobis. Lobo medio 

 ovato, grosse dentato, acutiusculo. Lobis binis lateralibus, 

 aequahbus, subbidivlsis, basi rotundatis, hastatim expansis, 

 margine dentatis. Nervis prominentibus in omnibus. Fo- 

 liis ceterum glabriusculis aut raris pilis obsitis, colore lute- 

 scenti-viridi. Petiolis marginatis, glabriusculis, longiuscu- 

 lis, praesertim in foliis trilobatis. Stipulis radicalibus bre- 

 viuscuhs, lanceolatis, giabris. 



Floribus coeruleis, eleganter venosis, subnutantibus. Fe- 

 talis ovatis purpureo-striatis, albo-barbatis, barba longius- 

 cula. Jfectario minori. Superioribus et lateralibus basi 

 attenuatis. Calycis laciniis giabris, lato ovatis, marginatis. 



Stigmate recurvo, marginato, depresso. 



Scapis brevioribus foliis, angulatis giabris. Stijjulis min- 

 utis distantibus. 



Capsula ignota. Radice crassa, undique radiculosa. 



The whole plant has a glabrous habit, although the leaves 

 are sparingly beset with short hair : they are of a remarka- 

 ble yellowish green color and spread considerably, although 

 but few in number with but few flowers in the tuft. I 

 have found this Viola only late in spring. It approaches 

 nearest to some varieties of palmata from which, however, 

 its whole habit appears to separate it. 



Remark. — The foregoing are all the species of heterophyl- 

 lous Violae acaules, I have observed, or been able to re- 

 gard as distinct species. Mr. Elliott's var. d. heterophylla oi 

 palmata, with which I am unacquainted, almost appears to be 

 a distinct species, among the rest, on account of its growth 

 in swamps — where I have never met with any of the recited 

 species. I could however not presume to decide on a plant 

 entirely unknown to me.
