70 Mr. Schweinitz on the Genus Viola. 



maximis, oblongo-lanceolatis, margine dentibus majusculis 

 distantibus quasi ciliatis. Petiolis canaliculatis glabris. 



Floribus maximis, ochroleucis, aut pallide sulphureis, 

 nutantibus in pedunculis longioribus foliis, filiformibus, 

 apice longissime stipulatis, stipulis linearibus acuminatis. 

 Fetalis magnis, limbo rotundatis, basi attenuatis. Binis la- 

 teralibus barba concolore profuse tectis, ceteris nudis; in- 

 fimo striis nigris picto. Cornu postice longiuscule produc- 

 to, obtuso. Calycis laciniis longissimis angustis, acumina- 

 tis, margine ciliato. Stigmate recurvo subpubesc. 



Capsulis glabris. Radice tenuiuscula. 



This is by far the largest flowered species of the family. 

 The stem rises in spreading tufts to a considerable height, 

 generally in a half bent way. It flowers in abundance be- 

 fore the leaves are fully expanded, and is highly remarka- 

 ble for the unusual ochre-color of its fine flowers. I have 

 met with it in borders of ponds and meadows in April and 

 along Dan river, towards the Saura mountains, attached to 

 rich soil. The next, is the only species with which it is 

 nearly allied — but can readily be distinguished by its size, 

 erect habit, and very differently shaped stipules. 



19. Species. V. repews Nobis. 



If observed by others, it has been comprehended among 

 the former in such a manner, as to render it impossible to 

 point out references. 



V. caulescens, decumbens, subrepens, stolonifera. Cau- 

 libus crassiusculis subangulosis, ramosis, foliosis, decumben- 

 tibus, minoribus quam in priori. Stolonibus longe lateque ir- 

 repentibus. Stipulis maximis, ovato-lanceolatis, margine ci- 

 liis longissimis viridibus densis exornatis, ex axillis foliorum, 

 cauli undique adpressis, fere ut in Violis stipulaceis euro- 

 paeis. 



Foliis inferioribus reniformibus, acutis, crenatis, glabri- 

 usculis, aut ut in priori : superioribus cordatis, subcuculla- 

 tis, dentato-serratis. Petiolis longiusculis, glabris, submar- 

 ginatis. Folia omnia minora quam in priori. 



Floribus minoribus ex luteo-albescentibus. Pctalo infi- 

 mo multo minori ceteris; lateralibus barba \onz,a alba. J^ec- 

 lario breviusculo. Calycis laciniis lanceolatis, multo latiori- 

 bus quam in priori, substriatis, acuminatis, ciliatis. Pedun- 

 ';ulis axillaribus breviusculis, in ipso apice longe stipulatii?v 



Capsula non observata. Radice ut in priori.
