Mr. Schweinitz on the Genus Viola. 71 



This is of a much smaller size than the former and well 

 distinguished by its decumbent, spreading and even creep- 

 ing growth, smaller flowers and their white beard, but no 

 less, by the broad and strongly fringed opposite stipules, 

 which at first might be taken for pinnatifid ones, and the 

 very small lower petal. It has been found here exclusive- 

 ly on the rocks of the Saura mountains, where it forms con- 

 siderable patches. It flowers in May. I contrast the two 

 Species thus : 



V. ochroleicca. V. repens. 



Caplibus assurgentibus, erectis, = decumbentibus, atoloaiferis minori- 



majoribus bus. 



FoLiis cordatis, obtusis ac acu- =■ reniformibus et cordatis, minori- 



minatis bus. 



Floribus maximis ; barba concolore =' tninoribus ; barba alba. 

 Petalo infimo magno, rotundato = minutissimo, aequali. 

 Slipulis axillaribus margine denti- =t margine longissime denseque cilia- 

 bus distantibus dentatis, maxim- tis, magnis ovatis, caule adpres- 

 is, oblongis sis.

I have some suspicion that Elliott's specimens collected 

 by Dr. Macbride may belong to the uliginosa of Muhlen- 

 berg, called asarifolia in his catalogue. The rest of the 

 synonymy I believe is correct. 



V. caulescens, glaberrima, decumbens et erecta. Cau- 

 lihus caespitose ex radicibus provenientibus, foliosis, bre- 

 vibus. 



Foliis reniformi-cordatis, obtusiusculis, basi saepe cucul- 

 latis, saepe suborbiculatis, crenatis, utrinque glaberrimis, e 

 sinu quasi in petiolos subdecurrentibus ; minoribus. Peti- 

 olis diff"usis longiusculis. Stipulis axillaribus lato-lanceola- 

 tis subdivisis, ad basin tantum serrato-ciliatis. 



Floribus palHde coeruleis, nutantibus in pedunculis medio 

 stipulatis, longiusculis, axillaribus, folia excedentibus. Pe- 

 talis omnibus limbo rotundatis, binis lateralibus parce bar- 

 batis ; infimo venoso. Nectario longo, postice valde por- 

 recto, attenuato. Calycis laciniis linearibus, angustis, gla- 

 bris, albo-marginatis, postice truncatis. Stigmate tubulos- 

 so, rostrato, papilloso. 



Radice obliqua, longiuscula, radiculosa. Capsida non 

 observata.
