Mr. Schweinitz on the Oenus Viola. 1 1 



This is of a much smaller size than the former tind weJl 

 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. Qchroleuca. V. repens- 



Caulibus a33urgentibu3, erectis, = decuinb€ntibus, sloloniferis minori- 

 majoribus bus, 



FouLis cordatjg, obtusia ac acu- = reniformibu^ et cordatis, minori-

Fhribus maslinia ; barba coacolore =■ minoribus ; barba alba.

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 

 synonyn^y i believe is correct.
