Mr. Schweinits on the Genus Viola. 79 



this is nearly hid by the very large pihnatifid stipules- In 

 time it grows very high, and but few of the radical leaves 

 remain. The first flowers are larger in proportion than 

 the later ones, and on short peduncles. 



V. caulescens, glabriuscula. Caule triquetro, anguloso, 

 erecto, simplicinsculo, fohoso. 



Foliis radicalibus, rotundato-spathulatis glabris, subden- 

 ticulatis : superioribus et secundariis lanceolato-spathula- 

 tis aut ovatis, brevitcr petiolatis. Stipulis oppositis, in me- 

 dio et summo caule maximis, cristato-palmato-pinnatifidis, 

 lobis multis, medio lobo longiori, ceteris lineari-oblongis 

 obtusiusculis — in parte inferior! caulis stipuhs muioribus. 

 Omnibus margine ciliatis. 



Fiorihus minoribus ex albo-coerulescentibus, in peduncu- 

 lis longis angulosis sulcatis, glaberrimis axiliaribus. Peta- 

 lo infimo basi lalescenti,non barbate, venissimplicibus, pau- 

 cis, coeruleis. Lateralibus exalbido-coeruleis,barba rigida 

 alba. Superioribus nudis. Nectario parum postice por- 

 recto. Calycis laciniis postice rotundato-auriculatis, cilia- 

 tis, antice lanceoiatis. Stylo brevi. Stigmate clavato-tur- 

 binato, foramine urceolato, subpubescente. Capsulis ova- 

 lo-giobosis, glaberrimis, albis. Radice filiformi longa. 



C Viola Anomala. 



The only remaining species is altogether so different In 

 habit from the rest, that it assuiedly ought to form a dis- 

 tinct Genus, to which probably some of the tropical ones 

 belong. It does not grow in our vicinity ; although it may 

 be found in our mountains, as Mr. Elliott states. Mr. 

 Nuttall has observed it in Upper Louisiana. My speci- 

 mens are from Bethlehem, Pennsylvania.
