lobo intermcdio oblongo, longiore et latiore, ceteris lineari *■ 

 oblongis, omnibus obtusis, ciliatis : pedunculis tetragonis. 

 foliis multo longioribus : calycis sepalis ovato-lanceolatis, 

 acuminatis, ciliatis, postice emarginatis ; petalis expansis, 

 albidis, raerulescenti tinctis, basi flavidis, superiore nudo 

 glabro, lateralibus barbatis, cumque superiore paucis lineis 

 cseruleis notatis; stigmate sub-pubescente, vix rostrato. 



V. bicolor, Pursh et Nuttall. V. arvensis, Elliott. 



Habitat a Nova Caesarea ad Georgiae submontosa. Plan- 

 tarn descripsi ut a me visam in collibus mpestribus Novas 

 Caesareae prope Noveboracopolin sponte crescentem : non 

 est Viola bicolor Europae, nee similitudinem cum Viola 

 arvensi (quae varietas V. tricoloris) habet. Claris. Schweinitz 

 refert, hanc plantam versus finem aestatis magna fit, sub hac 

 forma forte V. arvensis divi Muhlenberg est, in Catalogo 

 No. 20 adnumerata. Haec species cum V. rostrata sola omnium 

 Violarum Americanarum radicem fibrosam habet, omnibus 

 reliquis radix est squamosa. 



It now only remains for me to enumerate some obscure and 

 imperfectly known species ; and to give hints of some which 

 I have seen myself, but not particularly examined. This is 

 done in order to call the attention of botanists to a subject, 

 which my own wishes and the study of so many years have 

 rendered probably more important to rne, than it may be to 

 others : it is to be hoped, however, that it will not be without 

 its use in making more complete our knowledge of a most 

 difficult family of plants. 



The Viola debilis of Miehaux, is a very different species 

 from any described by me. I once found it in the mountains 

 of South Carolina, but failed in transporting it to a place 

 where it might be cultivated ; not having taken any notes of 

 it at the time, I am only enabled to state, that the leaves were 

 broad-ovate and cordate, the stipules lacerate and ciliate, and 

 the flower large and white; the stem decumbent. Elliott's
