Mr. Schweinitz on the Genus Viola. 55 



purpureo-striato; in cavitate pistillacea, barba rara alba ob~ 

 sito. Binis laterallbus, intus ex albidis, striatis, barba rigi- 

 da alba parte superior! adnata. Binis siiperioribus, nee 

 Striatis nee barbatis. Calycis laciniis ovato-lanceolatis, gla- 

 bris, venosis, brevioribus, margine ciliatis. Stigmate clava- 

 to-capitato, recurvo, nee depresso, nee nfiarginato. 



Scapis filiformibus, foliis brevioribus, glabriusculis aut 

 pilis raris. Stipulis binis alternis minutis lanceolatis, infra 

 medium sitis. 



Capsulis glabris, minoribus. 



Rad'ice crassissima, eorrallina, obliqua, emittente fibros 

 longos et caespitibus foliosissimis densis tecta. 



I have more frequently found this species, without any 

 lobed leaves at all, than with them, both during inflores- 

 cence and afterwards ; and it is then that it would resemble 

 cucullata so much, were it not for the constant pubescence, 

 which, in the petioles, is always apparent, even when it 

 nearly disappears in the leaves and scapes. Indeed, the 

 lobed or palmate interior leaves are always scattered only, 

 and the great majority cordate, cucullate or reniform, grow- 

 ing in very dense and large tufts. All have a tendency to 

 run down into the petiole, though not equally striking in all 

 specimens. The whole habit is very different from palmar 

 ta ; and as I have studied it in many specimens for several 

 years, I can aver with confidence, that no degeneration of 

 the one into the other takes place. I find this species 

 chiefly on cultivated grassy, steep hill sides and on meadow 

 margins. It begins to flower early in April and continues 

 into May. Not unfrequently tufts are met with of more 

 than one foot diameter. The oblique scaly root then often 

 exceeds an inch in thickness. This species is very often 

 found with flowers remarkably variegated, with white blotch- 

 es, in an irregular way. As observed, the constant pubes- 

 cence distinguishes it from cucullata : to point out the 

 main characteristics that separate it from palmata I thus 

 contrast them : 



V. palmala. V. asarifolia. 



FoL. raris integris ; i>\ar. palmat. null. = raris palmaLplavim, cordafo-cucul- 



cucull. latis 



Petiol. tenuioribus interd. glabris. = semiteretibus validis semper pilosis^ 

 Stipul. radic. lanceolatis integris. = saepe divisis, multo longioribus, 

 Scapis longitudine foliorum. = brevioribus foiiis 



Petalo infimo omnino glabro. = barba rara obsito. 

 Stigmate depresso marginato, = globoso-imnjarginato.
