Mr. Schweinitz on the Genus Viola- 77 



altogether with ours ; I am pretty sure it lias not hc^n ob- 

 served before ; at least not distinctly* In a very few lu- 

 stances hairs were scattered on the nerves of the underside 

 of young leaves ; otherwise the glabrosity is very constant. 

 It usually flowers before the leaves have fully expanded^; 

 middle of April and beginning of May is its time.

V. caulescens ; glabriuscula. Caw/^ simphci, summitate 

 tantum folioso, debili, saepe attenuate deorsum, erectiusculo, 

 glabro, subangulato aut tereti ; inlerdurn purpurascenti. 



Foliis alternis, lanceolato-hastatis, longe acuminatis, lobis 

 obtusis eroso-dentatis, in lanceolata parte, dentibus distant!- 

 bus ; nervis ex fundo emanentibuss in pagina superiori pilis 

 niinutis adspersis ; foliis ceterum glabris pagina inferiori, au- 

 tern glaucis et purpureo tinctis. Petlolis brevissimis. Sti- 



^i^//^- axillaribus minutis, ovato-acuminatis, ciliatis. 



-tioribus luteis, extus purpurascentibus, horlzontaliter in 

 pedunculis axijlarlbus, filiformibug, brevioribus foliis, stlpu- 

 lis alternis minutissimls. Pelalo infimo dilatato, subtrifido, 

 basi nigro striate, strils ramosis : Lateralibus, striis paucis; 

 barba parcissima : in superioribus rudimenta striarum. Co- 

 fycis laciniis liiieari-Ianceolatis, longiusculis, attenuatis^ sub- 

 dentatis. ^'ectenonon producto. 5//^/na/c truncate, lateribus 

 fasciculatim piloso. Capsidis glabris. Radice horizontali. 

 corallino-squamosa, bulbosa. 



A very handsomely distinguished kind, very common 

 here in May in shady places and among rotten wood on 

 steep hill sides. The stem is weak and therefore often in- 

 clining. The caulis very often enters deep into the loose 

 soil in which it grows before it expands into the root.' Gen- 

 erally five or six inches high. The leaves of almost all our 

 specimens, present a most perfect exemplification of an has- 

 tate leaf. I am therefore surprised, that Mr. Nuttall re- 

 marks, " tbey are rarely hastate.'' Possibly he is acquain- 

 ted with a variety in which this is the case- 



This species is more generally than any of the rest, af- 

 fected with the Aecidium Violae^ which frequently prevent^ 



\ 



I its developcment.
