222 BOTANICAL OBSERVATIONS 



In the rough variety I met with the following 

 diversities; * 



a. leaves as in No. b, of the smooth variety. 



b. as in No. c, of the same. 



c. as in No. d, of the same. 



d. root-leaves and lower caulifie leaves doubly 

 pinnate ; the last leaflets entire, the upper cauline 

 leaves simply pinnate ; leaflets linear, entire. 



e. all leaves doubly pinnate : the last leaflets 

 entire. 



f. leaves as in No. d, the last leaflets with distant 

 teeth. 



In both these varieties I found the flowers of a 

 blue, pale, violet, pale red, yellowish-white, and 

 white colour. 



47. Viola tricolor et arvensis. 



Linnteus made both plants varieties of the 

 same species, but other botanists, thinking them- 

 selves better informed, accused him of a 

 great error, and again dissolved this pretended 

 species composita into two, with the above names.
