I. VIOLA. 33 



I find this, and a plurality of other species, indicated 

 by Linnaeus as having triangular stalks, " caule triquetro," 

 meaning, I suppose, the kind sketched in Figure 1 above. 



39. Til. TIOLA AKVEXSIS. Field Tiolet. Flora Dan- 

 ica, 1748. A coarse running weed; nearly like Tiola 

 Cornuta, but feebly lilac and yellow in colour. In dry 

 fields, and with corn. 



Flora Suecica, 791 ; under titles of Tiola 'tricolor' 

 and 'bicolor arvensis,' and Herba Trinitatis. Habitat 

 ubique in sterilibus arvis : " Planta vix datur in qua 

 evidentius perspicitur generationis opus, quam in hujus 

 cavo apertoque stigmate." 



It is quite undeterminable, among present botanical 

 instructors, how far this plant is only a rampant and 

 over-indulged condition of the true pansy (Tiola Psyche) ; 

 but my own scholars are to remember that the true 

 pansy is full purple and blue with golden centre ; and 

 that the disorderly field varieties of it, if indeed not 

 scientifically distinguishable, are entirely separate Iroin 

 the wild flower by their scattered form and faded or 

 altered colour. I follow the Flora Danica in giving 

 them as a distinct species. 



40. Till. TIOLA PALUSTEIS. Marsh Tiolet. Flora 

 Danica, 83. As there drawn, the most finished and deli- 

 eate in form of all the violet tribe ; warm white, streaked 

 with red ; and as pure in outline as an oxalis, both in 

 flower and leaf : it is like a violet imitating oxalis and 

 anagallis.
