 SEEDS numerous and roundifh. 



IT is in Bogs only that we find the Viola paluflris, the leaft fhowy of all our Englifh Violets, and in fuch 

 fituations it generally abounds, on the boggy part of Shirley Common near Croydon, it may be found in flower in 

 April and May. 



It is diftinguifhed from the other fpecies by the peculiarity of its place of growth, the greater roundnefs of its 

 leaves, the palenefs of its flowers, and the extraordinary form of its ftigma, vid. pi. fig. 6. In its ceconomy it 

 refembles the Viola odorata, hirta, &c. producing ripe feeds without perfect bloftoms, and that in a greater 

 quantify and for a longer continuance than any of the others. 



A Violet with red ftriped bloftoms is mentioned by Parkinson, under the name of Viola ruh ajlrlata Ebora- 

 cenfis which is confidered by Mr. Ray and later writers, as only a variety of the prefent planet.
