title of Robert's Icones ; but this work has never been made 

 public, only a few copies having been occafionally diftributed 

 in prefents by the French government. To the older Botanifts 

 it appears to have been but very little known, from the time 

 of Tournefort, who firft mentions it. Ray appears to 

 have had only a fmall fpecimen from Dr. Charles Preston, 

 and even Haller had never feen it, in a living ftate, when 

 he wrote his Hijloria Stirpium Helvetia, 



Befides the length of the fpur, which equals the petals, there 

 is another character that might have given rife to the name of 

 cornuta, or horned, but as it does not appear to have been 

 noticed,^ it is moft probable that this name was applied on ac- 

 count of the length of the fpur or nectarium only. We allude 

 to the remarkable length of the fegments of the calyx which 

 appear between the petals fomewhat like a pair of cow's horns, 

 particularly the two lowermoft fegments, which are bent a 

 little upwards, that is with refpect to the obferver, for with 

 refpect to the flower they point downwards, this being refupinate 

 or inverted ; a circumftance very neceflary to be attended to 

 in reading the defcriptions of moft of the violets, otherwife 

 the young Botanift is apt to be puzzled by finding what is 

 defcribed as the uppermoft petal to appear to him to be the 

 lowermoft. 



Our drawing was taken at the Botanic Garden, Brompton, 

 of which this plant has long been an inhabitant.
