There are few rare species of plants the geographical 

 range of which is much greater than this. It was originally 

 found in Corsica by M. Robert ; it has since been dis- 

 covered in Italy, near Pisa and Naples ; it is common in 

 the meadows of Tauria and Caucasus, and in fields on the 

 borders of the Volga, near its mouths ; and finally, it inhabits 

 a few places in Hungary. 



We have carefully compared it with the cultivated 

 Pisan plant, in the Garden of the Horticultural Society, 



* This name has obviously been suggested by the uniform ])roduction of 

 three leaflets from one point; whence also Trefoil in English, Trijlc in 

 French.
