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 production of 
three leaflets from one point; whence also Trefoil in English, Tréfle in 
French.
