Tue diagnoses and descriptions following are those of species 
and varieties discovered by the author in Syria and the adjacent 
regions of Asia Minor. All references to species and other 
botanical subdivisions are to the ‘Flora Orientalis’ of Boissier. 
The plants described have been carefully compared with the 
nearest allied species in the Herbaria of M. Boissier at Geneva, 
and of the Royal Gardens at Kew, to the authorities of both 
of which establishments the author is indebted for much aid, 
which he desires gratefully to acknowledge. For convenience of 
reference, the varieties have been put in the order of the species.
