This genus is so nearly allied to Hippophae, as well as to 
another which Iam about to propose, that it is to be re- 
gretted any artificial system should ever separate them. 
They are, however, distinetly dioicous, So pred male = ; 
_ female flowers of different structure. Of this genus, be- — 
_ siden the above, (which appears to be ecm Fe ger 
to the E. macrophylla of Japan, than the E. latifolia), there 
are 10 species; 1 in the South of Europe, another in Rus- 
sia and the East, another in Egypt, and a 4th in Ceylon, 
with 6 in Japan.
