1765. E. scoparia L. (Malpighia, Genova, iv, 1890.) Delpino describes this 

 species, native to South Europe, Dalmatia and France, as anemophilous. 



1766. E. arborea L. (Knuth, 'Blutenbiol. Beob. a. d. Ins. Capri,' p. 11.) 

 I have not seen fruits set by this species in Capri. In April the sticky stigmas still 

 projected from the flowers, though the anthers had all shed their pollen.
