not seem to be sufficiently correlated with other structural peculiarities or 
geographical factors. 
3. E. borumensis, Hack, in Bull. Herb. Boiss. 2 me ser. i. 765. 
Perennial, up to over 3 ft. high, with a short stout rhizome emitting 
very stout roots and innovations which are intravaginal or at least
