4. Tall Broomrape. Orobanche elatior, Sutt. (Fig. 714.) 

 (Eng. Bot. t. 568.) 



Closely resembling the greater JB. in 

 stature and flowers, of which, it is pro-

 corolla are less unequal and more toothed,

 abundant than the greater B. in eastern 

 Europe, but rare in England. Fl. 

 summer.

 exceed a foot ; the lower flowers of the 

 spike are at some distance from each 

 other. Segments of the calyx ending 

 in long, slender points. Tube of the
