54. OROBANCHACEiE. 225 



Agrarian region. Inferagrarian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 51 — 47. 



Native. Sylvestral, Ericetal. Parasitical upon Ulex, 

 Spartiura, &c. Much confusion prevails among the pub- 

 lished localities for our various species of Orobanche, 

 which renders the indication of their geographical rela- 

 tions highly uncertain and unsatisfactory. The East and 

 West Highland provinces are excluded from the true area, 

 under the presumption that the habitats published for " O. 

 major," on the coasts of those provinces, really belonged 

 to O. rubra. Babington has adopted the name of " O. 

 rapum (Thuill.)" for this species, and cites Fries as his au- 

 thority for O. major (Linn.) and O. elatior (Sutt.) being 

 synonymous.
