356 ADDITIONAL SPECIES, ETC. 



North limit in Fife, ? 



Estimate of provinces 10. Estimate of counties 30. 



Latitude 50 — 56. Englisli type of distribution. 



Agrarian region. Inferagrarian — Midagrariau zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 52 — 47. 



Colonist. Agrestal. Ascertained in 15 counties ; and 

 it may be expected in at least double that number, consi- 

 dering the great probability of its being overlooked through 

 its close resemblance to F. dentata, and the recent j)eriod 

 at which attention has been particularly drawn to it. I 

 can scarce yet persuade myself of its permanent distinc- 

 tiveness from F. dentata; but I have frequently looked 

 without success for their two kinds of fruit on one single 

 plant. (See vol. ii. page 28.) 



538. Fedia eriocarpa, Desv. 



Area [7]. 



Incognit. The true F. eriocarpa appears sufficiently 

 distinct from F. dentata ; but I do not suppose that it has 

 ever been found in Britain. Several of the Fedias, and 

 perhaps more especially F. dentata, vary very much in the 

 size and form of the calyx crowning the fruit ; and hence 

 probably a form of F. dentata, with an elarged calyx, has 

 been mistaken for F. eriocarpa. Indeed, an able conti- 

 nental botanist, who lately visited England, told me that 

 he had found F. eriocarpa in Sussex ; but on my request- 

 ing to see his specimens, they proved to be the large-caljTc 

 form of F. dentata. (See vol. ii. page 28.)
