10. FRANKENIACE^. 187 



Descends to the coast level, in the Channel. 



Ascends, on the coast level, to the Ouse. 



Range of mean annual temperatui"e 51 — 49. 



Native. Littoral. Cuiiously confined to the south-east- 

 .t ero.angle of England; being reported from the counties 

 of Hants, Sussex, Kent, Essex, Suffolk, Norfolk, Cam- 

 bridge and Durham. The locality in the county of Dur- 

 ham being only that of " ballast hills," and ap]3arently not 

 verified of late years, may be thrown out of the true area. 

 I cannot say whether still found in Cambridgeshire ; but 

 the letter " c," affixed to the name in Henslow's Catalogue, 

 implies that the plant was there at no very distant date. 

 Why does this species not extend westward of Hampshire ? 



Frankenia pulverulenta, Linn.

Incognit. It is difficult to say whether this belongs to 

 the veiy small gi-oup of extinct species, or to the numerous 

 assemblage of those the names of which have been impro- 

 perly introduced into English lists, through mistakes as to 

 the species observed. Ray omits it, but it was added to 

 the third edition of Ray's Synopsis, by Diltenius, who says, 

 " found on the coast of Sussex, and sent by Mr. Brewer." 

 To this authority Hudson added his own, by the words, 

 " In littore Sussexiaj inter Bognor et Brighthelmstone in- 

 veni." Nobody has since found it, and we make certain 

 that it would not have escaped Mr. Borrer's eyes, if stiU 

 existent on the coast between Bognor and Brighton.
