44 CORRESPONDENCE OP RAY. 



sive fraxinus sylv., Park. [Pyrus aucuparia, 

 Gaertn.],is common also hereabouts, though inaptly so 

 called. 



Erica baccifera nigra, Park. \_Empetrum nigrum, 

 Linn.], I have also, with you, observed plentifully on all 

 the moors. It grows also on a heath within a mile of 

 this place. 



The other two sorts of Erica you mention are frequent 

 on all the heaths of England. 



Scorodonia \_Teucrium Scorodonia, Linn.] also is a 

 plant most common in the woods in almost all parts of 

 England, excepting Cambridgeshire. 



Sonckus Icevis alter parvis Jtoribus [Lactuca muralis, 

 De Cand.] is no rare one ; and two years since I found 

 it within a mile of Cambridge. 



Hieracium rectum rigidum, quibusdam sabaudum, J. B., 

 et Hieracium fruticosum- angustifolium majus, Park. [Hie- 

 racium umbellatum, Linn.], I do not distinguish, but 

 make the same, and therefore desire you to tell wherein 

 you put the difference. The plant I have observed in 

 many sandy and some rocky grounds. 



Your Thlaspi fruticosum leucoii an globular ia folio la- 

 tissimo is, for aught I know, a nondescript. I desire, if 

 you have any of it dried, to send me a branch. I look 

 upon it as a great discovery, if it be not Camelina Ger. 



Pyrola vulgaris nostras [P. rotundifolia, Linn.] I have 

 found in many places in the north. 



I am much to seek what your Lcucoium, or Hesperis, 

 with a very broad leaf, should be, unless perchance 

 'BursaR pasloris locido oblongo qffinis pulchra planta, J. B. 

 \_Draba muralis, Linn.], which I have found in Craven. 



Lychnis sylvestris flore purpureo \Lyclmis diurna, 

 Sibth.] is a plant everywhere very common, and doubt- 

 less may be found in Cambridgeshire, though omitted in 

 the catalogue. 



The Knoutberry I have found on all those hills you 

 mention, but with the fruit only on Hinckell-hoe. 



Raspberry is also frequent on the mountains both in 

 Wales and in the north.
