434 ADDITIONAL NOTES, ETC. 



359. Mespilus germanica, vol, i. p. 364. 



Mr. Pascoe marks this as a species that has been re- 

 ported to occur in Cornwall ; and by the Rev. W. H. 

 Coleman it is marked as having been seen by himself, in- 

 digenous within five miles of Dunster, Somerset. It may 

 perhaps be held indigenous or denizen in provinces 1, 3, 

 3 ; introduced or uncertain in 5 and 9. My individual 

 opinion, however, would incline to place it in the category 

 of alien species in Britain. 



360. Cratcegus Oxyacantha, vol. i. p. 364. 



Province (18) should be enclosed ; for, whatever view 

 may be maintained about the other provinces, there 

 would seem to be no sufiicient ground for supposing this 

 species a true native in the North Isles. By a misprint 

 or mis-transcription in volume first, province 18 was not 

 enclosed in the line of area ; although the substitution of 

 all the Nos. in detail, in place of the word " general," in 

 connexion with the remarks of the text, would show that 

 it was intended not to reckon the North Isles in the true 

 area. The variety " eriocarpa " may be usually recog- 

 nized by its less robust growth and more deeply cut 

 leaves ; but I cannot trace any constant difference suffi- 

 cient for specific diagnosis. 



361. ' Cotoneaster vulgaris, vol. i. p. 365. 



Mr. Edwin Lees says that the altitude of its station 

 "may be between 400 and 500 feet high." Thus, 150 

 yards may be indicated both for the upper and the lower 

 limit, at the one solitary station, yet clearly ascertained 

 for this shrub. 



362. Pyrus communis, vol. i. p. 366. 



Provinces (9, 12) may be added in the enclosed area ; 

 that of the Mersey, on authority of the Flora of Liver- 

 pool, in which the P. communis is enumerated as an
