ADDITIONAL SPECIES, ETC. 325 



lishecl Catalogue of Caermartlienshire plants, now depo- 

 sited, I am told, with some provincial society ; but since 

 no other botanist has found the P. amara there, so far as 

 I can ascertain, it would seem safer not to include the 

 province of South Wales in the area and census of the 

 alleged species at present. (See vol. i. p. 186.)

 whom I am indebted for a specimen, this sj)ecies may now 

 be admitted among British plants with much less of 

 distrust than formerly attached to it. The species in 

 itself was likely enough to be found in Britain, consider- 

 ing its geographical distribution to include the Pyrenees, 

 Alps, Norwegian mountains, Iceland, &c. In the sixth 

 edition of the British Flora, however, it is rejected as a 

 native, with a remark on the Clova station, to the effect 

 that the Authors " have strong reasons for thinking that 

 the plant was sown there, about 00 years ago. The Cum- 

 berland habitat is perhaps as doubtful." This remark 

 appears directly to make the honesty of George Don, 

 senior, a mooted question ; and the answer to such a
