eradicated. I think it will not be deemed extraordinary or eccentric after 

 such an instance, if T merely record that Asplenium septentrionale 

 still exists near Llanrwst in very great profusion and luxuriance, in 

 enormous tufts, readily to be removed from between the stones, and 

 that Asplenium germanicum occurs more sparingly. 



While on the subject of these Aspleniums, I may perhaps be allow- 

 ed to introduce to the notice of the readers of the ' Phy tologist ' the 

 following interesting note from Mr. Smyttan, of Cambridge : — 



" After reading to-day your remarks in your very interesting work 

 on British Ferns, on Asplenium alternifolium, I have thought it might 

 be interesting to you to know that I found a specimen of this very 

 rare plant on Stenton Rock so lately as last summer. After two 

 hours' climbing on the bare rocks in one of the most burning days, I 

 at last found the treasure in a fissure of the barest part of the rock. 

 I am sorry I cannot send you a part of the specimen, as it was a very 

 small plant, and I gave a friend one half, the other I have in my 

 small collection. 



" Septentrionale grows in great abundance on this rock.

Notes on the affinity between Lysimachia nemorum (Linn.) and Ly- 

 simachia azorica (Hornem.). By Hewett C. Watson, Esq. 



Tn some remarks on certain of the specimens distributed last 

 winter by the Botanical Society of London (See Phytol. ii. 766), I al- 

 luded to the close affinity between the two plants (I know not whether 

 to say ' species ' or ' varieties ') above named ; in illustration of which 

 some examples of the L. azorica had been then recently distributed for 

 comparison with our native L. nemorum. It was intimated that an 

 explanation would be afterwards given in respect to the grounds for 

 sending out specimens of an Azoric species in the parcels of British 

 plants ; which I propose to do here. 



Independently of its bearing upon the distinctions of species for the 

 objects of technical description, a very near affinity, without complete 

 identity, between plants of distant islands, gives rise also to questions 

 of much interest in connexion with vegetable geography and physi- 

 ology. It bears intimately on the often vexed question of what is a
