The sori are shorter than in other British Asplenia^ characteristic 



of Athijrium Roth. — Mr. Newman and Mr. Babin^ton have a var. 



tte, es- 



^7 violle (Athyrium molle. Roth), from a sea^cave, Aberdeen; but if the 



specimen we received from Mr. Moore from that same hx^ality (culti- 

 lantlie ' vated indeed) be the same, we do not see how it differs from our var, 



p. latifolium. We should probably have been of the same opinion, 

 only that, among our numerous specimens of A, Filix foemina, we 

 find .intermediate states; one from Awatschaka Bay, Kamtschatka ; 

 another from Crete (Heldreich), " Athyrium no v, sp.'' The authors 

 above mentioned have a var. convexum ; which appears to us to be a 

 common state of our a. — This plant would appear to grow in very 

 wet shady places, and to be altered in consequence. Mr. Newman 

 gives a faithful representation of a curious monstrosity of A, Filix 

 fcemina (Brit. Ferns, p. 248.) with very changed fronds, the main 

 and partial rachis divided at the extremity in a corymbose manner: 

 it retains its peculiarities in cultivation.
