Particular attention is given to citation of numbers of all the

 Athyrium. (The Phil. Journ. of Sc. C. Bot. III. p. 285—300 October, 

 1908). 



The author, at the beginning of his paper, remarks: "on the 

 basis of the most thorough anatomical study the group has received, 

 Milde many years ago declared the distinctness of Athyrium from 

 Asplenium, the close affin ity of the former to Dryopteris, and the 

 impropriety of the generic Separation of Athyrium and Diplasium."
