were somewhat bent repeatedly switch-back fashion. 

 Some of the fronds, however, differed markedly from the 

 rest, which had plain edges, by having these edges deeply 

 cut so as to form fringes and such fronds had the other 

 undulate characters also enhanced, rendering these very 

 distinct and more beautiful than the rest. From this fact 

 it was clear that in some mysterious fashion, the mother- 

 cells, which start the formation of the future fronds, were 

 of different tendencies and hence asserted their structural 

 powers on different lines. 



The writer when he made the acquaintance of this fern 

 noted that the tips of the fringes produced on the more 

 abnormal fronds under moist conditions, expanded and 

 became translucent, and was thereby induced to sever 

 some of these experimentally in the belief that, as with 

 other ferns producing similar growths, plants might be 

 raised aposporously therefrom, that is, that these growths 

 might expand, produce prothalli which normally is the 

 function of the spore and so reproduce the plant. This 

 turned out to be the case and, in his hands and others, a 

 considerable number of plants were so raised. As usual, 

 however, with ferns so produced, the progeny varied much, 

 the two structural tendencies we have described asserting 

 themselves in varied degrees. It would appear, however, 

 that now and again the, what we may term superior, 

 type prevailed entirely and hence in a few years, a visit to 

 Walton to Mr. H. Bolton resulted in the acquisition of 

 a small plant which eventually developed into one which 

 we named S. v. Dvummondiae supcvhum in which no 

 tendency to reversion appeared, while the fimbriated, 

 undulated and crested features were so considerably 

 advanced as to fully justify the new name. A very fine 

 specimen of this was shewn in our Frontispiece of March, 

 1914, as grown by our member, Mr. C. B. Green. From this, 

 however, it will be seen that the cresting character of the 

 variety still left much to be desired, though the rest of the
