An interesting fact which may not be known to some 

 of the members of the American Fern Society is the 

 occurrence of Asplenium platy neuron in South Africa 

 and elsewhere only in eastern North 'America. Several 

 instances of such distribution are known.

Nephrodium Kuhnii Hieronymus is re-named Also- 

 phila Kuhnii by Christensen, because of its basal in- 

 dusium, of a type common in the tree-fern family, but 

 unknown in Dryopteris. It is the smallest "tree-fern" 

 known, being only eight inches long. 



Alsophila phalenolepsis is a brand new species Jrom 

 Ecuador of a considerably larger size, (leaves 

 inches long), somewhat like A. phegopteroidea Hooker.

In this paper, Christensen lists seventy-eight species 

 as the total number known from the Seychelles Islands. 

 As he notes, Baker, in 1877, recognized seventy-four 

 species, and Kuhn in 1879, recognized seventy-six. 

 When it is noted that four of the species in the P re * ent 

 papers were collected for the first time in 1908, it will be 

 seen that the lists of Baker and Christensen recognize 

 exactly the same number of species. This fact is of 

 especial interest in view of the opinion sometimes ex- 

 presses as to the prevalence of species "splitting. 

 According to one view of modern taxonomy, Christen- 

 sen would have been expected to recognize no fewer than 

 one hundred and fifty species. Naturally the treatment 

 differs from the earlier ones in its nomenclature, that ot 

 the Index Filicum beins- followed in the main. 



The Seychelles Islands are extremely interesting owing 

 to their location so far distant both from the Asiatic and
