2CO CHAEACTEES OF TEIBES AND GENEEA. 



indusoid margin also agrees, but the technical character of 

 the sori distinguishes it. 



In " Ferns, British and Foreign," I have described the 

 vernation as erect, as shown by a young plant cultivated at 

 Kew, received from Dominica, which agrees with the words 

 " fronds tufted," as given in the " Species Filicum," whereas 

 the specimen in the Kew Herbarium collected in Jamaica 

 by Purdie is marked " Rhizome creeping ; this singular 

 Fern grows or rather climbs to a height of 20 feet." Of 

 the correctness of this I have doubts ; further observation 

 is required to determine whether the two known species of 

 the genus differ in their vernation, there being no specimens 

 of the fronds attached to the caudex in the Herbarium.

 or more soriferous. Receptacles terminal, punctiform, mar- 

 ginal or sub-antimarginal. Indusium attached by its broad 

 base only, or by its base and sides, constituting a simple,
