indusoiii margin also agrees, but the teclinical 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 

 hj 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 Ijeing no specimens 

 of tlie fronds attached to the caudex in the Herbarium.
