continuation of the raid-rib. Structure of the frond does not essentially 

 differ from other related species (Fig. D). 



At first sight, the present plant very much resembles Caloglossa 

 Beccari Zanard., known from Sarawak ; but on closer observation, the 

 difference becomes at once manifest from the absence of petiole and the 

 lateral proliferations from the basal portion of segments. From the 

 point of distribution, the present species seems to be related to C. 

 mnioides, Haw., known in New Guinea, New Caledonia, and the Friendly 

 Islands; but this latter species which is very closely related to C. 

 Leprieurii (Mont.) J. Ag., differing only in its lanceolate-elliptical and 

 abruptly attenuated segments, does not seem to be unequally dichotomous 

 and to put forth lateral |irol iterations from the basal portion of segments.
