Hab. Mount Maijaijai, Luzon, Philippine Islands.

 Hab. Mountains near Banos, Luzon, Philippine Islands.

 attenuated at both ends.

Hab. Sandwich Islands : on trees ; frequent. 



Rootstock short and creeping, of a sooty-brown colour, paleaceous-

 and beautifully reticulated. Fronds from 3 to 6 in a tuft, usually 

 erect, from 5 to 30 inches long, and averaging 2 lines in breadth, 

 plane, rigid, linear-ensiform, tapering more towards the base than 

 the point, which sometimes presents a truncated appearance, as if 

 bitten off by some animal ; the costa on the lower half of the frond is 

 evident. 



The fronds of this species vary much in length : in dry exposed
