Our plant is without doubt Sir William Hooker's variety /?. of this 

 species ; which occurs very frequently at all the above groups of 

 islands, and has the faculty of producing new individuals from 

 viviparous buds, formed on the thick black roots. Fronds tufted, 

 from 6 to 15 inches long, somewhat rigid, pinnate. Pinna? distant, 

 at least next the base, spreading; the ultimate divisions narrowly 

 linear-filiform, beset with bristle-like scales throughout. Rhachis 

 broad, compressed, and margined by flat edges. Stipe from 2 inches 

 to a span long, of a dull brown colour, subterete, ancipital, the 

 margins widening towards the base of the frond. Indusium small, 

 free, supra-axillary, cylindrical, slightly curved and attenuated at the 

 base; the mouth entire and spreading. Receptacle slightly exserted. 



The difference between this and the type of the species consists in 

 the presence of capillary palese on the surface of the whole plant, and
