Closely allied to the G. australis of Robert Brown, the fronds of 

 which have a short pilose stipe; and, judging from a figure of it in 

 the Voyage of the Astrolabe and Zelee, that species is ca3spitose; 

 while in our plant the rootstock is creeping, and the hairs at the base 

 of the stipe are wanting.

1. Calymmodon hirtus, Sp. Nov. 



C. ccesjjitosus ; stipite brevi alato; frondihus linearibus jprofijm.de pin- 

 natifidis hirsutis; pmnis inferioribus sterilibus oblongis obtusis, supe- 

 rioribus sidioblongis cucidlatis monosorosis ; soris oblongis. 



Hab. Mount Majaijai, Philippine Islands : on trees. 



The plant is 3 to 4 inches high, cmspitose, with a short winged 

 stipe, about one-fourth of an inch in length. Fronds linear, deeply 

 p'mnatifid, membranaceous, of a pale straw-colour, and with long 

 hairs on both sides. Lower segments oblong, obtuse, distant, and sterile. 

 with the sinus rounded ; those of the upper half of the frond some- 

 what oblong, cucullate, and bearing within the cowl near the point a 

 single oblong sorus. 



This appears to be altogether distinct from the C. cucullatus of 

 Presl, which has subcoriaceous and glabrous fronds, quite destitute 

 of hairs.
