Hab. Ovolau, Feejee Islands. 



Stipes and fronds smooth, about equal in length, of a straw colour ; 

 the latter broadly-ovate, obtuse, membranaceous, and a little more 

 than a foot long, pinnate at the base and deeply pinnatifid towards the 

 paint. Pinnae, distant, alternate, divaricate, lanceolate, attenuate, from 

 6 to 8 inches long and 10 lines broad, the margin sinuate-dentate, and 

 base of the two or three inferior pairs cuneate and decurrent on the 

 rhachis. Khachis and costa smooth, of a straw colour, naked and pro- 

 minent on the under side. Sori most profuse towards the summit of 

 the frond, small, round, scattered, and distant.

13. Drynaria coadunata, Sp. Nov. 



D. stipite acute angulato paleaceo; fronde glabra membranacea basi 

 pinnata ve?*sus apicem pinnatifida; pinnis suboppositis divaricatis 

 oblongo-lanceolatis sinuato-pinnatifidis, infimis petiolulatis triangu,- 

 laribus basi obliquis, laciniis triangidari-ovatis obtusis crenatis; rhachi 

 costaque glanduloso-pubescentibus ; soris numerosis parvis rotundis 

 sparsis. 



Hab. Sandal-wood Bay, Feejee Islands : in mountain forests. 



Stipe sharply angled, of a dark brown colour, sparsely furnished 

 with long, slender, fugacious, chaffy scales. Fronds glabrous, membra- 

 naceous, about 2 feet in length, ovate-oblong, acute, cordate, and pin- 

 nate at the base: the pinnae confluent upwards and forming a deeply 

 serrate point to the frond ; the lowest pair triangular in outline and 

 oblique at the base, with 2 or 3 large triangular-ovate, lobate-sinuxite, 

 obtuse segments on the lower side. 



We find no published species with which this satisfactorily agrees. 

 It is altogether distinct from any Fern in our collection, and was 

 detected only once in the above-mentioned locality.
