 beneath have long spreading luiirs.

 frond 3 feet long a foot and more wide ovato-oblong acunni- 

 nate coriaceous dark-brown when dry with a rufous tinge 

 especially on the stout rachis and costa beneath subglabrous 

 pinnated to the very acuminated apex, pinnce patent sessile 

 opposite below, the rest alternate 8-10 inches long from a 

 broad base an inch and more wide oblong gradually acumi-

 linear-oblong obtuse ol)scurely serrated at the apex, veinlets 

 approximate numerous 20-25 pairs deeply impressed on the 

 upper side very elevated beneath 2-4 of the lowest pairs 

 connivent, sori copious forming 2 compact lines between the 

 costule and the margins subconfluent. — Goniopteris costata,

Hab. Society Islands, in damp hollows, alt. 1000 feet, Bidwill, Brackenridge. 

 Fiji Islands, Brackenridge. — A noble and very handsome species. I have seen no 

 authentic specimen of it, but I cannot doubt our specimens from Mr. Bidwill being 

 identical with the Goniopteris costala, Brack. 



235. P. (Goniopteris) Jongissimum, Hook.; " subarborescent, 

 fronds large pinnate, pinnoe sessile horizontal subalternate 

 approximate coriaceous long-linear attenuate pinnatifid, seg-

 veins, sori small approximate." — Goniopteris, Brack. Fil. U.

Hab. High mountains of Tahiti, rare, Brackenridge. — " Trunk stout, erect, 2-3 

 feet high, crowned with large spreading pinnate fronds 3-4Yeet broad." I am in- 

 debted to Mr. Brackenridge for 3 pinmc of this Fern. They are U foot long and 

 1^ inch broad, but destitute of sori. I fear it is too near the P. cosfatum from the 

 same island ; the texture, venation, and the colour (rufescent) correspond.
