Angiopteris evecta, Hoffm. ex Sw. Syn. Fil. p. 166 & 395; Willd. Spec. PL 5, p. 69;

Hae. Tahiti, Society Islands. Samoan and Feejee Islands. 



Trunk from 2 to 3 feet high and 1 J to 2 feet in diameter, composed 

 externally of thick and succulent, blackish scales ; the whole crowned 

 with from 10 to 15 luxuriant, spreading, bipinnate fronds, which 

 measure from 12 to 16 feet in length, including the stipe. Plants of 

 the above dimensions were found in deep valleys, in the mountain 

 forests of Tahiti ; while on Savaii, one of the Samoan Islands, Dr. 

 Pickering observed even larger individuals. By the aid of a lens we 

 find faint indications of a nerve, arising from the sinus of the teeth 

 of the pinnules, and running inwards parallel with and equidistant 

 between the veins, terminating near the costa. A similar nerve is 

 said to exist in the A. longifdia, of Hooker and Greville. 



2. Angiopteris attenuata, Sp. Nov. 



A. arborescens; frondibus bipinnatis; pinnulis suboppositis lineari- 

 lanceolatis attenuatis margine dentatis apice serratis basi cordato- 

 truncatis; rhacJii subtus parce paleaceo-liirsuta ; vends simplicibus 

 furcatisve nervo intermedio pellucido adjecto; soris intiwmarginalibus 

 approximate.
