2. Antrophyum angttstatum, Sp. Nov. 



A. frondibus stipitatis coriaceis lineari-lanceolatis attenuatis dbtusis basi 

 decurrentibus ecostatis; sporangiis profunde immersis. 



Hab. Tahiti, Society Islands : on trees, in mountain forests. 



Rootstock short and creeping, paleaceous-hirsute ; the palese oblong, 

 much attenuated, beautifully and delicately reticulated, the margin 

 spinulose-serrate. Stipe 4 inches long, slightly compressed. Fronds 

 numerous, approximate, from 8 to 10 inches long, and about 6 lines 

 broad, coriaceous, linear-lanceolate, tapering gradually into a rounded or 

 sometimes acute point, the base decurrent a short distance on the stipe ; 

 the meshes of the reticulated veins much elongated : costa none. Sori 

 linear, continuous and naked; the sporangia deeply immersed in the 

 substance of the frond. 



From A. reticulatum this differs by its longer stipes, narrower 

 fronds, and deeper immersed sori.
