Referred by us, without a doubt, as identical with the plant cited 

 in Hooker's Species Filicum. 



2. Stnaphlebium pulchrum, Sp. Nov. 



JS. rhizomate gracili repente; stipite quadrangidari nudo fronde bre- 

 viore; frondibus oblongo-lanceolatis pinnatis; pinnis subcoriaceis 

 alternis patentibus subsessilibus dimidiato-oblongis obtusis, margine 

 superiori lobato-crenato, inferiors costaformi sursum curvato, basi 

 truncato-cuneata; soris oblongis per totam latitudinem loborum con~ 

 tinuiis indusio proprio margine breviore. 



Hab. Tutuila, Samoan Islands; and Sandalwood Bay, Feejee 

 Islands : in mountain forests, on trees. 



Rootstock slender and creeping, about the thickness of a pigeon's 

 quill, rufous-hirsute. /Stipe 4 inches long, quadrangular, straw- 

 coloured, naked, shorter than the frond. Fronds oblong-lanceolate, from 

 4 to 6 inches long by an inch broad, somewhat coriaceous, pinnate. 

 Pi?mo3 from 25 to 30 in number, alternate, spreading, subsessile, di- 

 midiate-oblong, obtuse, from 4 to 6 lines in length by 3 lines broad, 

 approximate, the base truncate-cuneate, the inferior margin costwform 

 and curved upvmrds, the superior one lobate-crenate ; the crenatures 

 soriferous. Sori oblong, with a membranaceous continuous special 

 indusium, which is shorter than the margin. Veins forming elongated 

 meshes, 2 or 3 of them combining in each lobe, and forming the inter- 

 rupted sporangiferous receptacle. 



We view this as a very distinct species ; yet, at first sight, it might 

 be mistaken for the Lindswa cultrata of Swartz ; which however has 

 a forked venation. In the present genus our plant would stand next 

 to the S. recurvatum of J. Smith. 



3. Synaphlebium Pickeringii, Sp. Nov. (Tab. 30.) 



S. rhizomate gracili repente; stipite angulari basi squamoso; frondibus 

 glabris lineari-ensiformibus pinnatis ; pinnis plurimis approximates 

 alternis membranaceis dimidiato-oblongis obtusis, margine inferiori 

 integerrimo, superiori obtuse lobato, basi truncato-cuneata; indusio
