1. Selliguea involuta. 



Grammitis involuta, Don. Prodr. Fl. Nepal, p. 14; Hook. & Grev. Ic. Fil. t. 53. 

 Hab. Samoan and Feejee Islands : high on the branches of trees. 



In a recent state, the fronds of this species are not involute ; and 

 although in our specimens they are not so large as represented in 

 the Icones Filicum, the plant is evidently the same. 



2. Selliguea alien a, Sp. Nov. 



S. rhizomate repente; stipitibus elongatis marginatis; frondibus integris 

 glabris membranaceis lanceolatis caudato-acuminatis basi attenuatis 

 margine repandis; soris obliquis coniinuis marginem vix attingentibus. 



Hab. Mountains near Banos, Luzon, Philippine Islands. 



The fronds are about 9 inches long, and li inches broad, smooth, 

 membranaceous, lanceolate, and terminating in a tail-like point, the base 

 decurrent on a slender margined stipe, nearly as long as the frond. 



Closely related to jS. ( Ceterach) paniculata of Hooker and Greville ; 

 but in our plant the fronds are much longer, both the base and the 

 point being more lengthened out, and the sori do not advance so 

 close to the margin. It is nearly allied also to the Grammitis mem- 

 branacea of Blume. 



3. Selliguea plantaginea, Sp. Nov. 



S. rhizomate repente squamoso; frondibus coriaceis glabris supra nitidis 

 oblongo-lanceolatis attenuatis basi leviter decurrentibus margine crebre 

 crenato-undulatis ; soris obliquis latis interruptis. 



Hab. Tahiti, Society Islands : terrestrial, in high mountain forests.
