Yar. 8. frondibus sesqui-bipedalibus lanceolatis acutis apice undulatis 

 basi subattenuatis. 



Yar. s. frondibus tri-quaclripedalibus elongato-lanceolatis apicidatis mar- 

 gine crenatis. 



Hab. Sandwich Islands. Tahiti, Society Islands. Yar. p. Sand- 

 wich Islands; with elongated-lanceolate fronds, 2 or 3 feet long, the 

 point undulate and obtuse. Yar. y. Paumotu, Society, and Samoan 

 Islands ; also Tongatabu, Friendly Islands ; a form with lanceolate and 

 acute fronds, 3 or 4 feet long, attenuated at the base. Yar. I. Feejee 

 Islands; with fronds \\ to 2 feet long, lanceolate, acute, the point 

 undulate, the base slightly attenuated. Yar. e. Illawarra, New South 

 Wales ; a form with the fronds 3 or 4 feet long, elongated-lanceolate, 

 apiculate, the margin crenate. 



Usually only the upper half of the frond in all these forms is 

 fertile, and each venule is sporangiferous ; the sori commencing near 

 the costa and continuing outwards to within half an inch of the 

 margin. 



2. Neottopteris Phyllitidis, J". iSm. 



N. frondibus lanceolatis acuminatis integerrimis basi attenuatis subco- 

 riaceis; soris parallellis remotis; indusio membranaceo persistente. 



Neottopteris Phyllitidis, J. Sm. in Hook. Jour. Bot. 4, p. 176. 

 Asplenium Phyllitidis, Don, Prodr. Fl. Nepal, p. 7. 



Hab. Mountains near Baiios, Luzon, Philippine Islands. 



Fronds 2 feet long by about 3 inches broad, lanceolate, acuminate, 

 entire, subcoriaceous, with an attenuated base. Sori distant and parallel, 

 with a membranaceous persistent indusium. The habit is similar to 

 that of N. Nidus; from which it diners in the fronds being narrower 

 and more attenuated at the base than in the usual form of that 

 species ; the lines of sori are also more distant, only every second or 

 third venule being sporangiferous ; and the sori extend from the costa 

 to within two lines of the margin.
