POLYPODIACEiE. 75 



27. STENOCHL^NA, J. Sm. 

 (Acrostichi Spec. Auct. Lomarl® Spec. Willd., Kaulf. Olfersi^i Spec. Presl.) 



The most obvious differences between this genus and Elaphoglossum 

 are the scandent habit of the species, and the usually pinnate fronds, 

 the pinnae articulated with the rhachis. 



1. Stenochl^ena oleandr^folia, Sp. Nov. 



S. rhizomate scandente; stipitibus glabris basi teretibus paleaceis; fron- 

 dibus coriaceis latis pinnatis; pinnis petiolatis, sterilibus late lineari- 

 lanceolatis acuminatis basi oblique cuneatis margine integerrimis 

 recurvis, fertilibus linearibus elongatis acutis basi rotundatis margine 

 leviter undulatis; rhachi paleacea hirsuta. 



Hab. Feejee Islands : ascending the trunks of trees. 



Rootstock long and climbing, about the thickness of the little finger, 

 and almost entirely concealed by ochraceous, long, slender, submem- 

 branaceous paleae. Stipes smooth, about 5 inches long; both kinds 

 about equal, nearly terete at the base, with a shallow groove in front 

 towards the base of the frond, and densely covered with long, slender, 

 reflexed and twisted, brown paleaz. Both kinds of fronds are about 

 equal in size, broad, from 15 to 18 inches long, very coriaceous, 

 pinnate. Pinna? from 12 to 14 in number, about a span long, petio- 

 late; the petiole very distinctly articulated with the rhachis; sterile 

 ones 9 lines broad, linear-lanceolate, tapering rather suddenly into 

 a short acuminate point, the base obliquely cuneate; the margin rather 

 thick and recurved: fertile fronds 3 to 4 lines broad, long-linear, acute, 

 with a rounded base and a somewhat undulated margin,
