This species has, according to the diagnosis and figure given by 

 HOOKER, mentioned above, the stipe and rhachis black, the leaflets aiternatc 

 except the opposite lower ones, the terminal leaflet elongate-oblong, iiicised 

 on both sides, bluntish at the narrowed tip, the lower leaflets somewhat 

 remote. 



The Buitenzorg Herbarium possesses no authentic material of this 

 species but it has a plant from an unknown habitat, occurring under this 

 name. agreeiiig very well with HooKER's figure; it has, however the stipe 

 and rhachis stramineous, quadrangular. 



The Herbarium received under the name of L. adiantoides j. Sm a 

 plant from the Philippines that agrées very wel! with the very incomplète 

 diagnoses given by HoOKER, HoOKER and BAKER in Syn. Fil., 104, 

 Copeland in Polypod. Philipp. 62, but it differs absolutely from HOOKER's 

 figure mentioned above. so that I am inclined to consider it as a species 

 différent from this, supposing that hiOOKER's figure is correct. If 1 am right. 

 1 propose to call it :
