1684 Leaflets of PniLippixs Botany [Vol. V, Akt. 90 



Pteris opaca J. Sm. 



After studying Elmer^s plants, I doubt the distinctness 

 of P. Taenitis Copel., described from the same region. 



Polypodium stenophyllum Bl. No. 14146, alt. .1850 ni., 

 Manobo name Xotong-notong. 



Remarkably large and acute fronds. In view of Blume's 



expression "Frondibus obtlisis," it seems to me that 



ChrisVs variety oblwium should rather he regarded afl the 

 typical form. 



Polypodium halconense Copel. No. 13761, alt. 1800. m. 



The second collection of this interesting fern. It is a 

 connecting link between the P. tenuisectum group and the 

 body of the genus. 



Elaphoglossum Elmeri Copel. No. 13746, alt. 1400 m., 

 Manobo name Dohus-dohus. 



The only previous collection is Elmer's from Mt. Calelan. 

 The new specimens have larger froi.ds, but are otherwiee 

 identical.
