 lanceolatis basi cuneatis; laciniis cuneiformibus incisis, ultimis linea-

Trichomanes album, Blume ? Enum. PI. Jav. 2, p. 226. 



Hab. Mount Majaijai, Luzon, Philippine Islands : on trees. 



BootstocJc filiform and pilose. Stipe round, slender, smooth, from 

 one to 2 inches long. Fronds about the same length as the stipe, 

 ovate-oblong, bipinnatifid, both surfaces whitish, and with the margin 

 of the lacinise strigose-hirsute, the hairs of a pale brown colour. 

 Pinnce opposite, ovate-lanceolate, cuneate at the base; the lacinia? wedge- 

 shaped and deeply incised, the ultimate one linear, obtuse or slightly 

 emarginate at the point. Sori confined to the upper half of the frond, 

 and seated near the rhachis. Indusium supra-axillary, oblong, trun- 

 cate, the base partially immersed, the mouth truncate, the short receptacle 

 appears to be always included. 



We suppose this to be the T. album of Blume ; yet, as his short 

 description leaves much room for doubt, we have given a figure of it.
