Judging from Baker's description this plant dues not agrée 

 with Blnme's plant, which lias the lower pinnae pinnatifid and 

 not 2-pinnatifid at the base. A form found in Sumatra by D 1 '. 

 Burck agrées with Baker's diagnosis, it has the rhizome erect, 

 densely clothed with rather long, linear-subulate, fuscous scales, 

 the stipes tufted, sparingly scaly like the main rachis, the ulti- 

 mate lobes oblong, acute, entire to broadly toothed, the sori 

 distant from the margin, + medial between the costulae and 

 the edge, and tw r o plants gathered in Bornéo and cultivated in 

 the Buitenzorg gardens, which may be forms of this species hâve 

 the fronds under 30 cm. long, the ultimate lobes linear, narrow- 

 ecl gradually towards the apex, the sori submarginal. - - After 

 Christensen's natural System this plant should be called Aspi- 

 dium Bakeri and after Copeland's conception Tectaria Bakeri,

Val*, aspei'a {Polypodium asperum, Zipp., MS. in Herb. 

 Bog): Differs from Mr. Backer's Krakatau plant in having the 

 rachises not beset with flat, subulate scales, but with subulate, 

 subterete bristles of the same coulour, the pinnulae horizontally 

 spreading, the tertiary segments rather small, with the edges 

 much recurved when dry. Indusium somewhat larger, visible 

 °y i 15X magnifying power, but also hidden between the 

 capsules. Rhizome creeping. • Perhaps a distinct species.
