material is abundant in forms, the number of each specimen is insufficient 

 or incomplete. 



A. australasicum Hk., united by Baker and Christensen with A. nidus 

 L., is perhaps distinct. According to Hooker's diagnosis and plate the 

 fronds are somewhat panduriform, narrowed gradually from a very broad 

 upper part towards the base and then somewhat dilated again, not narrow 

 or decurrent. 



A. nidiforme v. A. v. R. has the fronds cuneate-spathulate, decurrent 

 at the base, provided beneath wit small deciduous squamules which are 

 long-filiform or stellate-fimbriate into long-filiform laciniae. 



A. simplex Mett. (not Bl.), referred by Hooker to A. phyllitidis Don 

 and by Christensen to A. nidus L., is unknown to me ; the Buitenzorg mat- 

 erial referrible to it has the rhizome and fronds of A. nidus and the sori 

 of A. phyllitidis, though shorter. 



A. phyllitidis Dort, united by Christensen and others with A. nidus L., 

 should be separated from the same as being undoubtedly distinct. As far 

 as one of our Philippine specimens shows, the fronds are tufted, not nest- 

 forming; all our specimens have the fronds distinctly stalked (stalks to 4 cm. 

 long), cuneate or decurrent at the base and provided with long sori only 

 separated from the margin by a rather narrow sterile space, separated from 

 each other by the sterile posterior veinlets of the branched veins. 



A. pachyphyllum Kze is unknown to me. The Buitenzorg material 

 referrible to it is very like A. phyllitidis Don; it differs in having the sori 

 much shorter.

Asplenium paradoxum, Bl., Enum. PI. Jav., II, 179; v. A. V.R., Mai.

A specimen cultivated in the Buitenzorg Gardens has some of the 

 sori partly scolopendrioid, partly diplazioid.

Bunnemeijer's No. 2240 from Banco {Bentja, Toboali) differs from 

 Hooker's and Beddome's diagnoses and plates in having the pinnae subentire 

 or slightly crenulate, and narrowly rotundate-cuneate at the lower base.
