pcrliaps referable to the above species wbicli seems to be widely dialributed in 
the Phiiippines. D. pciiolare Presl, Epiin. 446, a spt'cies tliat I have not seen, 
differs, according to the description, in its linear pinna* and pubescent racltis. 
Diplazium silvaticum is to me more nnd more a "collective species" worthy of 
being segi'ogatod into several distinct forms.

1,100 m. 
The plant with its hard woody texture and its dark color must be in sharp 
contrast to the surrounding vegetation. It is a very stiff coriaceous species 
.with ample, deltoid, bipinnate fronds, the pinnae petioled, the pinnules narrow 
and deeply incised, the lobes angular, narrow, their margins reflexed, the stipe 
and axial jiarts black, the frond itself blackish. The species has the general 
appearance of a Diclsonia or a Cyaihca.

I am unable to distinguish from this species No. 2GC7 Merrill from Bosoboso, 
Rizal Province, Luzon, determined by Gopeland as D. dolichosorum Copel. Tlie 
type of CopcUt)uVs species is from ATtndanao and ho does not mention the Luzon 
plant in his diagnosis. Loher has previously found D. Smiffnonum in LuzON, 
and I have specimens from Celebes, leg. Sarasin, Koorders and Warburg (No. 
15314) and from New Guinea, Sattelberg, M^Hnland, 1890. It is also found in 
Ceylon.
