It is related to D. filix mas, sensii latissimo, in spite of its extremely decom- 
pound frond and large size. In autlientic specimens from Sarawak the segments 
are almost entire, while in those from other localities they are strongly dentate.

dium Preslii Baker Syn. Fil. 272. 
Baker's diagnosis is sufficiently clear to satisfactorily identify this plant. 
It is an insular dwarfed form that seems to be related to D. ohscura from its 
general appoai>Tnce, although smaller in all its parts. 
BoHOL (354 Cnming) "Lastrea spcciahilis J. Sni." in Hook. Journ. Bot. 3 
(1841) 412. There has been an error, apparently, in copying the label, as 
Lastrea spectahilis J. Sm.:= Dryopteris Fiyrmaiica, our specimen being entirely 
difforont from the lalter species. [Baker indicates No. 255 Cuming as the type 
of Nephrodium Preslii.)
