Mindanao, District of Davao, Mount Apo (1136 Copeland) April, 1904; 
(1614a Copeland) October, 1904, alt. 1,800 m. Luzon, Province of Benguet, 
Baguio (Loher) 1897, alt. 1,400 m. 
The same species has been found in Borneo, Sarawak, leg. Hose, 1894; Batjan, 
leg. Warburg ; Celebes, Lolcon, leg. Sa.rasin No. 719, 1894. 
It is related to D. fiUx mas, sensu latissimo, in spite of its extremely decom- 
pound frond and large size. In authentic specimens from Sarawak the segments 
are almost entire, while in those from other localities they are strongly dentate.

69. Dryopteris Preslii (Bak.) O. Ktze. Rev. Gen. PL 2 (1891)* 813. Nephro- 
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. obscura from its 
general appearance, although smaller in all its parts. 
Bohol (354 Cuming) “Lastrea spectabilis J. Sm.” in Hook. Journ. Bot. 3 
(1841) 412. There has been an error, apparently, in copying the label, as 
Lastrea spectabilis J. Sm. = Dryopteris Syrmatica, our specimen being entirely 
different from the latter species. (Baker indicates No. 255 Cuming as the’ type 
of Nephrodium Preslii.) 
Endemic.
