SPICILIGIUM FILICUM PHILIPPINENSIUM.

perhaps referable to the above species which seems to be widely distributed in 
the Philippines. D. petiolare Presl, Epim. 446, a species that I have not seen, 
differs, according to the description, in its linear pinnae and pubescent rachis. 
Diplazium silvaticum is to me more and more a “collective species” worthy of 
being segregated into several distinct forms. 
31. Diplazium atratum n. sp. 
Stipite 25 cm. et ultra longo basi inerassito cligiti diametro sulcato, 
ebeneo aut atroviolaceo, opaco uti tota planta, basi latere ventrali more 
cyathearum squamis subulatis 1.5 cm. longis nigris dense vestito, planta 
aliter subnuda aut minute furfuracea, fronde late deltoidea acuta 60 cm. 
et ultra longa basi 45 cm. et ultra lata, bipinnata, pinnis remotis petiolo 
2 ad 3 cm. longo praeditis superioribus snbsessilibus, recte patentibus, 
utrinque ca. 20, infimis haud reductis, usque ad 30 cm. longis, 10 cm. 
latis, longe acuminatis, basi attenuatis pinnulis ca. 20 infra apicem 
incisum ultra 1 cm. distantibus, recte patentibus inferioribus petiolulatis 
e basi lata lanceolato-acuminatis, ultra mediant laminam basique fere 
ad costam incisis, lobis ca. 15 utrinque porrectis 3 mm. longis trigono- 
falcatis acutis margine serrulato saepe reflexo pinnis superioribus pinnulis 
similibus, nervis 4 ad 7 utrinque obliquis crassis simplicibus, soris nervosa 
costa fere ad marginem segmentibus valde obliquis convexis atrobrunneis, 
linearibus simplicibus, indusio lineari coriaceo brunneo persistente. 
Fronde glabra, textura rigide, fere lignoso-coriacea, colore atrofusco, 
opaco. 
Palawan, Victoria Peak (714, 683, 663 Foanvorthy) March, 1906, alt. 600 to 
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 pinnse petioled, the pinnules narrow 
and deeply incised, the lobes angular, narrow, their margins reflexed, the stipe 
and axial parts black, the frond itself blackish. The species has the general 
appearance of a Dicksonia or a Cyathea. 
32. Diplazium crenatoserratum (Blume^Enum. 177, Asplenium) . 
Mindanao, San Ramon (1667 Copeland) March, 1905, alt. 650 m. 
This species has not previously been reported from the Philippines; the above 
specimen matches material in my herbarium from Singapore leg. Hose, Java 
leg. Lefebre, Borneo leg. Grabowslcy, Hose, Niewenhuis, Celebes leg. Sarasin and 
Sumatra leg. Schneider. 
33. Diplazium Smithianum (Baker) Diels Nat. Pflanzenfam. 1 4 (1889) 
228. Asplenium Smithianum Baker Syn. 245. 
I am unable to distinguish from this species No. 2667 Merrill from Bosoboso, 
Rizal Province, Luzon, determined by Copeland as D. dolichosorum Copel. The 
type of Copelmid’s species is from Mindanao and he does not mention the Luzon 
plant in his diagnosis. Loher has previously found D. Smithianum in Luzon, 
and I have specimens from Celebes, leg. Sarasin, Koorders and Warburg (No. 
15314) -and from New Guinea, Sattelberg, Wemland, 1890. It is also found in 
Ceylon.
