SnCILTCIITM PILICUM PHILIPPINRNSIUM. 163 



perhaps referable to tlie above species wliicli seems to be widely distributed in 

 tlie Philippines. D. jwUolare Presl, Epim. 446, a species that I liave not seen, 

 differs, according to the description, in its linear pinnae and pubescent rachis. 

 Diphizium silrolieum is to me more and more a "collective species" worthy of 

 being segregated into several distinct forms. 



.31. Diplazium atratum n. sp. 



Stii^ite 25 cm. et ultra longo basi incrassito digiti 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 Miperioribus subsessilibus, recte patentibus, 

 utrinquo 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 mediam 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 -t ad 7 utrincjue obliquis crassis simplicibus, soris nervosa 

 costa fere ad marginem segmentibus valde obliquis convexis atrobrunneis, 

 linearilnis simplicibus, indusio lineari coriaceo brunneo persistente. 

 Fronde glabra, textura rigide, fere lignoso-coriacea, colore atrofusco, 

 opaco. 



Palawan, Victoria Peak (714, 08.3, 003 Foooioorthy) March, IflOG, alt. 000 to 

 1,100 m. 



The plant witli its liard woodj' 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 parts black, the frond itself blackish. The species has the general 

 appearance of a Dicksonia or a Cyafhea. 



32. Diplazium crenatoserratum (Blume Eniun. 177, Asplenium) . 



MiNDANAO, 8an Ramon (1007 Copeland) March, 190.'), alt. 0,50 m. 



This species lias not previously been reported from the Philippines; the above 

 specimen matches material in my herbarium from 8ingapore leg. Ilose, Java 

 leg. Lefehre, Borneo leg. Graboicsky, Hose, Nietoenhuis, Celebes leg. Harasin and 

 Sumatra leg. Schneider. 



33. Diplazium Smithianum (Baker) Diels Nat. Pflanzenfam. 1* (1889) 

 228. AspIcDium i^Diithianum Baker 8yn. 245. 



I am unable to distinguisli froni this speeies No. 2007 Merrill from Bosoboso, 

 Rizal Province, Luzon, determined by Copeland as D. dolichosorum Copel. The 

 type of Copelaoid^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 specimcns from Celebes, leg. «Voro.sui, Koordcrs and Warburg (No. 

 15314) and from New Guinea, Sattelberg, Weinland. 1890. It is also found in 

 Ceylon.
