13. Dryopteris basilaris (Presl) C. Chr. Ind. Fil. (1905) 254. Nephrodium 
basilare Presl Epim. Bot. (1849) 258, nomen. 'Nephrodium philippinense Bak. 
Ann. Bot. 5 (1891) 327. 
This species is one of the most distinct, most important and most widely 
distributed of the genus in the Philippines, and is characterized by Baker as 
follows : 
“Rootstock and complete stipe not seen. Frond oblong-lanceolate, bipinnatifid, 
2-3 ft. long, 1-1 J ft. broad, moderately firm, glabrous, rachis naked. Pinnae 
lanceolate, acuminate, 8-9 in. long, i in. broad, cut down less than half way to 
the rachis into oblong erecto-patent lobes 5 in. broad, lower pinnae not dwarfed, 
veins simple, 8-9 jugate. Sori medial, indusium firm, glabrous, persistent. 
Near arbuscula, but lower pinnae not gradually dwarfed.” 
It was on specimens Nos. 10, 84 and 338 Cuming that Baker based his 
imperfect description, and of these I have before me a specimen of the second 
number. Based on this number, and the abundant material collected by the 
American botanists in the Philippines, the following detailed description is given : 
Rhizomate obliquo suberecto valde radicoso crasso, foliis subf asciculatis 
(4 ant 5) stipite basi sulcato-dilatato, squamis subulatis usque ad 2 cm. 
longis brunneis e basi lanceolata filiformi-elongatis vestito, rufostramineo, 
glabro lucente, tereti, basi pennae cygni crassitie, 45 cm. longo, fronde 
usque ad 65 cm. longa, 20 'em. lata late ovata acuminata, pinnata, basi 
abrupte terminata, pinnis infimis haud abbreviatis, sed stipite utrinque 
8 aut 10 auriculis obtusis rudimentariis remotis instructo, pinnis alternis 
erecto-patentibus numerosis sessilibus aut brevissime petiolatis, pinna 
terminali saepius valde elongata aut basi bifida, pinnis lateralibus approxi- 
matis, ca. 35 utrinque, 14 cm. longis, 1 cm. latis caudato-acuminatis lan- 
eeolato-linearibus, basi antiore recte truncata, posteriore semicorclata, 
marginibus lobatis usque ad tertiam partem, lobis decumbentibus 3 mm. 
longis oblongis subobtusis, costis pallidis manifestis, nervis 5 ad 8 utrin- 
que, infimis aream unam formantibus, soris minutjs-mediis 5 utrinque, 
indusio griseo persistente. Colore brunneo-viridi, textura subeoriacea 
rigidiuscula, planta glabra.

Widely distributed in the Philippines; endemic. 
14. Dryopteris Luzonica n. sp. 
A species, resembling the preceding, and like it widely distributed in Luzon, 
but well characterized by its very thin texture, bright green color, its pinnae 
horizontal, in rather remote pairs and dilated at the base, the lobes obtuse,
