Mount Data, Luzon, alt. 2,200 m, Copeland, s. n., Copeland 1868: Pauai, 
Benguet, alt. 2,100 in, Bur. Sci. 1/185, 1/186, 1/181 M earns. 
Near this and possibly to be included, are Bur. Sci. 5120 Ramos from 
Zambales, and Bur. For. 1/61/2 M earns & Hutchinson, from Mount Malindang, 
Mindanao. The former suggests A. cyatheaefolium in its form, but it belongs 
rather in this group. 
GROUP OP A. CYATHEAEFOLIUM. 
10. A. cyatheaefolium (Rich.) Milde. Asplenium, (Bory) Rich., Sert. Astrol. 
(1834) 19; Diplazium, Presl, Epim. 88. Diplazium cbenum J. Sm., but not D. 
caudatum J. Sm., which is A. meyenianum.

New Guinea and beyond. 
Asplenium cyatheaefolium was originally a New Guinea fern (Cf. Presl 1. c. ) , 
but is more generally known from Cuming’s Luzon collection. A specimen received 
by the Bureau of Science from the British Museum bears the statement on the 
label that this, here numbered 158, is 159 of Smith's herbarium. It is No. 158 
in the herbarium of the N. Y. Bot. Garden. Not having access to New Guinea 
specimens nor the original publication, I have construed A. cyatheaefolium as the 
British botanists have done, but am not sure to what fern Mettenius applied this 
name. The ferns I am including here are not identical, those from Luzon having 
a dark, more or less pubescent stipe and rachis, while those from San Ramon 
have the axes paler and glabrous. 
17. A. atratum (Christ) Copel. comb. nova. Diplazium atratum Christ in 
Philip. Journ. Sci. 2 (1907) Bot. 163. 
Palawan, Bur. Sci. Ill/, 683, 663 Foxworthy : Zambales, Bur. Sci. 5121 Ramos. 
Ramos’ plant is reddish in cast, and further lightened in color by the copious, 
more or less confluent sori. Still it is certainly this species, as shown by the 
pubescent axes, and the racliises of the pinnae, characteristically arched just above 
their insertion. 
18. Athyrium oligosorum Copel. comb. nova. Diplazium oligosorum Copel. in 
Philip. Journ. Sci. 2 (1907) Bot. 128. 
Mount Halcon, Mindoro, Merrill 5913. Bur. Sci. 211/0 M earns from Benguet, 
and Elmer 9991 from Negros are very near this. 
GROUP OP A. SILYATIOUM. 
19. Athyrium silvaticum (Bl.) Milde, 1860. Allantodia, Bl. Enum. (1828) 
173. Brachysorus icoodivardioides Presl Epim. (1849) 70, Asplenium, Baker, 
Copel. in Polypodiaceae, 87. Athyrium basilare Fee. 
Luzon, Cuming 153 ; Mount Banajao, Bur. Sci. 21/10 Foxworthy : Mindanao, 
San Ramon, Copeland ll/93a; Mount Apo, Copeland 11/93, Williams 2298. 
Celebes, Java. 
Foxworthy’s specimen and Cuming’s are altogether alike, but the Luzon plant 
is not fully identical with those from farther south. The caudex of the Mindanao 
specimens cited here is more or less erect, and may reach a height of 60 cm.
