Near this and possibly to l>e included, are Bur. 8ci. 5] 20 llamos from 
Zambalus, and Bur. For, JiG/,2 Mcarns tC- Hntclibison, from Mount Malindang, 
Mindanao. The former suggests A. cyathcaefolium in its form, but it belongs 
rather in this group.

New Guinea and beyond. 
Asplenium. cyatheaefolium was originally a New Guinea fern (Of. 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, liere 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 Meltenius 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 atraium Christ in 
Philip. Journ. Sci. 2 (1907) Bot. 163. 
Palawan, Bur. Sci. 714, G83, 603 FoxworlUy: Zanibales, Bur. Sci. 5127 Ramos, 
Ramos' plant is reddish in cast, and further lightened iu color by the copious, 
more or less confluent sori. Still it is certainly this species, as shown by the 
pubescent axes, and the rachises of the pinnae, characteristically arched just above 
their insertion. 
18. Athyrium oligosorum Copol. comb. nova. Diplazium oligosorum Copel. in 
. Philip. Journ. Sci. 2 (1907) Bot. 128. 
Mount Halcon, Mindoro, Merrill 50J3. Bur, Sci. 27^0 Meanis from Benguet, 
and Elmer 9991 from Negros are very near this. 
GROUP OF A. SILVATICUM. 
19. Athyrium silvaticum (Bl.) Milde, 18GG. Allantodia, Bl. Enuni. (1828) 
173. Tirachysorus wood war dioides Presl Epim. (1849) 70, Asplenium, Baker, 
Copel. in Polypodiaceae, 87. Athyrium hasilare F6e.

San Ramon, Copeland lJt93a; Mount Apo, Copcland 1^93, JS^illiams 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 ^findanao 
specimens cited here is more or less erect, and may reach a height of GO cm.
