NovemBer 15, 1910] Toe Ferns or Mount Apo 799 
integris, infimis non vel solummodo uno latere diminutis, gla- 
bris, coriaceis, planis, infra pallidis non glaucis; venulis 
furcatis. 
Mt. Apo, alt. 1850 m., No. 11423*. 
While most readily recognized by its stalked pinnae, 
this species differs from any others known to me in the 
closeness and uniformity of the paleae of the rhachises and 
lower part of the costae, on both surfaces but especially 
above. 
Gieichenia Elmeri Copel. spec. nova. 
Species altera gregis G. japonicae Spr. ob segmenta re- 
mota distinctissima. Rhachi scandente usque 12 m. alta, ultra 
1 em. (teste Elmer) crassa; pinnis fere 1 m. inter se distan- 
tibus, 150 em. longis, recurvis, sessilibus, rbachidibus fere 
glabris, castaneis, nitidis; pinnulis infimis stipulaceis, aliis 
brevi-pedicellatis, maximis ultra 25 cm. longis, acuminatis; 
segmentis remotis, deorsum 5 mm. inter ‘se distantibus, in- 
fimis interdum paullo diminutis, linearibus, rectis vel eurvis, 
integris vel rarius crenatis, coriaceis, infra arachnoideo-paleaceis 
et pallidioribus, ala angusta connexis; soris paginam totam 
fere complentibus, sporangiis 4-7. 
Mt. Apo, in very damp woods, alt. 1650 m., No. 11423. 
*"l'angiras.?' : 
From the lowest segment, the wing runs down onto the 
rhachis, on which, entirely losing its foliaceous character, it 
forms a pronounced ridge. | 
The Bagobos use the stipes and rhachises for tieing and 
weaving. Related species are used in the Philippines for de- 
corative purposes, such as making light picture frames, for 
which the rich color and shiny surface fits them well, and, 
at least in an experimental way, for hat making. The most 
important ferns in this respect are, however, the Lygodia. 
These and the climbing stems of Stenochlaena are articles of 
commerce in various parts of the Islands. The Stenochlaena 
has diverse uses, including the calking of boats.
