PHILIPPINE FERNS: III. 33 
Mount Maquiling, 900 m. s. m. Copeland, P. P. E. 57; Mount Banajao, 
Whitford 999, forma major frondibus 35 cm. longis. 
This fern is well characterized by the position of the sori, the texture, and the 
surface. It is scandent, but has the characteristic stout, stiff stems and clustered 
leaves of 0 . neriiformis and 0 . colubrina. 
There is also on Maquiling an Oleandra, collected sterile by Dr. Matthew and 
myself, which has seriate instead of clustered leaves, with a long pedicel and 
almost no stipe. 
O. colubrina var. nitida Copeland var. nova. 
Frondibus usque ad 40 cm longis, 20 mm latis, coriaceo-papyraceis 
mox glabris, nitidis. 
Mount Apo, 1,500 m. s. m., Copeland 1474; San Ramon, Mindanao, Copeland 
1766, forma minor, aliter non diversa. 
DAVALLODES Copeland, genus nov. 
(Microlepia § Davallodes Copel. in Polypodiacese of the Philippines, 1905, 
p. 55.) 
Genus Davalliearum, stipitibus articulatis, rhizomate pilis vestito. 
The only hitherto known species of this genus was first described as a 
Leucostegia, but afterward transferred to Microlepia because of the form of the 
indusium. As a matter of fact, the genus has no indusial character which will 
constantly distinguish it from either Leucostegia or Microlepia. In one species, 
the indusia may be fastened only across the very broad base; in another they are 
the narrowest known to me in any Davalliaceous fern, and fastened the whole 
length of the almost parallel sides. In spite of this diversity of sori, the genus 
is a very natural one. All three of the species I now know are practically 
identical in the appearance of their stout, greenish rhizomes, clothed with stiff, 
bristly, dark hairs with small, peltate bases, and in the remote, broadly 
lanceolate, finely pubescent, exceedingly thin, pinnate fronds, with the pinnte 
deeply and closely pinnatifid, and their segments incised into very sharp 
secondary segments. 
Davallodes is apparently related to both Microlepia and Leucostegia, having 
the jointed stipes of the latter, and the rhizome clothed with hairs as in the 
former. It is known from the Philippines, Celebes, and Borneo. 
Sorus broader than long, attached by the base.. D. gymnocarpum 
Indusium half-cup-shaped, attached by sides D. hirsutum 
Indusium narrowly half-cylindrical.— D. grammatosorum 
Davallodes hirsutum (J. Sm.) Copeland. (Leucostegia J. Sm. nomen; 
Microlepia Presl, Epim. Bot. 1849, p. 97. Davallia ciliata Hooker, Sp. Eil. 1, 
p. 184, Plate 60 A; Microlepia Copel. 1. c.) This species is founded on a Luzon 
plant of Cuming’s collection, which I have not seen. Elmer’s No. 9028, from 
Mount Banajao and Matthew s. n. from Mount Maquiling are quite typical. A 
single frond of my collection, from Bagnen, Lepanto-Bontoc, alt. 1,800 meters, 
differs from Hooker’s figure in being more lax in habit, with the pubescence less 
evidently confined to the veins. The indusia are subglabrescent. My collections 
from near Mount Apo, Mindanao, nos. 1273, 1481, are much less pubescent, the 
indusia being almost all glabrous. In other respects these plants agree with 
the published descriptions and figures. The stipe is 10 centimeters, more or less,
