PTERIDOPHYTA HALCONENSES.

HU MATA Cav. 
Humata lepida (Presl) Moore. 
On rocks at 150 m. alt., along the river (No. 5940), and epiphytic in the ridge 
forest at 1,400 in. alt. (No. 5941). 
Previously known from Samar and Luzon, and also collected on Mount Haleon 
by Merritt, June, 1906, at 1,700 m. alt. (No. 4465). 
DAVALLI A Smith. 
Davallia divaricata Blume. 
Epiphytic in humid forests at 100 m. alt. (No. 5943). 
Previously collected in the Philippines in Luzon and in Mindanao. 
India to Malaya. 
Davallia embolostegia Copel. 
Epiphytic in forests at 900 m. alt. (No. 5942). 
Previously known only from Luzon. 
TAPEINIDIUM (Presl) C. Chr. 
Tapeinidium pinnatum (Cav.) C. Chr. (Microlepia pinnata J. Sm.) . 
Terrestrial in ridge forests at 700 m. alt. (No. 5944), both the typical pinnate 
form and the doubtless more primitive tripinnate form. 
Common throughout the Philippines. 
Malaya, Polynesia. 
SACCOLOMA Kaulf. 
Saccoloma moluccanum (Bl.) Mett. 
Humid forests at 200 m. alt. (No. 5951) a very large form, the stipes nearly 
1 m. tall. 
Luzon, Benguet. 
Malaya to Polynesia. 
DENNSTAEDTIA Bernh. 
Dennstaedtia scandens (Bl.) Moore. 
Scandent in thickets and forests, sometimes 5 m. high, 570 to 1,000 m. alt. (No. 
5953). 
Previously collected in the Philippines in Luzon and Mindanao. 
Malaya to Samoa. 
The material is without any trace of an extrorse indusium and in my opinion 
would better be treated as both Hooker and Smith treated Cuming’s Philippine 
plant 2 as Hypolepis, if Hypolepis were itself a natural genus. Very similar species 
in Hypolepis are already known from South Africa and Tropical America. In the 
latter region, as here, the separation is at present an arbitrary one. If the 
hypolepoid relatives of Dennstaedtia are not included in Dennstaedtia, they should 
receive a new generic name, since the original Hypolepis, H. tenuifolia, seems more 
nearly related to Dryopteris. 
Dennstaedtia scabra (Wall.) Moore. 
On ridges in the mossy forest at 2,100 m. alt. (No. 5950). 
Already known from the Philippines from similar altitudes in northern Luzon, 
and on Mount Apo, Mindanao. 
India to Japan and Celebes.
