NovEMBER 15, 1910] Tue Ferns or Mount Apo . 841 
This is a very small form of the same species, its stature 
being presumably due to the unusual illumination it receives 
by growing on dead limbs. I have seen dwarf forms of several 
species caused in this way. 
Northward to Mindoro. 
Malaya. 
Polypodium nutans BI, 
Mixed with P. mollicomum, Mt. Apo, alt. 1800 m., 
No. 11474.” A few plants, quite distinct, and exactly like 
Javan specimens. 
New to the Philippines. 
Malaya, New Caledonia. 
Polypodium tenuisectum Bl. 
In mossy forest, Mt. Apo, alt. 1800 m., Copeland 1599. 
High summits northward to Pinatubo. 
Malaya, Samoa. 
Polypodium pulcherrimum Copel. spec. nova. 
Eupolypodium bipinnatum glaberrimum; rhizomate et ad 
terram et ad arbores late repente, nigro, 1 mm. crasso, paleis 
ovatis fulvis 2-8 mm. longis vestito; stipitibus inter se ca. 
1 em. distantibus, haud articulatis, paleis paucis minu- 
tis caducis vestitis vel ab initio glabris, 2-5 cm. altis; 
fronde usque ad 35 cm. alta, 7 cm. lata, in caudam linearem 
piunatam contracta, aliter bipinnata, rhachi atro, angustissime 
viride-alato; pinnis contiguis, horizontalibus; pinnulis infra 
mediam frondem sterilibus, majoribus plusquam 5 mm. longis, 
0.3 mm. latis, inter se ca. 1.5 mm. remotis, ala decurrente 
connexis vel liberis; pinnulis fertilibus acutissimis, in partem 
medialem dilatatam unisoriatis. 
Mt. Calelan, alt. 2500 m., No. 11355. ‘‘Libagod-ta 
lomat” (Fern in the moss.) 
Sterile specimens of this fern would surely be mistaken 
in the field for Trichomanes. In fruit it strongly resembles 
P. Yoderi, but differs from that and from all other related
