PLAGIOGYRI A Mettenius. 
Plagiogyria nana sp. nov. 
Plagiogyria gregis P. glaucae Mett. qua statura reducta, pinnis rigidis 
confertis obtusis conspicue differ!. Stipite frondis sterilis 3-5 cm alto, 
frondis fertilis circiter 15 cm, aerophoris paucis; fronde sterile 10-13 cm 
alta, 5-6 cm lata; pinnis approximate vel infimis paullo remotis, fere 
omnibus liberis, sessilibus, circiter 6 mm latis, obtusis, minute serrulatis, 
rigide coriaceis, infra glaucis; fronde fertile circiter 10 cm alta, sat con- 
densata, pinnis 25-35 mm longis, linearibus, falcatis. 
Luzon, Province of Benguet, Mount Pulog, For. Bur. 16306 Curran, Merritt, 
£ Zschokke, common in grass lands, altitude 2,850 m, Copeland P. P. E. 113. 
This is conceivably a form of P. glauca, due to the very unusual environment, 
but is distinct in various respects beside the stature. Specimens growing in 
brush are of course decidedly less dwarfed, but they are still far from typical 
P. glauca. 
POLYPODIUM Linn. 
Polypodium subpinnatifidum Blume Enum. (1828) 129. 
Luzon, Province of Benguet, Mount Pulog, For, Bur. 16293 Curran, Merritt, 
& Zschokke, mixed with plants of the mossy forest, altitude probably 2,800 m, 
Copeland. 
The stipes are less hairy than figured by Blume, and in one specimen are 5 
cm long, but the .identification is unmistakable. The plant is already known 
from Java and Perak; new to the Philippines. 
Polypodium subsecundo-d issectum Zoll. Syst. Verz. (1854) 38, 48. 
P. gedeanum Racib. Pterid. Buit. (1898) 96. 
Luzon, Province of Laguna, Mount Banajao, Copeland 2136, found once on 
a mossy trunk, altitude 2,250 m. 
Known from Java and New Caledonia; new to the Philippines. 
This has been described as a relative of Polypodium minutum and P. sub- 
falcatum. It is really nearly related to P. tenuisectum Bl., and is a link, 
hitherto needed, between the few species with dissected fronds and the body of 
the genus. The stipes are not articulate. 
Polypodium curranii sp. nov. 
Species P. tennilori Kze., et P. dolichoptero Copel. affinis, fronde 
psendo-furcata ; rhizomate 3 mm crasso, paleis atro-fuscis angustatis 3 mm 
longis vestito ; stipite obscure articulato, nudo, circiter 1 cm alto vel usque 
ad fur cam infimam frondis circiter 15 cm alto alato, ala sursum 2-3 mm 
lata; fronde furcato-pinnata, ramis paucis, ultimis 5-15 cm longis plus 
minus divergentibus 3-7 cm latis, aeuminatis, omnino glabra, herbacea, 
venatione gracile, inconspicua ; soris multis, irregularibus, saepius elonga- 
tis, minutis. 
Luzon, Province of Benguet, Mosquito Creek, For. Bur. 15728 Curran, altitude 
2,000 m. 
This is decidedly more slender throughout than Polypodium dolichopterum, 
and the lateral segments are so strongly developed that the lower ones almost 
rival the main axis, and many fronds look monopodial rather than pinnatifid. 
P. tenuilore has a simple and entire frond, but is like this group in texture, 
venation, and sori.
