PLAGIOGYRIA Mettenius. 



Plagiogyria nana sp. nov. 



Plagiogyria gregis P. glaucae Mett. qua statura reducta, pinnis rigidis 

 confertis obtusis conspicue differt. Stipite frondis sterilis 3-5 cm alto, 

 frondis fcrtilis circiter 15 cm, aerophoris paucis; fronde sterile 10-13 cm 

 alta, 5-6 cm lata; pinnis approximatis vol 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.

 & Zschokke, common in grass lands, altitude 2,860 m, Copeland P. P. E. 11.). 



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 Enuni. (1828) 129.

 & Zschokke, mixed with plants of the mossy forest, altitude probably 2,800 in. 

 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-dissectum Zoll. 8y«t. Very.. (1854) 38, 48. 



P. gedcanum 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 curran ii sp. nov. 



Species P. tenuilori Kze., et P. dolichoptero Copel. affinis, fronde 

 pseudo-f urcata ; rhizomate 3 mm crasso, paleis atro-fuscis angustatis 3 mm 

 longis vestito; stipite obscure articulato, undo, circiter 1 cm alto vel usque 

 ad furcam 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, acuminatis, omnino glabra, herbacea, 

 venatione gracile, inconspicua ; soris multis, irregularibus, saepius elonga- 

 tis, minutis. 



Luzon, Province of Benguet, Mosquito Creek, For. Bur. 15128 Curran, altitude 

 2,000 m. 



This is decidedly more slender throughout than Polypodium dolichoptcrnm. 

 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.
