glauco, radicoso, stipitibns solitariis articulatis basi parcis setulis nigris 
praedito aut glabris, tenuibus, stramineis, 6 ad 8 cm. longis sed ob 
laminan longe decurrentem fere usque ad basin alatis, fronde 40 cm. 
longa 18 cm. lata, ovali, longe sensimque decurrente et lobo simplici 
caudato 18 cm. longo terminata, 4 aut 5 lobis later alibps ala costali 
utrinque 13 mm. lata, lobis remotis 10 cm. longis, 1.5 cm. latis acutissime 
caudatis sinubus vastis rotundatis 2 ad 3 cm. latis inter jectis, marginibus 
integris rhachi costisque stramineis manifestis, nervis lateralibus curyatis 
tenuissimis versus marginem evanidis, areas et areolas numerosis oblon- 
gis nervulos furcatis includentibus, soris irregulariter bi- aut triseriatis

ore macula obscura vix impressa notatis, fovea marginata sorali deficiente.

Luzon, Province of Rizal, Bosoboso (1087 Ramos) July, 1906. 
A species near P. phymatodes, but_ distinguished by its long decurrent frond, 
thin and diaphanous texture and small irregular sori which are not immersed 
in pits. 
83. Polypodium palmatum Blume Fil. Jav. 150. 
Copeland 20 credits Polypodium trifidum Don to the Philippines, but as he 
presumes, 1. c., all the specimens from the Archipelago are referable to P. 
palmatum Blume, also those that I have cited previously for P. trifidum. 21 
Typical P. trifidum is an essentially Chinese species which does not extend to 
Japan nor to the Malayan Archipelago. 
84. Polypodium productum n. sp. 
Rhizomate breviter repente radicoso squamis minutis 2 mm. longis 
setaceis sparso, foliis approximate nudis 63 cm. longis in stipitem 
stramineum 10 cm. longum sensim decrescentibus longe et acute acumi- 
natis, medio 1 ad 12. cm. versus apicem 4 mm. latis, costa prominente, 
straminea margine anguste revoluto, nervis occultis, soris 30 ad 50 
utrinque marginalibus impressis versus apicem ultra marginem protrusis 
ovatis 4 mm. longis, 2 ad 3 mm. distantibus. Textura rigide coriacea, 
colore flavovirescente sublucido. 
Mindanao, Province of Zamboanga, San Ramon (1585 Copela/nd ) January, 
1905, alt. 175 m. 
A species related to P. longifolium Mett., which is also found in the Archipelago, 
Palawan (631 Foxworthy) April, 1906, differing from the latter in its firm 
texture, pale color, shining, the fronds narrower and long acuminate at the 
apex, the margins inflexed and the sori much elongated. P. longifolium is 
broadei’, the apex not sharp, the texture less firm, opaque, dark brown when 
dry, the sori often more rounded.
