POLYPODIUM SUBRETICULATUM sp. nov. 
Eupolypodium, rhizomate brevi-repente, paleis laete brunneis 
ovato-lanceolatis dense vestito ; stipitibus proximis, 1-2 cm altis, 
validis, setis purpureo-castaneis ca. 2 mm longis vestitis ; fronde 
usque ad 25 cm alta et 12 mm lata, utrinque sensim attenuata, 
integra vel subintegra, coriacea, pilis fere nigris sparsis vestita 
vel in vetustate calva; venis furcatis venulis liberis, vel 2-4 
ramos emittentibus et venulis hie illuc haud saepe anastomosan- 
tibus ; soris irregulariter 2-3-seriatis, superficialibus, orbicu- 
laribus vel oblongis.

This suggests P. congeyierum and P. diplosorum Christ, both of which, 
on the more ample fronds, have sori in plural rows or scattered. The oc- 
casional anastomosis of veins is also correlated with the ampleness of the 
entire froud, and is occasionally seen in the various species of the group. 
Loxogramme is a group derived form Eupolypodium with entire fronds; 
its fronds are in general more ample than in any of the parent group, and 
reticulate venation is a fixed character.

An immediate relative of P. subauriculatum Bl., with exceedingly slender 
pinnae, separated by five times their own breadth. A Philippine fern called 
by Christ P. subauriculatum integrum has pinnae almost as narrow, but 
closer together, shorter, entire and thicker. My specimen of P. tenuissimum
