Blanco’s Pteris signata=Polypodium signatum is very im-
perfectly described, and the species has been considered a very
doubtful one. Fernandez-Villar reduced it to Polypodium albido-
squamatum Blume, which is a species of the mossy forests, while
Blanco definitely states that his specimens were from Manda-
loyon, near Manila, a region where Polypodium albido-squamatum
does hot and cannot grow, Blanco’s description, so far as it
gees, applies perfectly to Nephrolepis biserrata Schott which is
abundant about Manila, many specimens of which present the
white dots on the upper surface Mentioned by him. Blanco’s
Poly podium serratum is certainly the same species, a form with-
out the manifest white dots on the upper surface.
Illustrative specimen from Mandaloyon, Rizal Province, Luzon,
October, 1914 (Merrill: Species BUmcoanae No. 153).
