better to Pteris vittata Linn. than to any other species known 
tome. This form appears in herbaria as Pteris longifolia Linn., 
but Hieronymus, Beitrage zur Kenntnis der Gattung Pteris, 
I. Uber Pteris longifolia L. und verwandte Arten. Hedwigia 54 
(1913) 283-294, has shown that Pteris longifolia Linn. is a 
species confined to tropical America, and that P. vitiata Linn. 
is the proper name for the very common and widely distributed 
form in the Old World.

This species was reduced by Fernandez-Villar to Lindsaya 
retusa Mitt. = Odontosoria retusa J. Sm., a species that not only 
does not grow in the vicinity of Manila (Blanco’s material was 
from Mandaloyan), but also a fern to which Blanco’s descrip- 
tion does not at all apply. The statement “Las fructificaciones 
en linea continua en las margines redobladas de las pinas’”’ defi- 
nitely places Blanco’s plant in the genus Pteris; but three species 
of the genus grow naturally in the vicinity of Manila, and 
Blanco’s description applies to the form distributed herewith 
better than to any of the others, although it does not agree in 
all particulars. This form has generally been determined as 
Pteris quadriaurita Retz., but Hieronymus, Hedwigia 55 (1914) 
325-375, has shown that Pteris quadriaurita Retz. is confined 
to Ceylon, and considers that the “collective species” of the 
older authors includes numerous distinct species. The form here 
considered appears to be Pteris flava Goldem., but I cannot dis- 
tinguish clearly between P. flava Goldem. and P. glaucovirens 
Goldem. from the data given by Hieronymus who cites Cuming 
79 under both.
