VITTATA Linn. (P. longifolia Auct., non Linn.).
Adiantum lancea Blanco was reduced by Fernandez-Villar to
Lindsaya ensifolia Sw.=Schizoloma ensifolium J. Sm., a species
that does not occur near Manila and one which is very rare in
the Philippines. The description is very poor, but so far as it
goes agrees fairly well with Pteris vittata Linn, which is common
in and about Manila and which is widely distributed in the Phil-
ippines ; Blanco’s specimens were "from Mandaloyon, a suburb
of Manila. Pteris tnchomanoides Blanco was reduced by F.-
Villar to Nephrolepis racemosa Moore, but from Blanco’s im-
perfect description it cannot possibly belong in Nephrolepis,
but is unquestionably Pteris vittata Linn. Pteris grandifolia
Blanco was reduced by F.-Villar to P. opaca J. Sm., which is
unquestionably an erroneous disposition of it. The name taga-
has, one of these cited by Blanco, is now used in parts of Cavite
Province, Luzon, to designate a species of Dryopteris of the D.
parasitica group. Blanco’s short description, however, applies
better to Pteris vittata Linn, than to any other species known
to me. This form appears in herbaria as Pteris longifolia Linn.,
but Hieronymus, Beiträge zur Kenntnis der Gattung Pteris,
I. über Pteris longifolia L. und verwandte Arten, ffedwigia 54
(1=913) 283-294, has shown that Pteris longifolia Linn/is a
species confined to tropical America, and that P. vittata Linn,
is the proper name for the very common and widely distributed
form in the Old Worl$.
