under the name of F. cumingiana, and also a second Philippine species, 
F. sphaerocephala, in the Botany of the A^yage of tlic Bonite, Atlas, 
1843. In 1883, Naves in the Novissinia Appendix to the tliird edition 
of Blanco's Flora do Filipinas, 285, 28G, enumerates four species, which 
are all, with the possible exception of F. luzonensis, admitted on 
erroneous identifications, and can be ignored. He reduced Tillandsia 
pseudo-ananas Blanco to Freycinetia insignis Blume, but this is a manifest 
error, as an examination of Blanco's description shows conclusively that 
Tillandsia psetido-ananas can not be a Freycinetia, but is probably a 
Pandanus, and possibly the same as F. copelandii Merr. Blanco did not 
consider any species of Freycinetia in his Flora de Filipinas. 
Having recently had an opportunity to examine the types or authentic 
material of all tlie Philippine species considered by Warburg, in the 
herbaria at Ivew and Berlin, it became evident that a certain number of 
recently described forms were invalid, three of the species described l)y 
Mr. Elmer, and one by myself.- In justice to Mr. Elmer, however, ft 
is manifest that the determination of two of Ins species as new, F. 
Iuchanc7isis and F. confusa, was due to errors in AVarburg's monograph, 
the former being identical with F. ferox AVarb., the leaves of the type of 
which are about 1 m long but described as 30 cm long, the latter being 
the same as F. vidalii Hemsl. The affinity of the latter was recognized 
by Mr. Elmer, but Hemsley's species was placed by Warburg in the 
wrong section of the genus, the type being a very immature specimen. 
^ In view of the fact that a recent paper has been' published on Philip- 
pine Pandamis, it has been thought ad\nsable to prepare a list of the 
known species of the other large genus in the family, Freycinetia, giving 
also a provisional key to the species. Twenty-four species a,re recognized, 
all of which are endemic in the Philippines, so far as is known, giving 
the Archipelago a far greater known immber of species than any other 
geographical region in which the genus is found. Luzon alone has 
eighteen species, while the region about Mount Banajao, Province of 
Tayabas, Luzon, is remarkable in having no less than eleven species of 
the genus, more than are known from any single island in the Malayan 
region; New Guinea and the Malay Peninsula coming first with but 
eight species, Celebes next with seven, Java with six, Borneo and New 
Caledonia with four each, Sumatra with three, and various other islands 
with one or two species each. The above distribution list is based largely 
on Warburg's monograph, and the number of species actually known 
from some of the above islands may be larger than the figures given, 
while undoubtedly a great many undeseribed forms remain to be col- 
lected.
