Semerara, Merrill JflJfO, July, 1905, in open grass lands along borders of 
thickets but near the sea. 
Gaudichaud’s type phalanges are preserved in the Botanical Museum at Paris, 
doubtfully labeled “India;” but I do not think Pandanus Linnaei to be at all an 
Indian plant, and rightly Sir Joseph Hooker, in his “Flora of British India,” 
6: 408, says of it, “Nothing is known of its origin.” Apparently it must be 
considered as a Papuan species which extends to the Philippines, because Dr. 
Beccari brought it from the Key Islands, and in the Ivew Herbarium there is 
a specimen from the Aru Islands, collected by Mr. Moseley of the Challenger 
Expedition. I have also received the fruits of this Pandanus, together with other 
species closely allied to it, from Peru Island, one of the Gilbert Group. 
Professor Warburg, in Engler’s Pflanzenreich, 3: 46, reduces Pandanus Linnaei 
Gaud, to Pandanus tectorius Sol., while Count Solms-Laubach in Linnaea 42 
(1878) 07, only says of it: “CJonferas Pandanum fascicularem Lin.” (=/’. 
tectorius Sol.) ; but I think it better to consider it as a distinct species. 
Mr. Merrill named the above specimen from Semerara Island Pandanus 
exaltatus Blanco, but in his paper on the identification of Blanco’s species 3 
writes of P. exaltatus: “Erroneously reduced by Villar to P. fascicularis Linn. 
Blanco evidently includes two species in his description, one form growing in the 
mountains, the other at the seashore ; the latter is certainly Pandanus tectorius 
Sol., what the former is, can not be determined from Blanco’s description;” and 
later in a manuscript note which accompanies his herbarium specimen no. 4140, 
Mr. Merrill says: “From Blanco’s description I am confident that he included two 
sjiecies in Pandanus exaltatus, one from the mountains and one from the seashore. 
The one from the mountains is undoubtedly the species I have described as 
Pandanus arayatensis, and 1 am confident that the present no. 4140, represents 
the other form ; I believe it advisable to consider this form as the representative 
of Blanco’s species.” 
Blanco’s description, however, does not appear to me to include two species, 
but only one, that from Mount Tala, which, I agree with Mr. Merrill, is the same 
as Pandanus arayatensis. Blanco speaks incidentally in the note, not in the 
description, of another Pandanus, growing in Laguna, and of this he says: “Hojas 
" " * cocidas en agua hacen con ellas unos petates gruesos llamados bangcoan 
los Tndios de Tala, asi eomo los de La Laguna con su Pangdan Sabotan que es tan 
semejante a este, que tal vez son una misma cosa.” It does not seem to me at all 
probable that the species from Laguna can be the same as that of the mountains, 
and as Blanco does not indicate any distinctive characters for the Pandanus from 
Laguna, I do not consider that the name of P. exaltatus was applied by Blanco 
to two species. However, the Pandanus collected by Mr. Merrill no. 4140, Seme- 
rara Island, is certainly to be referred to P. Linnaei, which in my opinion is 
distinct from P. tectorius Sol., and also different from P. exaltatus Blanco.

This is the moslj diffuse and polymorphic species of the genus, and is the only 
one extending over both the Indo-Malayan and Polynesian regions. It is probable 
that its wide geographical distribution may be explained by its growing on the
