Luzon, Manila (Malate) fide Blanco; without locality, living plant flowering 
in the Paris Botanical Garden in 1808, collected by Porte (in Herb. Paris). 
Blanco’s description of Pandanus malatensis is very short and obscure, but 
it does not disagree with the male specimens here described which are preserved 
in the Paris herbarium under the name of Pandanus rubescens with the label: 
“Philippines, Avril, legit Porte, 1860, cult, in Horto Bot. Paris, 1868.” From the 
structure and disposition of its male flowers, it may be placed, I think, in the 
section Rylcia. Having asked Mr. Merrill for some information about the prob- 
able habitat of Pandanus malatensis, I received an answer from him that in 
Blanco’s type locality Malate, a suburb of Manila, he has met with no Pandanus 
except P. tectorius Sol., which does not correspond at all with Blanco’s description 
of Pandanus malatensis. The fact that no other species of Pandanus is now 
found in Malate proves very little, because it is certain that since Blanco’s time 
many changes have occurred in the districts near Manila, and it is probable that 
many species of plants which were growing there sixty or more years ago have 
mow disappeared. Pandanus malatensis may be one of them. 
§ ACROSTIGMA. 
(22) Pandanus Merrill ii Warb. in Perkins, Fragrn. FI. Philip. (1604) 50. 
Palawan (Paragua), San Antonio Bay, Merrill 81/0, February, 1903, on dry 
slopes in forests at 300-500 m alt. ; Puerto Princesa, Bur. Pci. 232 Bermejos, 
December, 1905. 
The type specimen of P. Merrillii is no. 840, collected at San Antonio Bay in 
Palawan; the others gathered in the same island at Puerto Princesa appear to 
be different, since they carry only a terminal shoot of young leaves which are 
smaller, 70-80 cm in length, and 2-2.5 cm in width, with the midrib smooth or 
very slightly spinulose near its base. The raceme however is 25 cm in length, 
composed of 6 syncarps, which as well as the drupes perfectly agree with those 
of the type specimen.

For. Bur. SlfSS Ahern’s collector; Limutan, Loher 1571 (in Herb. Kew). 
Mr. Loher sent to Kew as no. 1571 a specimen of this Pandanus, collected by 
himself at Limutan, Luzon. He supposed it to be Pandanus foetidus Roxb. 
It consists of an unripe syncarp and two leaves ; one of these is broader than the 
other and apparently belongs to P. Copelandii Merrill; the narrower and longer 
one is apparently that of a different species. It is impossible, I believe, to 
separate specifically Elmer’s Pandanus muricatus from Pandanus Copelandii 
Merrill, the indicated differential characteristics being too variable and not very 
important. I have in my collection some large splendid specimens of P. nnlricatus, 
which I can not differentiate from Pandanus Copelandii Merrill. Some of them
