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 lierbarium under the name of Pandanus ruhescens with the lal)el: 
"Philippines, Avril, legit Porte, 1860, cult, in Horto Bot. Paris, 18G8." From the 
structure and disposition of its male flowers, it may he placed, I tliink, in tlie 
section Byl-ia. Having asked Mr. Merrill for some information nl>out the proh- 
i\!>le habitat of Pandanus malaten.'iis, I received an answer from liini that in 
Blanco's type locality Malate, a suburb of Manila, he has met witli no Pandiinus 
except P. iectorius Sol., which doe.s not correspond at all with Bhinco's descrijitiou 
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 Manibi, and it is probable that 
many species of plants which were growing there sixty or more years ago have 
no\^- disappeared, Pandnnm mafotmsis may be one of them. 
§ ACROSTIGMA. 
(22) Pandanus Merrillii Warb. in Perkins, Fragm. Fl. Philip. (1904) 50. 
Palawan (Paragua), San Antonio Bay, Merrill 8.',0, February, 1903, on dry 
slopes in forests at 300-500 m alt.; Puerto Princesa, Bur. Soi. 232 Bennejos, 
December, 1905. 
The type specimen of P. MerHllH is no. 840, collected at San Autoiim 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 smootli or 
very sli-hlly spiuulose near its base. The raceme however is 25 cm in length, 
composed of .yncavps, which as well as tlie drupes perfectly agree with those 
of the type specimen"

Mr Loher sent to Kew as no. 1571 a specimen of this Pandanus, collected by 
him-'lf at Limutan, Luzon. He supposed it to be P<mdanus foetidns 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 Copelandn 
Merrill, the indicated differential characteristics being too variable and not very 
important. 1 have in my collection some large splendid specimens of P. muricatus, 
which I can not differentiate from Pandanus Copelandii Merrill. Some of them
