PHILIPPINE SPECIES OF PANDANUS. 
63 
A leaf specimen only, bearing the no. 2700 in the Herbarium at Manila was 
identified by Merrill as Pandanus Sabot an Blanco, and of this he writes: “This 
is a cultivated form which I have never seen in fruit. It is perhaps a form of 
P. tectorius Sol. The native collector, Ramos, in whom I have considerable 
confidence, insists that this is the only species which is called ‘Sabotan,’ and 
that it is not found in the forests but only cultivated about houses and in towns. 
He also says that the leaves are used by the natives for making mats, etc., which 
also agrees with Blanco’s note.” In my opinion, because of the shape, dimensions 
and characteristic position of the teeth, this specimen is Pandanus tectorius var. 
sinensis Warb. 
It seems to me that Pandanus Sabotan Blanco is a quite different species, and 
I judge so from Blanco’s description, where it is said that the intermediate portion 
of the midrib is toothless and the secondary or lateral foldings toward the apex 
(that is to say, on the upper surface) are toothed, so that toward the base of 
the leaf there are three lines of teeth, but toward the apex the lines are four. 
This characteristic does not exist in the leaf of the specimen no. 2700 mentioned 
above and I have never seen a form of Pandanus tectorius Sol. with the secondary 
folding toothed. Naves in Blanco’s PI. Filip, ed. 3, 4: 285, thought that 
Pandanus Sabotan Blanco was the same as Pandanus dubius Spreng. 1 believe 
this opinion also erroneous and therefore consider that P. Sabotan Blanco is a 
species not yet identified. 
Pandanus tectorius Sol., var. Douglasii Martelli, forma philippinensis. 
Pandanus Douglasii Gaudich. Bot. Voy. Bonite t. 22, f. 16. 
Ereeto-p rostratus (Copeland). Folia 1.5 m longa, 3.5 cm lata, longe 
attenuato-aenminata, clentibus marginalibus basin versus approximatis, 
latiusculis, subulatis, erecto-patentibus, vix incurvatis ; iota costa media 
spinis subdistantibus, subulatis armata, quarum basilaribus validiusculis, 
brevissimis, basi inflatis, imis tantum retroflexis. Syncarpii phalanges 
in parte basilari breviter (sive tantum in earum quartam inferiorem 
partem) connatae, caeterum liberae et divaricatae, 4-4.5 cm longae, 
2 — 2.5 cm latae, acute angulosae, obscure pentagonae, in dimidia 
superiori parte subcylindraceae, caeterum basin versus attenuato- 
obpyramidatae, ipsa basi angusta, vertice piano; loculis parvis, 6-8, 
prominentibus, pyramidatis, suleis interlocularibus profundis. 
Mindanao, District of Davao, Malalag, Copeland 612, 1904, common along the 
seashore. 
Gaudichaud figured Pandanus Douglasii from some phalanges collected in the 
Hawaiian Islands during the voyage of the Bonite, and the specimens are 
preserved in the carpological collection of the Botanical Museum of Paris with 
many others of Gaudicliaud’s type fruits. 
Prof. Warburg in Engler’s Pflanzenreich, 3: 46, places Pandanus Douglasii 
among the numerous synonyms of Pandanus tectorius Sol., and does not consider 
it even as a variety, but I am of the opinion that if it is right to unite it 
specifically with Pandanus tectorius Sol., it should be distinguished as a variety. 
I have not yet received from the Hawaiian Islands some promised complete 
specimens of typical Pandanus Douglasii, and therefore I am not yet able to 
state if the leaves and whole synearp of the Hawaiian plant exactly coincide with 
the corresponding parts of the Philippine form, the identification of the latter 
having been made by the likeness of the phalanges.
