This is an internietliate form between the variety sinctisis and the form of 
the variety Doufjlasii described ahove. It seems indeed to have more affinity with 
the latter than with tlie former. It is distinguiHhed from the var. sinensis by 
its more elliptic syncarp, its longer phalanges with tlieir pyramidal jjart more 
slender and more elon,i:ate, smaller locules which are more pyramidal and more 
separated from one another by deep furrows. The shape of the teeth on the 
margins of the leaves is almost the same, but the teeth are a little closer to one 
anot^ier, rather shorter and less thick. It is distinguished from the variety 
Douylasii forina pfiilippinCHsis by having the phalanges separated from one 
another only in their upper half, not swollen at all in the middle, but straight and 
acutely obpyramidal.

I am doubtful, in consequence of deficient specimens, whether PowJanus Cau- 
da f us :Merrill be a distinct species, or whether it he a variety or form of the 
Pandanus exaJtatus Blanco.

Mr. Loher, some years ago, collected on Mount Arayat a Pandanus and sent 
it to Kew, under the name of Pandanus polycephalus. Afterwards, in 1004, Mr. 
Merrill ascending the same mountain found the same form and believing it to 
be an undescribed species, named it Pandanus arayatensis. As noted above under 
Pandanus Linnuvi, Mr. Merrill himself later recognized in his Pandanus arayat- 
ensis the Pandanus collected by Blanco on Mount Tala and named exaltatus by 
Blanco, which na^ne, bj' right of priority, I think it best to mnintain. I am 
unable to distinguish Pandanus hanahaensis Khner from Pandanus exaltatus 
Blanco.
