Pandanus tectorius Sol. var. surigaensis Martelli var. nov. 
Syncarpium 16 cm longum, 13 cm latum, globoso-ellipticum. Phal- 
anges numerosae, parvae, 4-5 cm longae, 2 - 2.5 cm latae, obpyramidatae, 
basi angustatae, acute angulosae, in syncarpio usque ad medium coalitae, 
caeterum divaricatae ; loculis 4-9, saepissime 6-8, parvis, prominentibus, 
pyramidatis; sulcis inter locular ilms profundis.

This is an intermediate form between the variety sinensis and the form of 
the variety Douglasii described above. It seems indeed to have more affinity with 
the latter than with the former. It is distinguished from the var. sinensis by 
its more elliptic syncarp, its longer phalanges with their pyramidal part more 
slender and more elongate, 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 
another, rather shorter and less thick. It is distinguished from the variety 
Douglasii forma philippinensis 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.

1 am doubtful, in consequence of deficient specimens, whether Pandanus cau- 
datus Merrill be a distinct species, or whether it be a variety or form of -the 
Pandanus exaltatus 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 1904, 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 Linnaei, Mr. Merrill himself later recognized in his Pandanus arayat- 
ensis the Pandanus collected by Blanco on Mount Tala and named exaltatus by 
Blanco, which name, by right of priority, I think it best to maintain. I am 
unable to distinguish Pandanus banahaensis Elmer from Pandanus exaltatus 
Blanco.
