del mar, y en los bosques.” The seacoast form is, without the 
slightest doubt, a form of P. tectorius Sol.; the forest form, true 
P. exaltatus Blanco as described by him. It has been described 
by me as Pandanus arayatensis; by Mr. Elmer as P. banahaen- 
sis; and by Dr. Martelli as P. vidalii, for I consider the type of 
P. vidalii Mart. to be only a form of P. exaltatus Blanco with 
juvenile fruits. Vidal’s figure, mentioned by Martelli, is an 
entirely different species, and represents the common beach form 
of Pandanus tectorius Sol. that is abundant along the shores 
of Manila Bay. Pandanus tectorius, at full maturity, develops 
a thick, soft, fleshy, edible pulp about the lower part of each 
drupe, and this mature form Vidal figures; this pulp sometimes 
persists in the dried drupes'as a zone or collar, as in the form 
of P. tectorius described by Martelli as P. coronatus. 
Illustrative specimen from Sablan, Benguet Subprovince, 
Luzon, November, 1910, slightly different from the form grow- 
ing in Bulacan, Rizal, Bataan, and Laguna Provinces, Luzon, 
Blanco’s type being from the mountain back of Tala, Bulacan 
Province, Luzon (Merrill: Species Blancoanae No. 421).

This species is very abundant along the seashore throughout 
the Philippines, presenting but slight variation in its fruit 
characters so far as Philippine material is concerned. It usually 
forms dense thickets immediately back of the beach. As 
Pandanus spiralis R. Br. is reduced to P. tectorius Sol., I have 
assumed the Philippine plant described by Blanco to be a form 
of Robert Brown’s species, althongh probably not exactly the same 
in all details. Pandanus spiralis Blanco, non R. Br., is the whole 
basis of Pandanus blancoi Kunth, which hence becomes a syn- 
onym of Pandanus tectorius Sol. Pandanus malatensis Blanco 
has been retained by Martelli as a distinct species, but Blanco’s 
description is manifestly that of the staminate inflorescence of 
Pandanus tectorius Sol. Malate is a part of the City of Manila, 
and only cultivated pandans, such as P. veitchii and perhaps P. 
sanderi are now to be found in Malate. In Blanco’s time, when 
Malate was still a village, the common seacoast pandan was 
undoubtedly abundant along the Malate beach, now entirely 
altered by streets and buildings, as it is still very abundant along 
the Pasay beach immediately south of Malate; Pandanus tec-
