Polillo' almost defies tabulation, but the following summary will indicate 
its nature. 
Endemic 14 
Not endemic, but with no other Philippine locality 4 
Tayabas only 14 
Tayabas, and the Visayas, or Mindoro, or Mindanao 5 
Tayabas, and two or more of preceding 8 
Luzon, south of Tayabas, only 2 
Luzon, south of Tayabas, and Mindanao 1

Laguna and Rizal, each 1 
Tayabas and Laguna or Rizal, or all three 5 
Tayabas and Laguna or Rizal, or all, with further southward 
extension 8 
Laguna or Rizal, not Tayabas, but farther south 12 
Cagayan and Isabela, each 1

Mindoro or farther south 6 
None of these are yet known from western Luzon, and they comprise 
all the species whose distribution was sufficiently restricted to be con- 
sidered worthy of mention, except 12. Two of the exceptions are known 
from Polillo and Bataan only, Luisia foxworthii Ames and Dysoxylum 
altissimum Merr. : in neither case is the identification quite certain. 
Of the remaining 10, locations are known- on the western slope, and 
with one exception on other parts of the eastern besides Polillo. Pour 
of these are widely distributed on the eastern slope, but on the western 
known only from eastern Bulacan, three of the four are dipterocarps, 
a group which has been very carefully investigated. Moreover, Ardisia 
pirifolia is at best very doubtfully distinct from a species of very wide 
Philippine distribution, and the collections identified as Diospyros nitida 
from Polillo, the only known east coast station, are not typical. Ischae- 
mum intermedium and Procris philippinensis will probably prove to have 
a wide but local distribution, while Astronia williamsii and Jasminum 
macrocarpum appear to range across central Luzon.
