This species was previously identified erroneously by me as Q. philippinensis 
A. DC, to which it is not at all closely allied, and later the same specimen was 
referred by Von Seemen to Querciis celehica Miq. It does not, however, appear to 
be very closely allied to Miquel's species, which was placed by DeCandolle in the 
section Gyclohalanus, and by King in the section Pasania. I am of the opinion 
that the present species is a CyclohaJanus, although the bracts of the upper laminse 
are nearly free. It dilTurs decidedly from Quercus celehica in being more pubes- 
cent, with larger fruits and very much more acuminate leaves. This species 
» grows at lower altitudes than any other species known from the Philippines, 
occurring in the District of Zamboaiiga in dipterocarp forests at an altitude of 
from 20 to 30 m above tlie sea.
