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 Quercus celebica Miq. It does not, however, appear to 

 be very closely allied to Miquel's species, which was placed by DeCandolle in the 

 section Cyclohalanus, and by King in the section Pasania. I am of the opinion 

 that the present species is a Cyclohalanus, although the bracts of the upper laminae 

 are nearly free. It differs decidedly from Quercus celebica 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 Zamboanga in dipterocarp forests at an altitude of 

 from 20 to 30 m above the sea.
