This species is well characterized by its large fruits, its acorns being consider- 

 ably larger than those of any other species known from the Philippines.

A very characteristic species, entirely glabrous or nearly so, with shining 

 coriaceous leaves. Blanco's specific name ovalis is the earliest valid one available, 

 and is here retained. Quercus hlancoi A. DC, was based on Q. glahra Blanco, 

 non Thunb., but <}. oralis of the second edition of the Flora de Filipinas is 

 manifestly Q. glahra of tlie first edition, Blanco having recognized his own 

 error in referring Philippine material to Thunberg's species, simply proposed the 

 new name ovalis, but did not indicate this. VidaP^ has attempted to hold Qucr-
