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 blancoi A. DC., was based on Q. glabra Blanco, 
non Thunb., but Q. ovalis of the second edition of the Flora de Filipinas is 
manifestly Q. glabra of the 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. Vidal 14 has attempted to hold Quer-
