utrinque dense pubescentibus, zonis circiter 10, contiguis, den- 
tibus numerosis, confertis, 1.5 ad 2 mm longis; glans oblongo-

A tree about 20 m high, the branchlets and lower surface 
of the leaves minutely brownish puberulent or pubescent. 
Branches subterete, smooth, subolivaceous. Leaves oblong, 
coriaceous, 9 to 14 cm long, 3.5 to 6 cm wide, entire, base acute, 
apex slenderly acuminate, the acumen about 1 cm long, obtuse, 
the upper surface glabrous, smooth, shining, brownish when 
dry, or when young slightly puberulent, the lower surface of 
the same color or slightly paler, brownish-pubescent with very 
short hairs; lateral nerves about 9 on each side of the midrib, 
prominent, curved, obscurely anastomosing, the reticulations 
slender, obscure, often nearly obsolete ; petioles eastaneous- 
pubescent, about 5 mm long. Infructescence a simple spike 
about 10 cm long, the rachis rather stout, pubescent, each 
bearing but few fruits. Cups cupshaped, 2 cm in diameter, 
about 1.5 cm high, truncate, densely pubescent with pale- 
brownish hairs on both surfaces, sessile, the zones about 10, 
contiguous, the teeth numerous, crowded, oblong, acuminate, 1.5 
to 2 cm long. Gians oblong-ovoid, glabrous, shining, brown 
when dry, 2.5 cm long, 1.7 cm in diameter, apiculate, the lower 
7 mm included within the cup.

September 19, 1917, on forested ridges, altitude 300 meters and above, 
locally known as ulayan. 
In vegetative characters this species closely resembles Quercus lipacon 
Elm. of Mindanao, but is entirely different in its fruit characters. The 
cups strongly resemble those of Quercus jordanae Laguna, but the present 
species is not otherwise closely allied to that species.
