obsoletis; cupulis 2 cm diametro, circiter 1.5 cm altis, truncatis, 

 utrinque dense pubescentibus, zonis circiter 10, contiguis, den- 

 tibus numerosis, confertis, 1.5 ad 2 mm longis; glans oblongo- 

 ovoideis, glabris, nitidis, 2.5 cm longis et 1.7 cm diametro. 



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 castaneous- 

 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. Glans 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.
