A species well eliaracterized by its small coriaceous leaves and small fruits, 
tlie involucres being rather densely cinereous-pubescent. In leaf characters some- 
what similar to Quercus merrillii Von Seem., but the fruits are entirely different. 
§ Cyclobalanus. 
5. Quercus caudatifolia sp. nov. 
Arbor 17 ad 25 m alta; foliis oblongo-Ianccolatis^ 8 ad 14 cm longiSj 
basi aeutis, apice sensim caudato-acuminatis, acuminibus obtusis, supra 
glabris, subius pallidioribus, jimioribus plus minus cinereo-fernigineo- 
puberulis, ncrvis utrinquo circiter 10, subtus distinctis, reticulis subob- 
soletis; glandibus oblongo-conico-oyoideis, pubcrulis, 1.5 ad 2 cm longis, 
8 ad 12 mm diametro; cupulis plus minus einereo- vel ferrugineo-pube- 
rulis, circiter 7 mm altis. 
A tree 17 to m m bigb. Branches terete, slender, ultimately glabrous, 
sparingly lenticellate, dark-reddish-brown to nearly black, the branchlets 
rather densely ferruginous-pubescent. Leaves alternate, oblong-lanceo- 
late, subcoriaceous, 8 to 14 cm long, 2.5 to 4 cm wide, the base acute, the 
apex gradually narrowed to the rather slender, caudate, blunt acumen, 
the margins entire, the upper surface shining, glabrous, or when young 
very slightly pubescent, the lower surface paler, when young more or less 
ferruginous-cinereous-puberulent, especially along the midrib and nerves, 
apparently glabrous in age or nearly so; nerves about 10 on each side of 
the midrib, distinct beneath, obscurely anastomosing, the reticulations 
indistinct, nearly obsolete; petioles 5 to 10 mm long, usually pubescent. 
Female flowers spicately disposed, the spikes fascicled in the upper axils 
or arranged in terminal 5 to 7 cm long, panicles, ferruginous-pubescent. 
Glans oblong-conical-ovoid, 1.5 to 2 cm long, more or less puberulent, 
apiculate, 8 mm in diameter in the type, in other specimens 9 to 12 mm 
in diameter below. Cup about 7 mm high, including the thickened stipe, 
10 to 12 mm in diameter, inclosing only the base of the glans, more or less 
ferruginous- or cinereous-pubescent outside, nearly glabrous within, the 
laminae about 7, concentric, denticulate, the teeth very short, acute. 
Type specimen from Lamao River, Mount ilariveles, Province of Bataan, Luzon, 
For. Bur, 800 Borden, May, 1904, at an altitude of about 700 m. I am disposed 
to refer here also tiie following specimens: Elmer 0S!)7, November, 1904; Whitford 
276, May, 1904, from the same locality: Province of Ilocos Sur, La Paz, For. Bur.

The species as liere described is the Mariveles form, and some of the other 
specimens referred to it differ in some minor characters, in some specimens 
{Curran lOGU), the leaves bung quite glabrous. It is well characterized by its 
small fruits, which are consideriil.ly lunger than thick. The species figured by 
Vidal in his Sinopsis, Atlas, t, i)Z, f. A,, as doubtfully representing Quercus 
cekbica Miq., is probably referable here. It is certainly not I^Iiquera species.
