MERRILL. 
A species well characterized by its small coriaceous leaves and small fruits, 
the 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 alia; foliis oblongo-lanceolatis, S ad 14 cm longis, 
basi acutis, apice sensim caudato-acuminatis, acuminibns obtusis, supra 
glabris, subtus pallidioribus, junioribus plus minus einereo-ferrugineo- 
puberulis, nervis utrinque circiter 10, subtus distinctis, reticulis subob- 
soletis; glandibus ol)longo-conico-ovoideis, puberulis, 1.5 ad 2 cm longis, 
8 ad 12 mm diametro; cupulis plus minus cinereo- vel ferrugineo-pube- 
rulis, circiter 7 mm altis. 
A tree 17 to 25 m high. 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. 
Gians 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 Mariveles, Province of Bataan, Luzon, 
For. Bur. 806 Borden, May, 1904, at an altitude of about 700 m. I am disposed 
to refer here also the following specimens: Elmer 6897, November, 1904; Whitford 
276, May, 1904, from the same locality: Province of Ilocos Sur, La Paz , For. Bur.

1903: Province of Rizal, Bosoboso, Merrill 2702, June, 1903: Province of Pangas- 
inan, For. Bur. 8277 Curran it Merritt, December, 1907 : Province of Camarines, 
For. Bur. 1067/4 Curran, June, 1908. 
The species as here described is the Mariveles form, and some of the other 
specimens referred to it differ in some minor characters, in some specimens 
( Curran 1061/4), the leaves being quite glabrous. It is well characterized by its 
small fruits, which are considerably longer than thick. The species figured by 
Vidal in his Sinopsis, Atlas, t. 92, f. A., as doubtfully representing Quercus 
celebica Miq., is probably referable here. It is certainly not Miquel’s species.
