324 MERRILL. 



A species well eliaracterized hy its small eoriaeeous leaves anil small fruits, 

 the involucres being rather densely einereoiis-i)ubesci^nt. In leaf characters some- 

 what similar to Qucrcus mcrrUUi Von Seem., hut the fruits are entirely diflerent.

A tree IT to 25 m higb. Branches terete, slender, ultimate^ glabrous, 

 sparingly lenticellate, dark-]-eddish-l)rown to nearly black, the l)rancblets 

 rather densely ferruginous-pubescent. Leaves alternate, ol)long-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, l)lunt acumen, 

 the margins entire, the upper surface sbining. gla1)rous, or when young 

 very slightly pubescent, tlie 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 aliout 10 on each side of 

 the midrib, distinct beneath, obscurely anastomosing, the reticulations 

 indistinct, nearly obsolete; petioles 5 to 10 mm long, usually ])ul)escent. 

 Female flowers spicately disposed, the spikes fascicled in tbc u])per axils 

 or arranged in terminal 5 to T 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 tbe type, in other specimens 9 to 12 mm 

 in diameter below. Cup about T mm high, including the thickened stipe, 

 10 to 12 mm in diameter, inclosing only the ba^se of the glans, more or less 

 ferruginous- or cinereous-pubescent outside, nearly glabrous witliin, tbc 

 laminte about T, concentric, denticulate, the teeth very short, acute. 



Type specimen from Lamao River, Mount Mariveles, Province of Bataan, Luzon, 

 Fur. fiur. 806 Borden, May, 1904, at an altitude of about 700 ni. I am disposed 

 to refer here also the following specimens: Elmer (iSDl, November, 1904; Whitford

The sjK'cies as here described is the Mariveles form, and some of the other 

 specimens referred to it ditVer in some minor cliaracters. in some specimens 

 {('iirniii lOli'i'i). the leaves being (piile ghilnons. It is well characterized by its 

 small fruits, wliich are consideiably longer tiian thick. Tlie s|(ecies (igiired by
