December 6, 1913] Seven Oaks from Mount Urdaneta 1985 



ulate on the upper surface only; petiole 1 to 1.5 cm long, 

 subterete, also glabrous. Infrutescence mostly terminal from the 

 leaf bearing twigs or upon special branchlets; spikes generally 

 clustered, stout yet comparatively slender and flexible, terete, yel- 

 lowish gray when dry though glabrous, 1 to 2 dm in length, 

 frequently recurved or even pendant because of the heavy fruits; 

 glans 2.25 cm across and about as long, short and bluntly ovoid, 

 the upper one third exserted and short or appressed fuzzy brown 

 hairy, curing yellowish brown, truncately rounded at the apex 

 which bears the circularly sunken bluntly apiculate point; cup 

 Bub turbinate towards the short yet distinct stalk, 3.5 cm thick 

 across the middle, the basal portion fairly smooth or only obscurely 

 rugose toward the apical portion, rather densely ringed but without 

 apiculations or scales, cup with nut or glan 4 cm. long. 



Type specimen number 13965, A. D. E. Elmer ^ Cabadbaran 

 (Mt. Urdaneta), Province of Agusan, Mindanao, October, 1912. 



This fine oak was discovered in stony soil near a rocky 

 forested ridge along the Catangan creek at 3000 feet altitude. 

 The large heavy nuts are persistent, and often I have seen 

 the Manobos gather bunches of the branchlets with the fruit 

 and hang them up in their houses as ornaments. I myself 

 have in my study a bunch over a year old and from which 

 none of the acorns have as yet fallen. This also the Manobos 

 call "Li paeon." Dedicated to Dr. E. B. Copeland. 



Foliage similar to Quercus merrittii Merr. as well as to a 



few other allied Philippine species, but fruits dissimilar. Most 



closely related to Quercus apoensis Elm. but acorns longer and 

 cup twice as deep. 



Quercus bicolorata Elm. n. sp. 



Large tree; trunk over 1 m in diameter, 25 m high, 

 terete, somewhat crooked, branched from above the middle; 

 wood hard, tough and heavy, the white outer portion grad- 

 ually changing to the central more or less brownish color, 

 streaked with darker brown vessels; bark 2 cm thick, gray 

 and brown mottled, smooth or roughened with excrescences, 

 the inner one half testaceus, the balance latericius, easily 

 separating from the wood; main branches few, ascending, large, 

 crookedly rebranched; twigs numerous, glaucous green, ascending-
