ceous, shining deep green above and glabrous, horizontal and 

 flat except the abrupt acuminate recurved apex, base rounded, 

 the entire margin subinvolute in the dry state, drying black- 

 ish brown, glabrate beneath except the nerves, the normal 

 blades 7 cm. long by 4.5 cm. wide at the middle, the basal 

 ones of the twigs usually much reduced, ovately elliptic 

 but with sharp apical points; midrib fulvus pubescent be- 

 neath only; lateral nerves 6 to 8 pairs, ascending, sparsely 

 hairy, tips archingly united, cross burs few and very faint; 

 petiole less than 1 cm. in length, similarly hairy especially 

 in the young state, somewhat compressed; interaxillary stipule 

 at least as long as the petioles, membranous and brown, 

 caducous, boot-like, apex rounder!, Infrutescence suberect, 

 terminal, paniculately branched from above the middle, pro- 

 fuse, 1 to 3 dm. across; peduncles usually 3 from the same 

 place, somewhat compressed and fluted along its sides, at the 

 base usually subtended by stipular bracts; branches opposite, 

 divaricate, likewise rebranched from above the middle, at 

 the base subtended by very short and apiculate bracts and 

 apparently articulated; ultimate branchlets strict, bearing 

 few to several fruits toward the distal end; pedicels 2 to 

 4 ram. long, they as well as all the infrutescent stalks deep 

 brown; drupes dark green, obovoid in the fresh state, gray-

Type specimen number 13667, A. D. E. Elmer, Cabad- 

 baran (Mt. Urdaneta), Province of Agusan, Mindanao, Sept-

Climbing up to twenty feet above the moist stony ground 

 of a wind swept forested ridge of Cawilanan peak at 4000 

 feet altitude. "Simbanag" in Manobo. 



From P. diffusa Merr. it differs in having larger more 

 numerously nerved leaves. From P. ovalis Elm. in having 

 longer petioles, larger blades which are more sharply pointed 

 and much less pubescent beneath; its fruits are also thicker.
