XIV. 4 Merrill: Noteworthy Philippine Plants, XV 389 



A scandent shrub, the younger parts, petioles, and leaves on 

 the costa above and on the costa, nerves, and reticulations 

 beneath more or less ferruginous-pubescent. Branches terete, 

 slender, very dark-brown, somewhat rugose. Leaves obovate 

 to elliptic, subcoriaceous, 14 to 20 cm long, 8 to 12 cm wide, base 

 broadly rounded, distinctly cordate, sometimes slightly inequi- 

 lateral, apex rounded, truncate, or shortly and obscurely apl- 

 culate, the upper surface olivaceous, shining, glabrous except 

 the midrib, the lower surface brown, at times slightly glaucous; 

 lateral nerves about 13 on each side of the midrib, very prom- 

 inent on the lower surface, straight or slightly curved, anas- 

 tomosing near the margins, 'the primaiy reticulations subparallel, 

 prominent; petioles stout, about 4 mm long, more or less pu- 

 bescent, ultimately nearly glabrous. Infructescences axillary, 

 the peduncles 2.5 to 3 cm long, dark-brown, ultimately glabrous, 

 each bearing 20 to 25 subglobose to ovoid-globose fruits, the 

 infructescences rather dense, globose, about 3 cm in diameter; 

 fruits red when mature, acid, about 8 mm in diameter, spar- 

 ingly pubescent, apiculate, dark-brown when dry, their pedicels 

 about 8 mm long. 



Luzon, Laguna Province, Mount Maquiling, along Molauln 

 River, For. Bur. 26360 Mabesa, in forests, altitude 400 to 500 

 meters. 



The alliance of this species is with Oxymitra obtusifolia Elm. 

 and 0. longiflora Merr., from which it is distinguished by its 

 much broader leaves and nearly globose fruits.
