coriaceous, shining; nerves 11 on each side of the midrib, distant, 
obscurely anastomosing, the reticulations obsolete or nearly so; 
petioles about 1.5 cm long; stipules somewhat sheathing, reddish- 
brown, about 1 cm long. Inflorescence terminal, peduncled, in 
flower about 5 cm long, very minutely puberulent, the flowers 
subumbellately arranged on the ultimate branchlets. Pedicel 
and calyx continuous, narrowly funnel-shaped, about 3 mm long, 
minutely 5-toothed. Corolla, in nearly mature bud, externally 
very slightly puberulent, 2.2 mm long, the tube 1 mm long, the 
lobes oblong-ovate, acute. Anthers 1.3 mm long. Fruit ovoid, 
fleshy and red when fresh, w^hen dry longitudinally 6-sulcate, 8 
to 10 mm long. Pyrenes plano-convex, longitudinally and prom- 
inently 3-sulcate on the back, about 8 mm long, 5 mm wide, 
elliptic-oblong. Seeds 6-ridged, sulcate on the back.

800 to 900 m. 
A species well characterized by its narrow leaves which are reddish- 
brown when dry, with distant nerves and obsolete or nearly obsolete reti- 
culations. It does not appear to be very closely allied to other Philip- 
pine forms.
