Male flowers and fruits unknown. Female inflorescence axillary, 
solitary, rather lax, paniculate, about 6 cm long, slightly pubes- 
cent; bracts oblong-lanceolate, acuminate, 3 mm long or less. 
Calyx about 1.5 mm long, irregularly splitting into 3 or 4, ovate- 
lanceolate, acuminate lobes. Ovary globose, densely covered 
with pale waxy glands, 1-celled, 1-ovuled ; stigma lateral, simple, 
papillose throughout, somewhat curved, tapering, 5 to 6 mm 
long. 
Mindanao, District of Zamboanga, Sax River Mountains back of San 
Ramon, Merrill 8076, November 28, 1911. In forests on ridges, altitude 
about 1,100 m.

A shrub or small tree reaching a height of about 4 m. Branches 
terete, slender, glabrous, smooth, reddish or reddish-brown, the 
branchlets slightly puberulent. Leaves alternate, membrana- 
ceous, oblong-ovate or ovate, 8 to 15 cm long, 5 to 8.5 cm wide,

narrow, about 0.5 cm deep, the apex prominently and rather 
slenderly acuminate, the margins slightly subrepand-denticulate 
or nearly entire, the upper surface glabrous, somewhat shining, 
with usually two glands on either side of the midrid at the 
base, the lower surface slightly paler than the upper, with few, 
scattered glands, the midrib and nerves often slightly ciliate;
