892 LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 50 
crooked, 3 to 7 cm. thick, terete; branches mostly at the top, the 
lax branchlets horizontally spreading, the ultimate ones only 
slightly ascending, the young portion usually somewhat compres- 
sed and short strigulose; wood soft, sappy white, with a large 
pith; bark smoothish, brown, easily peeling. Leaves opposite, 
with only a few pairs at the ends of the branchlets, sub- 
membranous, flat and with the sharply acuminate tips somewhat 
recurved, dark green and with cystoliths on the upper glabrous 
side, much paler green beneath, ovately oblong or the small 
ones lanceolate, the larger lamina 2 dm. long by 3.5 cm. 
wide across the middle or just below it, subcrenately dentate 
except the basal entire margin, the apex gradually tapering, 
base rounded, the smaller blades only 3 em. long; veins 3 
from the base, the lateral pair extending two thirds the 
length of the blade, the 3 to 5 minor lateral pairs from 
above the middle, cross bars and reticulations quite con- 
spicuous beneath, all brown and more or less strigulose beneath; 
petiole about 3.5 cm. long, strigulose or with cystoliths; 
stipule subpersistent, 1 cm. long, gradually tapering from the 
base to the slender point, brown membranous, the middle dorsal 
region covered with fine cystoliths. Pistillate inflorescence or 
infrutescence yellowish green, pendulous, axillary, 2 to 3 dm. 
long, sparingly branched from near the base; flowers forming 
dense glomerules, rather evenly scattered and alternatingly 
arranged; bracts rather few, less than 1 mm. long, broadly 
lanceolate to linear, puberulent along the margins and the 
vein on the dorsal side; ovary with the perianth obovoidly 
compressed, 1.5 mm. long, slenderly pointed toward the 
base which is usually surrounded by a circle of hairs or 
minute bracteoles; perianth developing into conspicuous 
wings, truncately rounded at the top and terminated into 
a short finely toothed neck, only sparsely ciliate especially 
so along the edges, persistent; stigmas whitish, brown when 
dry, 2 mm. long, usually curved, puberulent from the slighdy 
thiekened middle portion up to the tip; fruit 2 mm. long, 
much compressed, the side above the middle bulged and 
1.25 mm. wide; seed lenticular, darker brown, at least 0.5 mm. 
wide from the side view; staminate flowers not seen.
