verticillatis, ramulis 4-anguIatis ; floribus breviter pedicellatis, 
in ramulis ultimis subcapitato confertis. 
A tree about 10 m high, entirely glabrous. Branches dark- 
brown, distinctly 4-angled, the branchlets paler, 4-angled and 
narrowly 4-winged, the wings about 1 mm wide. Leaves op- 
posite, coriaceous, pale-greenish when dry, of the same color 
and shining on both surfaces, 18 to 22 cm long, 5.5 to 7 cm 
wide, somewhat narrowed upward to the acuminate apex, the 
base broadly rounded, cordate, subsessile, the petioles at most 
1.5 mm long; nerves impressed on the upper surface, very prom- 
inent on the lower, the transverse ones straight or nearly so, 
12 to 15 on each side of the midrib, anastomosing at from 5 to 
8 mm from the margin with the slightly arched, equally prom- 
inent, longitudinal nerves which extend from the base nearly 
or quite to the apex ; primary reticulations lax, faint, the others 
obsolete. Panicles terminal, about 7 cm long, paniculate, 
branched from the base, the branches opposite, the branchlets 
verticillate, the lower primary branches up to 6 cm in length, 
all distinctly 4-angled, dark-brown when dry. Flowers nu- 
merous, shortly pedicelled, densely crowded in globose, sub- 
capitate, partial inflorescences about 1 cm in diameter at the 
tips of the ultimate branchlets. 
Luzon, Tayabas Province, Atimonan, For. Bur. 2Jt932 Bawan, December 
12, 1915, on forested ridges, altitude about 200 meters, locally known as 
guis-guis. 
A characteristic species in the alliance with Memecylon terminalifloruvi 
Elm. and M. pteropus Merr., differing from the latter in its sessile, much 
shorter inflorescences and larger leaves, and from the former especially in 
its globose, subcapitate partial inflorescences, its differently shaped, thicker 
leaves, its prominently 4-winged branchlets, and its sessile inflorescences.
