Bur. Sci. 23490 Ramos, August 3, 1915, with staminate flowers 
and the local Bikol name buyong halas: Laguna Province, Mount 
Maquiling, For. Bur. 26751 Mabesa, March, 1917, Elmer 18059, 
June, 1917. In damp forests at low and medium altitudes, as- 
cending to 450 meters on Mount Maquiling. 
A remarkable species not at all resembling any previously 
described form, easily recognizable by its broadly ovate, deeply 
cordate, equilateral leaves which are softly pubescent beneath; 
by its rather stout, cylindric, elongated spikes and their pubes- 
cent bracts; and by its large, long-pedicelled fruits.

Arbor magna, plus minusve pubescens; foliis tenuiter char- 
taceis, scaberulis, ovatis, integris, 5 ad 8 cm longis, acuminatis, 
basi inaequilateralibus, 3-nerviis, oblique truncatis ad rotundatis 
vel acutis; inflorescentiis pubescens, usque ad 5 cm longis, in-

A tree, about 25 m high, more or less pubescent. Leaves 
thinly chartaceous, rather scabrous, both surfaces with scat- 
tered, very short hairs, ovate, entire, 5 to 8 cm long, 3 to 5 cm 
wide, the base inequilateral, 3-nerved, somewhat oblique-truncate 
to rounded or even shallowly cordate, the younger leaves some- 
times acute, apex acuminate; nerves slender, including the basal 
pair usually 3 on each side of the midrib; petioles pubescent, 
about 5 mm long. Inflorescences axillary and from the axils of 
fallen leaves, the latter usually wholly staminate, the former with 
both male and perfect flowers, cinereous-pubescent, up to 5 cm 
long. Male flowers sessile, somewhat glomerate on.the branch- 
lets, 5-merous, about 4 mm in diameter, the sepals distinctly 
pubescent, oblong-obovate, 2 mm long. Stamens equaling the- 
sepals. Perfect flowers fewer than the male, sessile or short- 
pedicelled, the sepals 5, elliptic to oblong-elliptic, 2 to 2.56 mm 
long. Ovary oblong-ovoid, pubescent, the style arms forked. 
Stamens 5, filaments 2 mm long.

the local Tagakaolo name sikim. 
This species does not appear to be very closely allied to any 
previously described form. It is easily distinguished among 
the Oriental species with entire leaves by its indumentum and
