A 
An erect shrub about 2.5 m high, glabrous except the inflo- 
rescence, the branches terete, wrinkled, about 1 cm in diameter. 
Leaves membranaceous or somewhat chartaceous, suborbicular 
in outline, about 25 cm long, deeply 5-lobed, the base subtrimcate, 
7-nerved, the lobes oblong, 5.5 to 7 cm wide, extending one-half 
to two-thirds to the base, the sinuses rounded, the tips shortly 
and abruptly apiculate, the margins distantly denticulate, not at 
all lyrately lobed, both surfaces shining when dry, the upper sub- 
olivaceous, the lower slightly paler; petioles about 30 cm long, 
the lower half with prominent, scattered, oblique crests about 2 
mm wide, their margins pectinate, the laciniae slender, 1 to 1.5 
mm long, the lower crests surrounding the petioles, the upper 
ones reduced in length. Inflorescences terminal, umbellate, the 
peduncles about 1.5 cm long, all parts more or less furfuraceous, 
the primary branches about 15, slender, up to 5 cm in length; 
each branch bears a pair of ovate, about 3 mm long bracts about 
2 cm above the base subtending a short-peduncled sterile head 
and often an additional long-peduncled fertile one, the sterile 
heads dense, 4 to 7 mm in diameter, their peduncles 1 cm long 
or less, the peduncles of the fertile heads 2 to 2.5 cm long and 
bibracteate at about the middle. Fertile heads in fruit 10 to 12 
mm in diameter, the fruits crowded, sessile, ovoid, longitudinally 
3-sulcate, 3-angled, 3-celled, about 6 mm long.

The alliance of this species is apparently with Boerlagiodendron luzon- 
iense Merr., from which it is readily distinguished by its thinner leaves, 
the lobes denticulate but not at all lyrately lobed, the numerous scattered 
crests, 3-celled fruits, and other characters.

Frutex glaber, ramis teretibus, circiter 1 cm crassis; foliis 
usque ad 28 cm longis, chartaceis, 3-lobatis, basi subtruncatis 
ad late cordatis, lobis oblongis ad oblongo-obovatis, margine dis-

An erect, apparently simple shrub, glabrous except the inflo- 
rescence. Branches wrinkled, terete, about 1 cm in diameter. 
Leaves 22 to 28 cm long, up to 30 cm in width across the lateral 
lobes, chartaceous, brownish or olivaceous-brownish when dry,
