xiii. c, i Merrill: Philippine Plants, XIII 45 



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 subtruncate, 

 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.

 lobes, chartaceous, brownish or olivaceous-brownish when dry,
