pair of ovate 1 cm long bracts at about the middle and each with a terminal 
head of perfect flowers 1.5 to 2 cm in diameter. Sterile flowers, in the 
middle sessile head, many, pedicellate, the pedicels 1 to 2 cm long, with 
numerous basal bracteoles. Perfect flowers in the lateral heads many, 
sessile, crowded in dense ovoid heads, subtended by numerous small brac- 
teoles. Calyx somewhat funnel-shaped, more or less angular, 3 mm long, 
2 mm thick, truncate. Petals 5 or 6, oblong, in bud 4 mm long. Sta- 
mens 5 or 6. Ovary 5- or 6-celled. Fruit crowded in dense ovoid or 
ellipsoid heads 3 to 4 cm long, 2.5 to 3 cm thick, the individual fruits 
narrowly obovoid, strongly 5- or 6-ridged, 5- or 6-celled, the ridges acute.

ary, 1905. Specimens collected by Hallier near Zamboanga, Mindanao, and on 
Basilan Island in January and February, 1904.. may prove to be the same species. 
A species recognizable by its very large 10- to 14-lobed leaves and 5- or 6-merous 
flowers.

Arbor vel arbuscula; foliis glabris, submembranaceis, 20 ad 30 cm 
longis, palmato 5-7-lobatis, lobis irregulariter grosse sinuatis, acuminatis, 
inflorescentiis subglabris vel glabris; floribus 4-meris. 
A shrub or tree, glabrous or nearly so. Leaves 20 to 30 cm long, 
glabrous, submembranous, truncate or cordate at the base, palmately 5- 
to 7-lobed, the lobes reaching to within 3 to 5 cm of the base, the sinuses 
broad, rounded, the lobes 6 to 8 cm wide, irregularly toothed and each 
with two or three large lateral lobules, these lobules ovate to oblong, 
toothed, acuminate, 2.5 to 4 cm long; petioles about 40 cm long, and 
with three or four crests at the base. Umbels compound, the peduncles 
10 to 12, 2 to 3 cm long, subtended at the base by numerous oblong, 
deciduous, coriaceous, strigose bracts 1 to 1.5 cm long, the peduncles 
nearly glabrous, bibracteolate at the apex and bearing a sessile central 
head of sterile flowers and two lateral branches 2 to 2.5 cm long, each 
branch bibracteolate at about the middle and bearing a dense globose 
head of perfect flowers 1 cm in diameter or less, the bracteoles in both 
kinds of heads minute or wanting. Perfect flowers sessile. Calyx 
oblong, about 2 mm long, 1 mm thick, more or less quadrangular, glabrous, 
truncate. Petals 4, in bud 3 mm long. Stamens 4. Ovary 4-celled. 
Sterile flowers pedicelled, pedicels about 5 mm long, glabrous, ovaries

Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens 91, January, 1906: 
For. Bur. 3921 Hutchinson, March. 1906. 
A species recognizable by its 5- to 7-lobed leaves, nearly glabrous inflorescence, 
absence of bracteoles in the flower-heads, and by its 4-merous flowers. Among the 
Philippine forms most closely allied to an undescribed species from Luzon.
