1. STERCULIA Linnaeus 
Trees with simple, entire or lobed, or digitately compound leaves, the 
inflorescence axillary, panicled. Flowers polygamous. Calyx tubular or 
funnel-shaped, 4- or 5-parted, the lobes spreading or cohering by their tips. 
Petals none. Staminal-column bearing a head or ring of sessile anthers. 
Ovary sessile or stipitate, of 4 or 5, 2- to many-ovuled carpels; styles connate 
below; stigmas radiate. Fruit a small or large, inflated, few- to many- 
seeded, coriaceous or woody follicle. (Latin in reference to the offensive 
odor of the flowers of some species.) 
Species about 100 in the tropics of both hemispheres, about 15 in the 
Philippines.

1. S. foetida L. Calumpang (Tag., Pamp.); Bangar (Il.); Bobog (Vis.). 
A spreading tree reaching a height of 20 m or more. Leaves crowded 
at the ends of the branches, digitately compound, the leaflets 7 to 9, glabrous, 
coriaceous, entire, elliptic-lanceolate, sharply acuminate, 12 to 18 cm long. 
Panicles axillary, appearing with the new leaves, erect. Flowers rank- 
smelling, dull-yellowish or purplish, 2 to 2.5 cm in diameter, the caiyx-lobes 
oblong-lanceolate, acuminate, longer than the tube, villous within. Follicles 
large, woody, red, nearly glabrous, obovoid, about 10 cm long. Seeds 10 to 
15. (FI. Filip. pl. 134.) 
Occasional in our area, fl. March—Apr.; aligns the Philippines. 
Eastern Africa to India through Malaya to northern Australia. 
2. S. luzonica Warb. 
A glabrous spreading tree 6 to 10 m high. Leaves elliptic-ovate to 
elliptic, simple, entire, 8 to 17 cm long, acute or obtuse, hase cordate. 
Panicles in the upper axils, glabrous, peduncled, rather lax. Flowers 7 
to 8 mm long, glabrous outside, pubescent within, the calyx-lobes oblong, 
spreading. Follicles thickly coriaceous, red, inflated, pubescent, shortly 
stalked, falcate, 5 to 6 cm long, beaked. Seeds few. 
Rare in Singalon, fil. Dec.Mar.; widely distributed in the Philippines 
along the seashore. Gilolo. 
3. S. oblongata R. Br. 
A tree, glabrous or nearly so, 12 m high or less. Leaves simple, entire, 
oblong, 12 to 20 cm long, shortly acuminate, base rounded. Panicles in the 
upper axils, narrow, slender, many-flowered, equaling or longer than the 
leaves. Flowers 5 to 6 mm long, somewhat hairy, the calyx-lobes linear, 
ciliate, cohering by their tips. Follicles oblong, inflated, thickly coriaceous, 
red, obtuse, densely pubescent, about 5 cm long and 3.5 cm wide, sessile. 
Seeds 4 to 6, about 1.5 cm long. 
Uncommon in our area, fl. Sept.—Oct.; widely distributed in the Philip-
