Trees with simple, entire or lobed, or digitately compound leaves, the 

 inflorescence axillary, panicled. Flowers polygamous. Calsrx tubular or 

 funnel-shaped, 4- or 6-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. 8. foetida L. Calumpang (Tag., Pamp.) ; Bangar (II.) ; Bpbog (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 calyx-lobes 

 oblong-lanceolate, acuminate, longer thah the tube,-villoUs within. Follicles 

 large, woody, red, nearly glabrous, obovoid, about 10 cm long. Seeds 10 to 

 16. (PL Filip. pi. iSi.) 



Occasional in our area, fl. March-Apr.; throughout the Philippines. 

 Eastern Africa to India through Malaya to northern Australia. 



2. 8. 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, base 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, fl. Dec-Mar. ; widely distributed in the Philippines 

 along the seashore. Gilolo. 



3. 8. oblongata R. Br. 



A tree, glabrous or nearly so, 12 m high or less. Leaves simple, entire, 

 oblong, .12 to 20 cm long, shortly acuminata, 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- 

 pines. Endemic.
