Flowers dicecious or rarely moneecious, apetalous. Disk 0. Male: 
Calyx small, usually 3-lobed, rarely 2-lobed, very rarely 4—5-lobed ; lobes 
slightly imbricate. Stamens 2-3, exserted; filaments free; anthers 
longitudinally dehiscent. Rudimentary ovary 0. Female: Calyx 3- 
(rarely 4—5-) lobed. Ovary 3-celled ; ovules in each cell solitary ; styles 
3, shortly connate below, free above, entire. Capsule 3-dymous, 
breaking up into three 2-valved cocci. Seeds globose, without a caruncle ; 
albumen fleshy; cotyledons broad, flat.—Trees or shrubs, everywhere 
glabrous. Leaves alternate or opposite, entire or crenulate, usually 
firm ; stipules usually minute. Flowers in 1-sexual (less often 2-sexual) 
stout or slender axillary spikes which accompany the leaves; males 
usually dense, females more lax with the flowers distinctly pedicelled ; 
pedicels usually solitary to their bracts, occasionally in threes; bracts 
usually densely imbricate and glandular. 
Species about 20, in the tropics of the Old World, rare in Africa, absent from 
America. 
The genus Excecaria, as here understood, is distinguished from Sapium by 
having only lateral inflorescences. The solitary Tropical African species has, however, 
been referred by Pax and K. Hoffmann, as a distinct section, to Spirostachys, 
Sond., from which it differs in having free filaments. Miiller has included both 
Sapium and Spirostachys under Excecaria; Kuntze has included both Excecarie 
and Spirostachys under Sapium. Bentham, while including Spirostachys under 
Excecaria, has kept the latter genus apart from Sapium because in Excecaria, «§ 
understood by him, the calyx is more deeply lobed than it is in Sapewm.
