three monospermous cells, and the alternate or opposite leaves 
are compound 3—5-foliolate. 
Toddalia, belonging to the warm regions of the Old World, has 
sometimes been considered as the type of a special tribe of this 
family, because its carpels are united into one single plurilocular 
ovary ; but after what we have seen, this character does not allow us 
to place them in any other series but that of Zanthorylon, whose 
general organization they have with unisexual 2—5-merous flowers, 
imbricated or valvate petals, an isostemonous androceum, uniovulate 
cells, coriaceous or fleshy fruit, an embryo surrounded by a 
fleshy albumen and alternate trifoliolate leaves, covered with 
glandular punctures. 
VI. AMYRIS SERIES. 
The flowers of Amyris' (figs. 447-451) are hermaphrodite or 
polygamous, with convex receptacle. The calyx is gamosepalous, 
with four teeth, imbricated when young. The corolla is formed of 
four alternate imbricated petals expanded at anthesis. The stamens 
are eight in number, superposed, four to the divisions of the calyx, 
and four shorter to the petals. Hach of them is formed of a free 
hypogynous exserted filament, and a two-celled introrse anther 
dehiscing by two longitudinal clefts. 
rudimentary in the male flower, is accompanied at its base by a disk 
more or less thick in the female or hermaphrodite flowers, when it is 
composed of a single one-celled carpel,? surmounted by a style short 
or almost wanting, more or less dilated, and covered above with 
stigmatic papilla. Upon the wall of the ovary cell a placenta is 
seen supporting two collateral descending ovules, with superior and 
exterior micropyle* The fruit is a globose or elongated drupe," 
accompanied at its base by the persistent calyx. The thin charta- 
ceous stone generally contains one seed, the coats covering a fleshy 
albumen with plano-convex cotyledons and short superior radicle.
