NATURAL HISTORY OF PLANTS. 
known. They are trees, sometimes very high, natives of tropical 
America. The leaves are opposite, compound-digitate, with three’ 
or five thick folioles, often coriaceous, generally dentate or crenate. 
The petiole is sometimes furnished at the base with two caducous 
stipules. The flowers, generally large, purple or greenish, are 
arranged in terminal racemes. 
Beside Caryocar are placed Anthodiscus, consisting of trees or 
shrubs of the same region, which are only distinguished from them 
by their alternate trifoliate leaves; by their corollas, which are 
detached in a single piece at the base, like those of Marcegravia; by 
their stamens plainly grouped in five alternipetalous’ phalanges, 
by the numerous cells of their ovary,’ their almost orthotropal’ 
ovules, their coriaceous pericarp, and their embryo with rolled or 
spiral radicle. Three species’ of Anthodiscus are known. 
The family Zernstremiacee was distinguished in 1813 by 
B. Mirsen.’ Before him A. L. pr Jussinu® made the known plants 
of this group a special section of the Order Citrus (Fr., Orangers), 
characterized by its dry polyspermous fruits. It comprised, with 
Ternstremia (and Tonabea, wrongly preserved as distinct), Thea 
and Camellia, of which MrrBez also made a separate family under 
the name of Zheace@. Dn Canporrx adopted this method of 
arrangement, preserved as distinct the Order of Zernstremiacee,” and 
that of Theacee, which he named Camellice." In 1828, CAMBESSÈDES,

3 They are all united below in a short 
annular enclosure; then a bundle is detached 
opposite each of the teeth of the calyx, the 
middle filaments of which are much longer and 
inflexed in the bud; they then diminish in 
size until they meet the edges of the neigh- 
bouring bundles, and they are straight with 
erect anthers

unequal disc. The cells vary from eight to 
twenty. 
5 In A. peruanus the micropyle is superior, 
and the hilum is close to the base a little nearer 
the internal than the external edge. In other 
terms, the anatropal movement is scarcely in- 
dicated, and the ovule becomes ascendent,
