Encyclopedia
Achatocarpaceae is a family
of woody
flowering plants. The family consists of two genera and ten species, and has been recognized by most taxonomists. It is found from the southwestern United States
south to tropical
and subtropical
South America

The APG II system
(2003; unchanged from the APG system
of 1998) assigns it to the order Caryophyllales
in the clade core eudicots. It forms a clade
together with Amaranthaceae
and Caryophyllaceae
, two very large families.
Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Clade
A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...
