Phytolaccaceae - the Pokeweed Family
Diversity: A family
of
18 genera and about 135 species, both woody and (mostly) herbaceous
plants
with maximum diversity in the New World. Treated by Cronquist as
'broadly defined' (sensu lato) with
some included genera often treated as distinct families.
Distribution:
Found
throughout the tropics and subtropics - pantropical
-
with some taxa, including the 4 genera each with a single species in
Texas,
extending into temperate parts of the World.
Floral structure:
Significant features:
Placed by Cronquist as the basal element of the Subclass, mainly due to
partial syncarpy.
