Ecdeiocoleaceae
Encyclopedia
Ecdeiocoleaceae is the botanical name
for a family
of flowering plants. Such a family has rarely been recognized by taxonomists.
The APG II system
, in 2003 (unchanged from the APG system
, 1998), does recognize such a family, and assigns it to the order Poales
in the clade commelinids
, in the monocots. Two species in separate genera Ecdeiocolea
and Georgeantha, both found in Southwest Australia
, have been described to date. A third and hitherto undescribed species is being studied.
