of flowering plants. Such a family has been recognized by most taxonomists.
The APG II system
, of 2003 also recognizes this family, and assigns it to the order Poales
in the clade commelinids
, in the monocots. This represents a slight change from the APG system
, 1998, which left the family unplaced as to order, but placed it in the same clade (although it used the spelling "commelinoids"). The family consists of probably less than a hundred species, found in tropical South America and tropical west Africa
.
The Cronquist system
, of 1981, also recognized this family and placed it in the order Commelinales
in the subclass Commelinidae
