The Xyridaceae are a family of flowering plants. The botanical name has been recognized by many taxonomists and is known as the yellow-eyed grass family. The APG II system, of 2003 (unchanged from the APG system of 1998), also recognizes this family, and assigns it to the order Poales in the clade commelinids, in the monocots. This treatment in APG II represents a slight change from the APG system of 1998, which had recognized the family Abolbodaceae for some of the plants included here; that family was unplaced as to order, but was assigned to this same clade (although APG used the spelling "commelinoids").
