The '''Xyridaceae''' are  a [[family (biology)|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").
 
 
 
The family contains almost 400 species in five genera,<ref name="Christenhusz-Byng2016">{{cite journal |author1=Christenhusz, M. J. M. |author2=Byng, J.

The [[Cronquist system]] of 1981 also recognized such a family and placed it in the order [[Commelinales]] in the subclass [[Commelinidae]] in class [[Liliopsida]] in division [[Magnoliophyta]].
 
 
 
The [[Wettstein system]], last updated in 1935, placed the family in order [[Enantioblastae]].
 
 
 
''Xyris torta'', twisted yellow-eyed grass, is on [[Minnesota]]'s [[endangered species]] list.
