See text Corsiaceae is a family of monocotyledonous flowering plants.

The APG II system (2003) treats the family in the order Liliales, in the clade monocots.

This is a slight change from the APG system, of 1998, which left the family unplaced as to order, but did assign it also to the monocots.

The family is usually taken to include three genera, Corsia, Corsiopsis, and Arachnitis with a total of 27 known species.

The APG companion site cites a reference which suggests the family should consist of Corsia only, with Arachnitis better placed nearer to family Burmanniaceae.
