Corsiaceae

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.

Arachnitis uniflora, the sole species in the genus Arachnitis, is a non-photosynthetic plant species in the family Corsiaceae. This species is mycoheterotrophic, and it obtains carbon from mycorrhizal fungi of the family Glomeraceae which are associated to its roots.
