Trilliaceae

Trilliaceae was a family of flowering plants first named in 1846; however, most taxonomists now consider the genera formerly assigned to it to belong to the family Liliaceae.

The APG IV system, of 2016 (unchanged from the APG system, of 1998), does not recognize such a family either and assigns the plants involved to family Melanthiaceae, tribe Parideae.

Nevertheless, some taxonomists still recognize a separate family Trilliaceae.

A recent treatment (Farmer and Schilling 2002) stated that the family Trilliaceae, which exhibits an arcto-tertiary distribution, comprises six genera.

Three of these exhibit a wide distribution: Three are monotypic, endemic genera: Within Melanthiaceae, these are consolidated into three genera;
