Tilioideae is a flowering plant subfamily in the family Malvaceae, though it was formerly considered a large group, placed at family rank and called Tiliaceae.
Within the framework of the Angiosperm Phylogeny Groups III[1] & IV systems,[2] an extended family Malvaceae is recognized by uniting the core Malvales of the Cronquist system - Bombacaceae, Malvaceae sensu stricto, Sterculiaceae and Tiliaceae. Within the APG classification, Malvaceae contains a clade of 3 living genera placed as the subfamily Tilioideae.
The subfamily includes Tilia, Craigia, and Mortoniodendron.[3] The majority of other genera historically included in the family rank "Tiliaceae" have been moved into two other subfamilies of Malvaceae, the Brownlowioideae and Grewioideae.
