Calloideae is a monotypic subfamily of flowering plants in the family Araceae. The single genus in the subfamily is Calla , although in the past under Engler's description of Araceae it included four genera, namely Lysichiton , Symplocarpus , Orontium , and Calla . The subfamily was subsequently made monotypic and given a single tribe, Calleae. Species in Calloideae are often found in marshy habitats in the northern hemisphere. Trichosclereids are not found in the flowers.
