Calycifloræ

Calycifloræ, a term introduced by De Candolle to include those natural orders of dicotyledons in which the sepals and petals are separate, as in Thalamifloræ, but in which the stamens, instead of being hypogynous, are perigynous or epigynous. As the most important calycifloral orders may be mentioned Roraceæ, Leguminosæ, Crassulaceæ, Saxifragaceæ, Umbellifere, Myrtaceæ, Onagraceæ, Cucurbitaceæ, Passifloraceæ, Celastraceæ, Rhamnaceæ, and Terebinthaceæ. The name expresses the view that the stamens stand upon a united calyx; the study of development has, however, long ago shown that they really arise as usual from the axis. See FLOWER.
