Botanists no longer use the term Calyciflorae to describe a group of plants. Flowers with sepals connected at least at the base (gamosepalous), a “torus” (disc) at the base of the calyx from which the petals and stamens appear to emerge, and an ovary that is either free or attached to the calyx were classified as Calyciflorae. Flowers with sepals that are at least partially connected at the base (gamosepalous), a “torus” (disc) at the base of the calyx from which the petals and stamens appear to emerge, and an ovary that is either free or attached to the calyx.
Calyciferae
Plants with cup-shaped thalamus and inferior or half-inferior ovary are included in this category. There are five orders and 27 families in the Calyciflorae family.
Calyciflorae is a polypetalous Dicotyledon subclass called after the insertion of the petals and stamens around the border of the receptacle tube, which was incorrectly referred to as the “calyx-tube.” This insertion can be perigynous or epigynous, depending on whether the tube is free of the ovary or attached to it. Leguminosae, Rosaceae, Saxifragaceae, Crassulaceae, and Umbelliferae are some of the most prominent families in the subclass. The order Rosales of the series Calyciflorae includes Fabaceae, which contains flowers with joined sepals and stamens and petals that appear to emerge from the base of the calyx.
Calyx
The calyx is a leaf-like structure at the base of a flower that protects the flower during development in many types of flowers. Sepals are the leaf-like components that make up the flower. These sepals are frequently as numerous as the petals. While most calyces are green, there are some instances where the calyx is the same colour as the flower’s petals or a completely different hue.
The calyx is an important part of the flowering plant. The flower is tightly closed into a bud as it develops. The sepals are the flower’s outer covering as it develops, and they are the only visible part of the bloom while it is still in bud form.
Formation of the Calyx
The calyx is the first portion of a flower to form, and it is linked to the plant’s stem immediately. Petals, like the rest of the flower, develop inside the calyx. When the flower opens, the calyx sepals are frequently placed in an alternate pattern with the petals. The tightly closed calyx can be thought of as a nursery for the developing flower. Until the flower’s development is complete and it is ready to bloom, it is tightly enclosed in the calyx.
Polypetalae
The plants were grouped together based on morphological similarities. Plants in the Polypetalae family have petals that are separated from the base or are just loosely linked. Bitegmic ovules are found in members of the Polpetalae family (i.e., ovules having two integuments). Polypetalae was a taxonomic classification system for identifying plants, however it is now thought to be a contrived classification system that does not reflect evolutionary history.

George Bentham and Sir Joseph Hooker devised a classification system based on seeded plant traits. This classification system was presented in three volumes in ‘Genera Plantarum.’ They divided dicotyledonae into three subcategories:
- Polypetalae: Polypetalae are plants with free petals. Thalamiflorae, Disciflorae, and Calyciflorae are the three subseries.
- Gamopetalae: Gamopetalae are plants with united petals. It’s separated into three series: Infobae, Heteromerae, and Bicarpellate.
- Monochlamydeae: these are plants that have a single whorl of perianth in their flowers. They have unfinished blossoms. Curvembryeae, Multivulatae aquatics, Multivulatae terrestris, Micro Embry Uae, Daphnoides, Chlamydospores, Unisexuales, and Ordines anomalies are among the eight series.
