Epicalyx-additional whorl of calyx of a flower.which is modification of bract(found in cotton)of malvaceae member with monoadelphus

Family: Malvaceae
The presence of epicalyx and Monoadelphous condition of stamens is a characteristic feature of the family Malvaceae.

Epicalyx:
The epicalyx is a group of bracts that resemble a second calyx and is found just below the calyx in some plants. It is a characteristic feature of the family Malvaceae. The epicalyx may consist of several bracts or may be absent altogether. It functions to protect the developing flower bud and may also play a role in attracting pollinators.

Monoadelphous condition of stamens:
The term "monoadelphous" refers to the condition of stamens being united into a single group or column. In the family Malvaceae, the stamens are fused at their bases and form a column that surrounds the styles and pistil. This condition is known as monoadelphous condition of stamens and is a characteristic feature of this family. The fused stamens may have their filaments united into a tube or may be fused only at the base.

Other characteristics of the family Malvaceae:
- The family Malvaceae is a large family of flowering plants that includes around 244 genera and 4225 known species.
- The plants in this family are mostly herbs, shrubs, or small trees.
- They have alternate leaves that are usually palmately veined.
- The flowers are typically large and showy, with five petals that are often fused at the base.
- The fruit is usually a capsule or a schizocarp (a dry fruit that splits into segments when mature).
- Many species in the family Malvaceae have mucilaginous sap, which gives them a slimy or viscous texture when crushed.

Examples of plants in the family Malvaceae:
- Hibiscus: Hibiscus is a genus in the family Malvaceae that includes many species of flowering plants known for their large, colorful flowers.
- Alcea (Hollyhock): Hollyhocks are tall flowering plants in the genus Alcea that belong to the family Malvaceae. They are commonly grown in gardens for their showy flowers.
- Malva (Mallow): Malva is a genus in the family Malvaceae that includes several species of herbaceous flowering plants. Some species of Malva are used in herbal medicine and as culinary herbs.

In conclusion, the presence of epicalyx and the monoadelphous condition of stamens are characteristic features of the family Malvaceae. These features, along with other characteristics such as large showy flowers and mucilaginous sap, help in identifying plants belonging to this family.
