calycal

Calycal is a term that can refer to several different concepts depending on the context. In botany, a calycal is a ring of small, often petal-like structures that surround the base of a flower's calyx. These structures, also known as epicalyx or accessory calyx, are not true sepals but are accessory to the calyx. They are found in some plant families, such as the Malvaceae (mallow family), where they can contribute to the overall appearance and function of the flower, sometimes aiding in pollination or protection.

In a broader, less common usage, calycal might be employed as an adjective to describe something related to a calyx or calyces. This could pertain to features or characteristics associated with the outermost whorl of floral leaves. However, the botanical definition of epicalyx is the most established and frequently encountered meaning of the term calycal in scientific literature. The presence and form of a calycal can be a distinguishing feature for plant identification.
