Tepal
Tepal
Tepal (pronounced: /ˈtiːpəl/) is a term in botany used to describe a part of a flower. It is often used when it is not possible to distinguish between sepals and petals in a flower, or when they are similar in appearance and seem to form a single whorl.
Etymology
The term "tepal" was first coined by Augustin Pyramus de Candolle in 1827. It is derived from the Greek words "teino" (to stretch) and "petalon" (petal), referring to the petals and sepals stretching together to form a single unit.
Description
Tepals are the segments of the outer whorl in a flower that encloses the reproductive parts. They are found in flowers where the sepals and petals look alike, such as in lilies and tulips. In some plants, the tepals are brightly colored and petal-like, while in others, they are green and sepal-like.
Related Terms

- Perianth: The non-reproductive parts of the flower, consisting of the sepals and petals (or tepals, in some cases).
