The provided source material does not describe a city named Tepal in Indonesia; rather, it defines "tepal" as a botanical term. A tepal is one of the outer parts of a flower used when these structures cannot be easily classified as either sepals or petals.
This classification occurs when the parts of the perianth are undifferentiated, such as in the Magnolia genus, or when the sepals and petals have a similar appearance despite being distinct whorls. The term was constructed by analogy with "petal" and "sepal" and was proposed by Augustin Pyramus de Candolle in 1827.
