What does sepalous mean?
Sepalous is a botanical adjective describing something that has sepals, consists of sepals, or resembles them. Sepals are the usually green, leaflike parts of a flower that form the calyx around the base of the reproductive organs and often protect the developing bud. In a sepalous structure, sepals may have been modified into another form or may resemble these protective floral parts. The word is uncommon outside specialist botanical and horticultural writing, where it provides a concise way to describe a flower’s structure. Ordinary speakers will often understand the plainer expression "sepal-like" more readily. Sepalous is related to sepal, which comes through Modern Latin from a Greek word for a leaf or similar plant part. Although the adjective is not regularly encountered in modern prose, it follows a familiar English pattern of extending a noun with the suffix -ous to form an adjective.

Where does sepalous come from?
Sepalous was formed in English from sepal plus the adjectival suffix -ous. The noun sepal entered English in the early nineteenth century from Modern Latin sepalum, which derives from Greek sēpalon, a word for a leaf or plant part. The formation of sepalous belongs to the established English pattern of creating descriptive adjectives from nouns with -ous.
