Se"pal (?), n. [NL. sepalum, formed in imitation of NL. petalum, petal, to denote one of the divisions of the calyx: cf. F. s'epale.] Bot.

A leaf or division of the calyx.

⇒ When the calyx consists of but one part, it is said to be monosepalous; when of two parts, it is said to be disepalous; when of a variable and indefinite number of parts, it is said to be polysepalous; when of several parts united, it is properly called gamosepalous.
