Petalism

Webster's Dictionary 1913

Pet″al‐ism (?), n. [Gr. �, fr. � a leaf: cf. F. pétalisme.] (Gr. Antiq.) A form of sentence among the ancient Syracusans by which they banished for five years a citizen suspected of having dangerous influence or ambition. It was similar to the ostracism in Athens; but olive leaves were used instead of shells for ballots.
