pomeis
/ˈpəʊmɪs/Heraldry
noun
(The name given to) a roundel or roundels when of a green colour. In early use usually treated as plural.
Origin
Mid 16th century; earliest use found in Gerard Legh (d. 1563), heraldic writer. Probably an alteration of pome, perhaps originally due to the reanalysis of an irregular plural form.
