Abrus

Pea Pea, n.; pl. {Peas}or {Pease}. [OE. pese, fr. AS. pisa, or OF. peis, F. pois; both fr. L. pisum; cf. Gr. ?, ?. The final s was misunderstood in English as a plural ending. Cf. {Pease}.] 1. (Bot.) A plant, and its fruit, of the genus {Pisum}, of many varieties, much cultivated for food. It has a papilionaceous flower, and the pericarp is a legume, popularly called a pod. [1913 Webster]

Note: When a definite number, more than one, is spoken of, the plural form peas is used; as, the pod contained nine peas; but, in a collective sense, the form pease is preferred; as, a bushel of pease; they had pease at dinner. This distinction is not always preserved, the form peas being used in both senses. [1913 Webster]

2. A name given, especially in the Southern States, to the seed of several leguminous plants (species of {Dolichos}, {Cicer}, {Abrus}, etc.) esp. those having a scar (hilum) of a different color from the rest of the seed. [1913 Webster]

Note: The name pea is given to many leguminous plants more or less closely related to the common pea. See the Phrases, below. [1913 Webster]
