Angiosperm \An"gi*o*sperm\ (-[a^]n"j[i^]*[-o]*sp[~e]rm), n. [Angio- + Gr. ?, ?, seed.] (Bot.) A plant which has its seeds inclosed in a pericarp. Contrasted with gymnosperm.
Note: The term is restricted to exogenous plants, and applied to one of the two grand divisions of these species, the other division including gymnosperms, or those which have naked seeds. The oak, apple, beech, etc., are angiosperms, while the pines, spruce, hemlock, and the allied varieties, are gymnosperms.
Douglas Harper's Etymology Dictionary
"plant with seeds contained in a protective vessel" (as distinguished from a gymnosperm), 1853, from Modern Latin Angiospermae, coined 1690 by German botanist Paul Hermann (1646-1695), from Greek angeion "vessel" (see angio-) + spermos, adjective from sperma "seed" (see sperm). So called because the seeds in this class of plants are enclosed.
