Viviparous


Definition:

  • (a.) Producing young in a living state, as most mammals, or as those plants the offspring of which are produced alive, either by bulbs instead of seeds, or by the seeds themselves germinating on the plant, instead of falling, as they usually do; -- opposed to oviparous.
