Webster's Revised Unabridged Dictionary
    • a Viviparous (Biol) 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.

Century Dictionary and Cyclopedia
    • viviparous Bringing forth alive; having young which maintain vascular vital connection with the body of the parent until they are born in a comparatively advanced stage of development; reproducing by birth, not by hatching from an egg which is laid and afterward incubated: correlated with oviparous and ovoviviparous. See these words, and egg. In strictness, all metazoic animals and some protozoans are oviparous, since they produce ova; but the distinction subsists in the duration of the period in which the product of conception remains in the body of the parent. If the egg is quickly extruded. the animal is oviparous; if it is separated from the mother, but hatches inside the body, ovoviviparous; if it comes to term in a womb, viviparous. Among vertebrates, all mammals excepting monotremes, no birds, many reptiles, and some fishes are viviparous. Invertebrates are mostly oviparous, in some cases ovoviviparous, in a few viviparous.
    • viviparous In botany, germinating or sprouting from a seed or bud which is still on the parent plant. The term is also sometimes equivalent to proliferous as applied to grasses, rushes, sedges, etc. See prolification, From an examination of the structure of viviparous grasses. Masters, Teratol., p. 169.
