viviparous

Meanings

1. 1
   adj

   producing live young that developed inside the parent's body rather than laying eggs

   Most mammals are viviparous, although the platypus and echidnas lay eggs.

2. 2
   adj

   botany: producing young plants or shoots that begin developing while still attached to the parent

   The viviparous mangrove seedling starts growing before it drops into the water.

From Latin viviparus, 'bringing forth live young,' formed from vivus, 'alive,' + parere, 'to bring forth or give birth.' The botanical sense applies the same idea to propagules that develop before separating from the parent plant.
