An article reviewing all the current research into this interesting phenomenon in some cacti. Vivpary is “live birth”, normally more usually applied to animals. For example, a viviparous lizard is one which does not lay eggs like other lizard species, but gives birth to live young. To date there are 77 taxa that show this characteristic.
