Ivysaur evolves into Venusaur. In the main series games that use level-up evolution, Ivysaur pokemon evolves from Bulbasaur at level 16, and evolves to Venusaur at level 32. This is a family of three generations from a plant, starting with Bulbasaur, then Ivysaur and finally, Venusaur. Venusaur's flower bud on its back grows into a large flower upon evolution. This allows trainers to evolve Bulbasaur to Ivysaur and finally Venusaur in appropriate games, the normal way.
