Kalanchoe × laetivirens

Kalanchoe laetivirens is a species of Kalanchoe (section Bryophyllum). It is probably a hybrid between K. daigremontiana and K. laxiflora (syn. Bryophyllum crenatum), and therefore a group of invalid names for such a hybrid, including Kalanchoe crenodaigremontiana, Kalanchoe crenato-daigremontiana, Bryophyllum crenodaigremontianum and Bryophyllum crenato-daigremontianum, are just synonyms of K. laetivirens.

It is often misidentified as one of its putative parents, K. daigremontiana, which has bands or spots on the back of leaves, while the leaves of K. laetivirens are completely green, as indicated by its epithet laetivirens which means "lushly green".
