Kalanchoe × houghtonii

Kalanchoe × houghtonii is a hybrid between Kalanchoe daigremontiana and Kalanchoe delagoensis named after Arthur Duvernoix Houghton. It is often confused with Kalanchoe daigremontiana which has strongly cordate to auriculate or even peltate leaves, while the leaves of Kalanchoe × houghtonii are narrower and the leaf base is attenuate, cuneate to weakly cordate or auriculate.
