Krugiodendron ferreum in the flora area is found along the Atlantic coast from Brevard to Monroe counties. It is cultivated in gardens and parks as a specimen tree. Krugiodendron acuminatum was described from collections far-disjunct in Costa Rica and in Veracruz, Mexico. A. Pool (pers. comm.) considers these collections to fall within the range of variability of K. ferreum.
