Eucalyptus cladocalyx is commonly cultivated in southern California.

Eucalyptus corynocalyx F. Mueller is an illegitimate name based on the same type as E. cladocalyx. Mueller may have thought corynocalyx (club-calyx) was a more appropriate name than cladocalyx (branch-calyx) and intended to change the name. The closed bud of this species is clublike.
