Discussion

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.
