Discussion

Apparently native only in Kenya, Tanzania, and perhaps Mozambique, Hibiscus schizopetalus is widely cultivated in the Tropics and occasionally escapes. The occurrence in many H. rosa-sinensis cultivars of semipendulous, long-pedicelled flowers with variously

crenate, undulate petals suggests the involvement of H. schizopetalus. Hybrids between H. schizopetalus and H. rosa-sinensis can be called H. ×archeri W. Watson. Typification of H. schizopetalus was discussed by M. Cheek (1989).
