Dist: Cosmopolitan, and polymorphic; a number of varieties and segregate species have sometimes been recognized, but need additional study.

ID notes:Can only be mistaken for J. ranarius or depauperate J. tenuis: J. bufonus can be distinguished from J. tenuis by its small stature and inflorescence beginning just a few inches above the ground. Very similar to J. ranarius (see characters in key).
