Proboscidea Schmidel
In its current circumscription Proboscidea is a genus of seven species (Gutierrez 2011), all native to the warmer parts of the Americas. Its center of diversity lies in the southwestern U.S.A. and Mexico. A few species are cultivated as ornamentals (Knees 2000, Jäger & al. 2008) or for their edible fruits (young fruits are pickled). One of these, P. louisianica (Mill.) Thell., has been recorded as an alien in Belgium.
