Distribution A family primarily restricted to the dry regions of the Southern Hemisphere, consisting of about 55 genera and 1200 species of which the majority are Australian and South African. Eight genera are represented in the New World of which two are indigenous to Panama.
Note A number of species are cultivated in numerous parts of Central America for their extremely showy inflorescences. At present I have no evidence of cultivated species in Panama.
