Distribution: Distributed from Mexico to Bolivia, it usually grows in disturbed vegetation ( Wood et al., 2020). In Brazil, it is naturalized in the Caatinga, Cerrado and Atlantic Forest domains. It occurs in the Northeast region, except in Alagoas and Piauí states, in the Center-West, in Goiás, and in the Southeast in Minas Gerais ( Simão-Bianchini et al., 2024). It is occasional in Paraiba, found in all IRs in areas of Caatinga, Atlantic Forest or ecotones.

Notes:This species is similar to I. alba , in its aculeate branches. However, they are easily distinguished by the rostrate sepals and hypocrateriform corolla, which is white in I. alba (vs. smooth sepals and infundibuliform corolla, which is bluish in I. parasitica ).
