Amphilophium is a genus of flowering plants in the family Bignoniaceae, native to South America. Amphilophium crucigerum (syn. Pithecoctenium crucigerum) has escaped from cultivation elsewhere, and has become an invasive weed in Australia.

Taxonomy

The genus Amphilophium was erected by Kunth in 1818, the type species being Amphilophium paniculatum, transferred from Bignonia. Many other genera have since been synonymized with Amphilophium.
