Amphilophium crucigerum is a species of flowering plant in the family Bignoniaceae, native from Mexico through Central America into South America as far south as Argentina.[1] It was first described by Carl Linnaeus (as Bignonia crucigera) in 1753.[2] The synonym Pithecoctenium crucigerum has often been used.[1]

The species has become an invasive weed in Australia.[3] Chemical investigation of methanol extracted from this species yielded the iridoid glycoside theviridoside along with five phenylethanoid glycosides (verbascoside, isoverbascoside, forsythoside B, jionoside D and leucosceptoside B), these last all active against DPPH.[4]
