Petrea is a genus of evergreen flowering vines native to Mexico and Central America. They have rough-textured leaves, hence the common name "sandpaper vine". It looks somewhat similar to a tropical Wisteria.
Shown here is Petrea volubilis. Carolus Linnaeus named Petrea in honour of Robert James Petre, 8th Baron Petre of Ingatestone Hall in Essex. Petre was a patron of botany.
