This is Aristolochia gilbertii. This is a twining evergreen vine. As usual it has a very peculiar blossom. The bloom is a beak with a green background and speckled purplish brown foreground. All Aristolochia species, except for the Aristolochia gigantea, are larval host plants for the Pipevine Swallowtail, Polydamas Swallowtail, and Mylotes Cattleheart butterflies.
