Aristolochia L.

Aristolochia, as currently understood (see Ohi-Toma & al. 2006), is a genus of ca. 120 species in the warm-temperate and tropical regions of the Old World (mainly in eastern and southern Asia). All New World members of the genus Aristolochia are now accommodated in several segregate genera, including Isotrema (see there).

1. Flowers 2-8 together, 2-3 cm long. Leaves distinctly petiolate (petiole 15-50 mm long) === Aristolochia clematitis

1. Flowers solitary, 3-5 cm long. Leaves (sub-) sessile, amplexicaul === A. rotunda
