Introduction to the Aristolochiales |
 | | The Aristolochiales are a group of paleoherbs, a basal group of flowering plants. |
 | | The majority of the Aristolochiales are tropical, though a number of them range as far north as Canada, Scandinavia, and northern Japan. |
 | | Fossil Aristolochiales have been found in North America beginning in the Cretaceous, and macrofossil leaves are known through the Miocene. |
