fatuy A. tomeniosa^ and many called A* serpenta- 

 riay because they have consimilar leaves and roots, 

 while the flowers are different. The A. serpentaria

Aristolochia belongs with Asamm to the natural 

 order of Asarides. Linnaeus has put it into Gi'nan--

and limestone regions.

 aromatic smell, somewhat similar to Valerian and
