  Aristolochia pistolochia is a herbaceous plant in the family Aristolochiaceae endemic to Mediterranean areas across southwest Europe.
  
  ## Description
  
  Aristolochia paucinervis is a perennial geophyte carnivorous plant. Its rhizome is formed by numerous cylindrical tubers. Leaves are ovate-triangular, sharp to marginalized with cartilaginous margins, with a glaucous underside and very marked nerves. Flowers are yellow on the outside and dark reddish or green on the inside. It is similar to Aristolochia paucinervis, but can be easily distinguished by its thick, jagged leaf border.
  
  ## Distribution and habitat
  
  Aristolochia pistolochia is distributed throughout southwestern Europe, including the Iberian Peninsula (in Portugal and Spain), southern France, Corsica and Sardinia. It inhabits clearings of bushes, heaths or holm oaks groves, fallows and rocky areas in basal and montane floors.
