Aristolochia Baetica: A Possible Current or Vestigial Carnivorous Plant?

Abstract

Aristolochia baetica is a Mediterranean plant characterized by its purple flowers with the shape of small bells. The objective of this study is to determine whether this plant presents the behavior and characteristics of carnivorous plants. In the results obtained, it should be noted that its flowers have the ability to capture and retain insects, presenting mechanisms for their retention (hairs). Likewise, other mechanisms have been detected that could serve or have served for the absorption of nutrients, such as pores in the utricle or absorbent hairs. Therefore, it is probable that Aristolochia baetica is currently, or may be a vestige of a species of carnivorous plant.
