A Butterfly’s Death Sentence

A Butterfly’s Death Sentence

The  Brazilian Dutchman’s Pipe (Aristolochia gigantea) is easily one of the  most impressive flowers I’ve ever seen. It is really as huge as it looks  in the picture, and just completely gorgeous. Plus, it has heart shaped  leaves. 😍
 

Beyond its beauty there are some signs that this  plant could be a source of some interesting phytochemicals. First, the  name of the genus is “Aristolocia” which comes from a combination of two  Greek words: ‘aristos’, meaning ‘best’, and ‘locheia’, meaning  ‘childbirth’.  This is due to both the look and old traditional uses of  the plant, as the flower resembles a human fetus (I think more when they  are emerging), and a European species that was used for pain or  infections of childbirth.  
 

In Brazil this plant is used in  traditional medicine for a number of uses, including having to do with  women’s health and childbirth, joint pain, snakebite, intestinal pain,  eczema and weight loss.  Also, related species are also commonly  reported to have traditional medicine uses.
 

This plant is  reportedly a “death sentence for pipevine swallowtail butterflies” (and  extremely toxic to humans). Apparently, the butterfly confuses it with  its native host Aristolochia, lays its eggs on the plant, and the larvae  end up dying because they cannot survive on its toxic foliage.
 

Beyond  some studies on the nephrotoxicity and carcinogenicity of the  Aristolochic acids it contains, however, there have been few studies yet  to confirm traditional uses or interesting chemistry of this plant.  Aristolochic acid is present in many of the Aristolochia species, which  is a known antitumor agent, but yet has proven too toxic for clinical  use.
 

One amazing feature about Brazilian Dutchman’s Pipe is its  strategy to ensure pollination. It is known as one of the ‘trap flowers’  of the world. The Brazilian Dutchman’s Pipe flowers lure  insects—primarily flies—through exuding a strong scent. As the flies  (who are dusted from other flowers) enter the calyx of the flower, they  get trapped by hairs that are pointed downward along the tube. Once the  fly is dusted with new pollen the hairs relax and let the fly escape and  visit other flowers. Some of these pollination strategies are so  complex it makes me wonder how they ever evolved.
