This member of the Aristolochiaceae
family was given this name by Carl von Linnaeus in 1753. It is found in
Albania, Bulgaria, Corse, France, Greece, Italy, Sardegna, Sicilia,
Spain, Switzerland, Turkey-in-Europe and Yugoslavia, growing in a well drained but rich soil with
quite some water and little sun. The caudex can grow to three centimetres in diameter
and 25 centimetres long, the entire plant
from 20 to 60 centimetres in height. The flowers are yellowish-green
with a prominent, dark-brown or dark purple flap.
This species is the
only host plant of the caterpillars the southern festoon; a beautiful
uncommon butterfly; Zerynthia polyxena. The plant contains
aristolochic acid, which is poisonous.
The genera name originated from
Latin Aristatus; 'awnes' for the awn-like leaf tips, OR, more
likely: 'best birth'; as AristoTheophrastus
describes it use at childbirth. The species name means 'round' the
rounded shape of the leave.
