I am new to this site.Please help me identify this vine.It is currently growing in South West Florida.The flowers are "fleshy" and only bloom for one day before falling off.

Thank You for any help.

dutchmans pipe or aristolochia

 

Thank you,Pierrot, for the quick identification.We have so many unsual plants down here,it is hard to tell the natives from the exotics.

 

Looks like Aristolochia elegans
They are unusual, aren't they? :-)

Barvinok,
It is indeed an Aristolochia Elegans.I no longer have to listen Pod People jokes from my friends.
Thankyou
