Hi, occasional lurker in alt.home.lawn.garden (it's very quiet over there)
with something we need help identifying.

We have this really robustly growing vine with a very interesting flower
that neither one of us can identify- I posted a picture he
http://home.pacbell.net/o1o1o1o1/images/dsc_0002-33.jpg

Apologies about the clarity of the photo, I just don't have a macro lens,
and this is as good as I could get it.

It is about three inches across the tips of the petals. It's clinging to a
rose bush trellis like it owns it. Nature never ceases to amaze me- the
little 'arms' the hug its' companion are quite remarkable.

Noticed the flower opens and closes erratically- and only one bud at a time
(there are several buds on the vine). My wife tends the garden and notices
that if she touches the bud it closes and doesn't reopen for sometime.

Does anyone recognize it? Or perhaps give us clue as to where to find it?

We live in Southern California.

TIA,
