The flowaers are on the ends of the new growth. As it puts out new growth the ends branch out several times and a flower form on the tips of each new branch. One of these is fully grown and about to open and the other one is fully open.
Baa, That looks like it. MsJen, It looks like the first picture. The Brazillian Firecracker vine. (Rubiaceae Manettia Cordifolia. Whatever it is, it will still be my hummingbird vine. I love it and so do they.
Thanks to all of you for your help. That was very generous of you to put in all of that time to look for the real name.
So we have a positive ID? Great! I'll move the photos to the M. cordifolia entry - good work, all!!! (I hope KayJones posts her Ipomoea coccinea photo in the PDB; it's a much better shot than the one I found when I was trying to help busybee with this plant...)
