Dusk Bloom

I've spent the better part of the last three hours trying to work out which photo to post for Monday's. I have a billion things un-done and a billion more half-done, but oh well. Too late now!

A yellow flower after some rain, as dusk settled in:

When I stayed in Sydney, my friends took me to a few different places. One of those was an outdoors shopping complex that had some lovely big flowers in the garden there, and this is one of the photos I got of them. As always, any hints on what type of flower this is are welcome!
