Beautiful photographs.
I was fascinated at the 3rd one. I think we have a flower of the same variety, but it blooms in red and a pinkish tone.
I'll take a picture of one tomorrow to see. Pity I don't have a good camera to see the details of the petals. they are tiny and many.
This one youposted here looks amazing. It's like an explosion within the flower, like one of those light-speed effects in sci-fi movies.

PS. curiosty killed the cat. I can't wait until tomorrow
this is the flower we have in venezuela that looks like the one you posted here.
A variety of Saman (rain tree)

Tomorrow, I'll take a picture of a plant some blocks from where I live, anyway
