help identify this flower please

[changalvia]

So I was just wondering, could anybody help me identify this plant? It looks like passion flower, but I'm really not sure... Any help would be great

Doesnt look like passiflora at all to me but im certainly no expert. No idea what it could be. Why the particular interest in it, if I may ask? Can you share more or less your geographic location to help pinning down? Also other details on the plant, like is it a climbing vine, is it a bush, what kind of microclimate is it growing in, is it cultivated or wild, etc ?

Found it in my friends yard, was hoping it would be passion flower (the red kind, like different species) but I guess now that I've spec'd it out more it isn't... :/ haha just hopeful thinking I guess thanks

These flowers are growing all over S.A, normal sunny skies and warm temperatures on average about 24 degrees Celsius, growing naturally in a backyard. Its more like a tree than a bush... But not huge

i have no clue what that is, but it definitely is not a passiflora.
passifloras as a general rule have ten petaled flowers, and they have a pretty unique stamen

Passiflora is a vine, so no... it is not that.

Break a stem and see if there is a milky sap in it. Yes? it is a Euphorbia species. A wild form of the much cultivated Poinsetta group of plants.
