Please can you add a really clear image of a single flower. I think it is in Melastomataceae. But cannot see enough detail to try and go further. melastomataceae - Google Search
It reminds me of something in Onagraceae, perhaps Epilobium? Leaf venation doesn't look quite right for Melastomataceae.
Pitters image looks to me like a woody shrub. I thought it might be Centradenia floribunda but am not sure. The crescent shape stigma/style is very typical of Melastomataceae but I am not sure if I am seeing that...hence request for clear close ups.

Yes it is woody, I should have mentioned that. Here is another photo of the flower. I hope it is more helpful.
Thank you. I think I am warm..even the leaves seem a good match. Maybe some one else can help. However Melastomaceae is a rather large family and I am not 100% positive. I am sure it is not Epilobium. Centradenia floribunda - Google Search: Centradenia floribunda leaves - Google Search: Centradenia floribunda flowers - Google Search: Several images here...
