Urban Weed to a Floral Garden

I was able to find an Urban Weed which could be a good candidate as a component of a Floral Garden. It grows just around the corner without cultivation. It flowers but there is much after this. As of this moment I have a photo of this urban weed. 

Close-up of the Flowers. 

For the meantime, identify the common name and the scientific name of this plant.

Flowers are transformed into berry forms. 

```7/6/2015 This is identified as Rivina humilis  belonging to  Family Rivinaceae but usually placed under Phytolaccaceae. Thanks to Dr. Walter Judd for the information. 

We will have to know of how this plant was documented in the Philippines just to get to its historical roots.  In fact this is already an ornamental plant in some countries.
