Yes, Rivina humilis (Rouge Plant), thanks! I guess it is the same as this specimen, just more verdant due to being shaded. Some report the berries are edible, others claim they are somewhat poisonous to humans...

Ah, Polygala alba (White Milkwort), I'll take it! Thanks!! B)

My guess is that it is Stenosiphon linifolius also known as False Guara. I have only seen it in the fall when it is STILL blooming but much tangier and tall. It is a sand out in the grasslands. I collected seed of it in September but the deer ate it. I have seen its growing at LBJ Wildflower Center.. Very cool plant. They are not a common plant in my corner of the hilcountry . Much more prevalent to the north of me..

I've seen this plant for the first time on July 29 2023 on the short of the Ashuapmushuan river north of Lac St-Jean, Quebec, Canada. Thanks Jekeesi for puting me on the yrack to identify that plant .
