I'm amazed and pleased that one of those pictures raised some interest.
That fruiting plant was photographed near/in Big Bend National Park, on a visit there in mid November 2014. That image time was 6:05 pm, so we were about a half hour away from Chisos Mountain Lodge where we stayed in the park.
Obviously not a labeled plant, it was eye catching from the road due to the dark green leaves and bright fruit in an otherwise generally muted fall xeric landscape.
I have two other images of the plant. I will fall into the Sumac relative camp, due to the compound foliage, terminal (nibbled upon) fruit clusters, and some obvious hairiness upon inspection of the one closeup image.
