Well, I guess Winged Sumac isn't right because the flowers on your plant appear to be white and the winged sumac has yellow blooms but the Prairie Flameleaf Sumac (Rhus lanceolata) looks to have white blooms. Here's a couple more links with photos:

I hope others (especially those from that part of Texas) will see this and pop in soon with some suggestions because I'm probably way off!
