Thanks!
Wildflower in Big Bend National Park
Might be Jack-in-the-Pulpit, Arisaema triphyllum, sometimes called Indian turnip.
Might be a Centaurea sp.
Might be Zizia aptera.
Looks like some kind of dock, Rumex sp.
First one looks like chinaberry, Melia azedarach.
After looking at it again, might be sweetgum. The opposite arrangement I saw might be where a long petiole crossed a stem.
Looks like a maple. Sweetgum leaves are alternate, those look opposite.
#4 might be Smilax
First one could be Virginia creeper.
Looks like a Malvaceae.
Smilax sp.
Might be Campsis radicans.
