Can anyone help me find 5 wildflowers with the same genus?

I have a biology project that involves collecting and identifying 15 different kinds of wildflowers. I currently only have a few wildflowers collected and they’re all different genuses. So my question is where can I find flowers with the same genus?
I currently live in East Texas and I am trying to find flowers in that region, and today I am going to Tyler where I will probably look for flowers there.
So if anybody could please answer my question before I leave(I’m leaving in 2 hours), that would be super appreciated.
Oh and if you also could provide a link with pictures of the flowers, that would also be greatly appreciated.
