This one started making it's first appearance early in the Summer but has become prominent in September. As you travel the roads it's you can see it as a low growing bushy plant with lots of yellow flowers. It's hard to distinguish from the Lindheimer senna from a distance, which is also growing this time of the year.
Here's a shot of the whole plant, which unfortunately didn't come out real clear. As you can see it's growing right on the road.
