Hi Evan, Thanks for your note. You said, "Sida filicaulis as a synonym to Spreading Fanpetals (Sida abutifolia)". Since there isn't a photo to compare mine to, I'm asking for your help. This little plant grows all over my property in the hill country of central Texas. Enquist lists two in his book, Sida filicaulis (Sida procumbens) and Lindheimer's Sida (Sida Lindheimeri). The one in my pasture has the shorter leaves so I leaned toward filicaulis. Because I don't want to post a photo that's incorrect, would you please verify that this would qualify as an abutifolia. Thanks for your time.

Evan suggested that I post this here for help.

Here are some descriptions of the two plants.

One thing I read is Sida abutifolia is procumbent, laying on the ground, mat forming where S. lindheimeri is upright. Of the flower photos I found online your seem to more closely match S. abutifolia.

Can you show the whole plant, and close-up of leaves and stems?

Sida abutifolia ..

Spreading Sida can be found in grassy areas or bare caliche of the Edwards Plateau and South Texas Plains. It is a small, spreading perennial that can reach eighteen inches in length. The leaves are narrow, have a toothed margin and are 1/4 to 3/4 inch long. The yellow-orange flowers are approximately 1/4 to 1/2 inch in diameter and bloom from March to October. The leaves are occasionally eaten by white-tailed deer and cattle.

Sida lindheimeri is difficult to find photos of, those I found don't look to match

The leaf margins are closely serrated, yours are more open like S. abutifolia.

Thanks to everyone for your help. After looking at the numerous sites, I've concluded that what I have is the Sida abutifolia. It lays close to the ground. I appreciate the responses!
