Fringeleaf Wild Petunia

Found a pretty little wildflower, thought I'd identify it!

Only took me about 5 minutes to find an image that looked exactly like mine. In the website it's listed as petunia. Specifically Ruellia ciliosa. The common name is the Fringeleaf Wild Petunia.

For some reason, Duval is not listed. But it also says 'not vouchered', it does not say 'not present, proven' or anything similar.

Apparently ciliosa is a synonym for humilis. Seems legit.
