It's certainly a flax. You say 'down the road' as if this might be in a location where people have been active rather than a really wild place. Could it possibly be a stray plant of common flax, Linum usitatissimum, which is a crop grown in Texas according a quick Google. Just a thought.

Thanks to everyone for the replies! After your suggestions and looking at other pics online, I'm pretty convinced that this is a Torilis arvensis, Common Hedge Parsley. Thank you again! Here is a link that might be useful: This is exactly what my plant looks like.

chervil2, Thanks for reminding me that I needed to mention that if you double click on the photo above it will take you to my on line photo album with many more photos to identify. Once you open the photo album if you click on the largest box in the right hand corner of the page the thumb nail photos will be displayed at a reasonable size or you might prefer to choose view by slide show on the top of the left hand side. Hope that's not too confusing. kt

The folks on the "Name That Plant" forum helped me identify all of them very quickly. For reference, they are: Crimson Clover (Trifolium incarnatum) - first 2 pics Blue-Eyed Grass (Sisyrinchium sp.) - 3rd Nuttallanthus sp. (probably texanus) - 4th Verbena sp. (probably V. canadensis) - 5th
