I thought this little plant (greatly enlarged in photo) was a Ptilimnium nuttallii -but it doesn't look like the pictures in the Plant Database. Any clues?
It's a wildflower growing in the front pasture. (Central Texas). Thanks for your help.

Response to this post was Prairie Bishop. I'm wondering if it's Mock Bishop's Weed.
Thanks for your time.

Providing a link so others can see the additional information you posted on the other thread.

Your description of the foliage would fit the Prairie better than the Mock.

Thank you!

The petals look to long and the wrong shape for that genus. Looks more like Daucus carota to me. Just a guess. I'm sure someone will pin it down.

The flowers look like:
White Lace Flower (Orlaya grandiflora)

Thanks Myriam. I quoted you in the Gardening for Butterflies forum. Gotta admit, your photo looks like it could be the answer to this mystery. I appreciate the help.

Yes, your flower looks so much more like Orlaya grandiflora that either of the others. But, I'm not sure about the foliage. As shown in the other picture you posted on the wildflower thread: http://garden.org/thread/view_...

I think it could be:
Cilantros (Coriandrum sativum)
The foliage and leaves are a match.

It's funny you should say that, Bonitin because that was my first thought. But then I couldn't see why it would be growing wild in Texas hill country. As a lover of coriander, I would love to find it growing wild!

That would make an easy identification by smelling.

Okay, ladies, it's time to blow the whistle and call in the guys wearing white coats. I have officially lost it! After reading the last two posts, I ran out to the vegetable garden where I grow cilantro. It has bolted with the warm weather, but I'm leaving it as many tiny bugs like the flowers. I looked at one of them closely, but it didn't have that pink stuff going on in the middle. (Of course, my eyes aren't that great anymore). So then I walked to the front pasture where I found the mystery plant, dug down through the bluebonnets until I discovered a "true" leaf. I crushed it - and eureka! It's cilantro!!!!!
So two questions:
1. Why does the flower look so much different? (soil?)
2. How in the world did it get all the way out to the front pasture???
And here I thought I had an exotic, one-of-a-kind wildflower.
I feel like such an idiot.

First of all, Yay mystery solved! Great work, Bonitin!

I don't know why the plants look so much different but I guess it could be the soil or it could be the plants in the pasture are more mature. I've noticed the white flowers turning a pink hue as they mature.

They were possibly dropped off in the pasture by birds that were eating the seeds from your garden.

Don't feel bad! It happens to the best of us... hum humm I know I've done it many times - trying to ID flowers that I have already in my personal plant list. It just happens!

Now lastly, I'm really jealous of your wild growing cilantro, I can hardly get it to grow at all! Wish you could send some of your luck my way.

In case you didn't notice - you can click on "Mark as solved" at the top of your first post, now that this one is solved.

Great job, Myriam!

That's funny!
But anyhow Coriander is a beautiful plant, I would be happy too if it wanted to grow for me, you're lucky to have it self set in the front pasture Charlotte.
Thanks for the Christine!

Thanks to ALL of you for your help.
Clicking solved now.
