I have seen this little plant growing in several places in
Wayne County, Utah. It is fairly easy to find when it is
blooming. The ones I have seen are only about 4 inches tall,
but the flowers are about the size of a penny, and they show
up quite well.
I was told by a professional
botanist that this was a flax, but had never seen a picture
or description of it in a book until quite recently.
I first found it described in the book
"Desert Wildflowers of North America", by Ronald J. Taylor.
The range was said to be "from the Painted Desert through the
Sonoran Desert of Arizona and into the Chihuahuan Desert of
New Mexico and western Texas", which is far south of the area
where these were found (central Utah).
