Note: All of the references that I have checked indicate that P. pauciflorus rays are yellow with no mention of white. But the images from Val Verde County have white rays with just a tinge of yellow at the tips, and the image from Bastrop County has a mix of white and yellow rays. All have the characteristic dark bands on the anther tubes.
