Anza-Borrego Desert Wildflowers

This cluster of tiny wildflowers is typical of the flowers in Plum Canyon in Anza-Borrego Desert this spring. Because of the dry and harsh environment, most of the flowers are tiny like the three in this photo. But what they lack in size, they make up for in color. It's pretty difficult to try and identify all these flowers, but I'm pretty sure the white one is Desert Pincushion and the tiny lavender-colored flower is Gilia. There are so many flowers that the yellow ones could be that I don't want to hazard a guess. Help out if you can.
