These tiny magenta flowers show up in the spring at the ≈1200m level in the Mojave Desert, but ONLY if there has been adequate rain, in this case about 100mm or more. The flowers are ≈7mm in diameter.
First shot is what they look like from standing height with a 50mm lens. Next, a close shot at ≈ 1:2 RR. Finally, another angle showing an even smaller white flower nearby.
