Hidden Flower, Thicksepal Catseye (Cryptantha crassisepala)
There are many species of Cryptantha. My identification to the species level is bolstered by Littlefield and Burns' inclusion of C. crassisepala in their book and by the fact that similar-looking species apparently don't extend into the Albuquerque area. By the way, that brown stain on my index finger is due to having accidentally crushed aphids earlier in the morning.
Livermore Stickseed (Hackelia pinetorum)
Phlox or Bindweed Heliotrope (Heliotropium convolvulaceum)
Given this plant's five-part but continuous flower, it would be easy (if incorrect) to assume that it's part of the Morning Glory Family. The white flowers are smaller than Bindweed flowers, and the leaves look hairy to the naked eye. The plant can be sprawling or a low bush. Look for Phlox Heliotropes in sandy areas.
Franciscan Bluebells (Mertensia franciscana)
As these photos show, Franciscan Bluebells range from pale blue to white. In the latter case, if you check other blossoms in the same patch you're likely to see hints of blue.
