[explorer.natureserve.org] Taxonomy, Distribution, Habitat: In his 1994 Synonymized Checklist, Kartesz included glauca material in Claytonia rubra. In 1999, he moves glauca material into C. exigua and recognizes it as a subspecies, along with the taxon he called Claytonia spathulata in 1994 (=C. exigua ssp. exigua of Kartesz 1999).
Found from coastal California to extreme southwestern British Columbia in a variety of habitats including buffs, coastal sand dunes, and other open areas. Distribution is slightly more restricted to areas near the coast (and the Columbia River Gorge) than the typical ssp. but found in a range of habitats. (contributed by Mary Ann Machi)
