|discussion=<p>Oxalis californica is recognized by its caulescent habit, stems with reduced vestiture (glabrous or very sparsely short-puberulent), one (to three) flowers on long peduncles and pedicels, the yellow corollas often drying with a blue or purplish tinge, and relatively wide, glabrous, and usually purplish or pinkish tinged sepals.</p>
