The Claytonia lanceolata complex in California. In northern California, (A) Claytonia lanceolata Pursh on granite, (B) alternate-leaved and undescribed C. “serpenticola” on ultramafic rocks, and (C) an unrecognized taxon on greywacke that fits the description of C. obovata Rydb., unsampled in previous phylogenetic studies. In southern California, (D-H) The Claytonia “peirsonii” complex, with (D) var. “peirsonii” on granite in the San Gabriel Mountains near the type locality of C. lanceolata var. peirsonii Munz & Jtn. New discoveries in this complex within a species complex include (E) the long-petioled C. “peirsonii” var. “panamintense” in the Panamint Mountains on dolomite, (F) light pink-flowered var. “yorkii” on volcanic tuff in the southern Sierra Nevada, and two variants in the San Bernardino Mountains on (G) grey and (H) white dolomite at Furnace Canyon and Bertha Ridge, respectively.
