Discussion

Of conservation concern.

Variety patulum is found mainly in central and northern California in the Central Valley, on the inner coastal ranges, and on the western foothills of the Sierra Nevada. It is disjunct to the Santa Monica Mountains, Los Angeles County. It and the hansenii phase of Dodecatheon hendersonii can be difficult to differentiate in the northern Sierra Nevada. Usually, the anthers of var. patulum are much shorter than those of D. hendersonii. Furthermore, the connective of var. patulum tends to be broadly triangular and heavily rugose; that of D. hendersonii is narrower, longer, and decidedly less rugose.
