Discussion

Of conservation concern.

Carlquistia muirii is known only from granitic substrates in the southern Sierra Nevada and Santa Lucia Range (Ventana Double Cone). Major disjunctions among the populations of C. muirii, a self-incompatible tarweed, may be explained by vicariance, ancient dispersal, or both (B. G. Baldwin and D. W. Kyhos 1990).
