Discussion
Eschscholzia minutiflora is highly variable in flower size. Typically, plants are hexaploid (2n = 36) with petals 3-10 mm. Tetraploid plants (2n = 24) with petals 6-18 mm, from the northern and central Mojave Desert of California, have been distinguished as subsp. covillei. Diploid plants (2n = 12) with petals 10-26 mm, restricted to the El Paso and Rand mountains of the western Mojave Desert, have been distinguished as E. minutiflora subsp. twisselmannii and are considered to be of conservation concern; previously they were misattributed to E. parishii.
