Notes: Move to List 1B? Reduced by vernal pool habitat loss; threatened by vehicles, grazing, development, and agriculture. Taxonomic problems; distinguishing between this taxon and M. sessilis (= M. minimus ssp. apus var. sessiliflorus in A California Flora (1959) by P. Munz) is difficult; are both rare? Plants in the Central Valley that resemble this taxon may be hybrids between M. minimus and M. sessilis; see Flora of North America 3:136 and Evolution 13:151-174 (1959) for details. See M. minimus in TJM (1993); not in TJM 2. See Bulletin of the California Academy of Sciences 1:277 (1885) for original description, and Aliso 2(4):396 (1952) for revised nomenclature. |
