Notes
| Seriously threatened by development and non-native plants. Substantial portions of populations have already been lost due to development; in serious decline. Determined to be genetically distinct. No reliable morphological characters exist to distinguish L. paynei from other lupines in the L. albifrons complex; it has been described as being more arborescent, but this character trait has not been substantiated by data. Not allopatric with related taxa, so geography alone cannot be used to determine its identity. Further study is needed to determine the relationship between L. paynei and other lupines in the L. albifrons complex, particularly with regards to its distribution and morphological distinction. See Bulletin of the Southern California Academy of Sciences 17(2):58-59 (1918) for original description, and Systematic Botany 36(2):362-370 (2011) for taxonomic treatment. |
