Unabridged Note: From Reveal 2009 FNANM 8:276: "This species is known universally as Dodecatheon jeffreyi, although it was named a year earlier as D. jeffreyanum K. Koch. To avoid the introduction of a name that has never been used for this widespread and sometimes cultivated plant, D. jeffreyanum has been proposed for rejection (J.F. Veldkamp et al. 2008) [J.F. Veldkamp, J.L. Reveal, and K.N. Gandhi 2008 Taxon 57:1004--1006]".
