Expansion of the Taxonomic Parameters
Hybridization with in the Balsamorhiza between Artorhiza non Artorhiza concept requires a reassessment of the survey parameters. The hybridization between B. sagittata and B. hookeri and between B. hookeri and B. hispidula and the occurrence of the low pinnate leaf taxa requires. This and the common chromosome count establish a reasonable basis for reviewing the larger taxonomic group.
