Variety americanum is a variable taxon widely distributed in mountains and valleys of the western United States from the eastern slope of the Cascades and Sierra Nevada across the northern Great Basin to the central Rocky Mountains. Within some populations dominated by acaulescent forms, occasional short, caulescent individuals or even taller plants may occur. These approach var. coloradense in the Colorado Rockies and resemble var. scariosum in the valleys of Oregon. Short caulescent individuals within populations of var. coloradense and var. scariosum approach var. americanum. Although the extremes are strikingly different, the genetic differences are apparently slight. Acaulescent individuals from the San Francisco Peaks and White Mountains of Arizona are treated here as var. coloradense. In the mountains of Colorado putative hybrids have been documented between Cirsium scariosum var. americanum and C. canescens and between C. scariosum var. americanum and C. undulatum.

Cirsium scariosum is a widely distributed complex of intergrading races distributed from southwestern Canada to northwestern Mexico. These plants range from acaulescent rosettes with a tight cluster of sessile heads to tall, erect, unbranched plants, or moundlike, more or less openly branched herbs. Acaulescent and caulescent plants sometimes occur in the same population.

Cirsium scariosum is a widely distributed complex of intergrading races distributed from southwestern Canada to northwestern Mexico. These plants range from acaulescent rosettes with a tight cluster of sessile heads to tall, erect, unbranched plants, or moundlike, more or less openly branched herbs. Acaulescent and caulescent plants sometimes occur in the same population.
