Extreme forms of the varieties of Saussurea angustifolia are distinctive, ranging from slender, erect, subglabrous specimens of var. angustifolia to dwarf, densely pubescent forms of vars. viscida and yukonensis. The extremes are connected by intermediates. As is indicated by the synonymy, little unanimity exists in the interpretation of these taxa. I have chosen to follow S. L.

Extreme forms of the varieties of Saussurea angustifolia are distinctive, ranging from slender, erect, subglabrous specimens of var. angustifolia to dwarf, densely pubescent forms of vars. viscida and yukonensis. The extremes are connected by intermediates. As is indicated by the synonymy, little unanimity exists in the interpretation of these taxa. I have chosen to follow S. L. Welsh (1974) in treating S. densa as a variety of S. angustifolia rather than as a distinct species. The extent to which the differences among these taxa are genetic or environmentally induced has not been investigated.
