Variety gracilior was described by A. Cronquist (1947) as 'plants slender, the larger stems either not more than 1.5 mm thick near the base or bearing fewer than 5 heads.' Such plants occur mostly in the southern part of the variety´s range (mostly Idaho and Oregon, some in Washington); while the gracile tendency seems real, many arbitrary identifications must be made if two taxa are recognized.
