Variety majus is widespread and common in the Rocky Mountains. These plants are often locally common in Idaho and northern Utah, but they are rather rare in the Cascade Range of Washington. The high-elevation plants in Washington are often markedly different from similarly situated Rocky Mountain plants, having smaller leaves and flowers, and tighter, more compact, umbellate inflorescences.
Variety majus is distinct from and often grows with </i>var.<i> umbellatum in Colorado, leading many local taxonomists to distinguish the two at species rank. In Wyoming and Montana, however, </i>var.<i> majus occasionally is difficult to differentiate from </i>var.<i> dichrocephalum. Variety majus often occurs with Eriogonum heracleoides, and mixed collections occasionally are encountered. Care must be taken in the herbarium to differentiate the narrow-leaved E. heracleoides var. leucophaeum from the broader-leaved E. umbellatum var. majus, although the two do not grow together.
