Discussion

A tomentose entity that was recognized as Haplopappus greenei subsp. mollis differs also in other ways from typical Ericameria greenei. It may merit recognition at some level. A biosystematic and population-level investigation of this complex is needed to better understand the causes and significance of such variation.
