the canescence does not extend to the leaves and flowers. 

 The species was originally collected on the side of a bluff 

 near the San Juan River in Utah, not far from the Col- 

 orado boundary (Proc. Am. Acad., xi, 73). The variety 

 comes from the same region and specimens were col- 

 lected at the head of the canons branching into the San 

 Juan and in Willow Creek Canon.
