The fruit of this plant in Washington is commonly yellow, but near Ellensburg forms 

 with yellow, red, and black fruits occur growing together. Excepting for this character 

 they appear indistinguishable.

The types of gordonianus and lewisii are the same as to style character. Relying upon 

 this as a better character than leaf pubescence, I proposed P. confusus. Upon further 

 study however, I am convinced that the leaf characters, including pubescence, separate 

 the two species more truly than does the style character.
