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

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

 they appear indistinguishal^le.

 1896; Cape Horn, Piper 5031. 



Zonal distribution: Humid Transition. 



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. conjusus. Upon further 

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

 the two species more trul}' than does the style character.
