and specimens distributed under that name, but further study 

 has shown it to be distinct. That species is locally known only 

 from the mountains of southwestern Oregon. 



Wliile L. oreganus is related to L. miicronulatus and re- 

 sembles it considerably in leaf form, it is a plant of entirely dif- 

 ferent habit, being erect instead of decumbent, has longer stems, 

 a much longer raceme, has a notched instead of entire upper 

 calyx lip, and the keel is glabrous instead of ciliate above the 

 middle.
