 from our typical specimens in the spikes being much shorter and the 

 leaves more hairy.

Hab. From Nisqually to the Cascade Mountains ; also, a form of 

 it on the Upper Columbia and its tributaries. [The latter is de- 

 scribed as having long dense spikes of shortly pedicelled flowers, and

 not found in his herbarium.]

 Differs from L. leucophyllus chiefly in the more branching habit, 

 usually looser spikes, and distinctly pedicellate flowers. It may not 

 be specifically distinct.
