H.\B. On the declivities of low hills, and on the steep banlis of streams on the Mest side of the Rocky 

 Mountains. Douglas. — This is most allied to the following-; but abundantly distinguished by the truncate 

 base to the leaves, and the spicate panicle, by havin^ less oblique calyces, very short stamens, and by the 

 absence of petals.

 Douglas. Scouler. /3. Shady woods. Douglas.— I have quoted the Tiaretla Menziesii of Pursh, with a 

 mark of doubt, chiefly because he describes the«niceme filiformand spicate," which is'byno ™ea"s the case. 

 Ours is a remarkably distinct species.
