« Britton and Shafer (North Am. Trees, 754, 1908) record Rhododendron californicum Hooker, as a small 

 tree. It occurs in the coast region from California to British Columbia. As I know this species it occa- 

 sionally reaches a height of 20 feet, or more, but the usual form of the stem is, in my judgment, like an over- 

 grown shrub.
