At the highest elevations of its growth, near or even above timber- 

 line, the branchlets become extremely short and rigid and here the 

 bushes grow close together in dense chaparral; it is this form that 

 has been described as R. Churchii; see Coville's note on the appear- 

 ance of this shrub near timber line in the Mineral King country. 50 

 Merriam 53 says that on Mt. Shasta it grows at the head of Panther 

 Creek near timber line and also much lower down.
