tioned, both of the form gathered by Nuttall, with the leaves only 

 about half an inch long and scarcely a line wide, and of a luxuriant 

 form, with larger leaves, and flowers three fourths of an inch long 

 on longer pedicels. The leaves on decumbent branches are all 

 turned to the upper side, and often falcate, while the peduncles are 

 rigidly turned to the lower side of the branch. The species is a well- 

 marked one, and the most dwarf of the genus.
