ultimate branchlets more or less flattened and pulverulent, all 
subtended by bract vestiges; flowers in small groups, the middle

This undershrub is always found in moist more or less stony 
soil of deeply shaded places near water courses from 500 to 2500 
feet elevation. 
Its low sparingly branched habit coupled with the erect 
pyramidal infrutescence serve to distinguish it at once.
