148 Rydberg : Rocky Mountain flora 



lower leaves petioled, 2-5 cm. long, finely cinereous-puberulent, 

 in age sparingly so ; blades spatulate or oblanceolate, entire or 

 sparingly dentate, thin ; upper leaves linear-oblanceolate or linear, 

 entire ; branches strongly ascending ; involucre turbinate, 8 mm. 

 high, 8-10 mm. broad ; bracts in 6 or 7 series, linear, acute ; green 

 tip short, glandular-puberulent, much shorter than the chartaceous 

 portion, only slightly squarrose ; rays rose-purple, about 8 mm. 

 long ; achenes finely strigose. 



This agrees fairly well with the description of M. laetevirens 

 Greene, except that the plant is evidently cinereous-puberulent.
