 rigid bracts, and the almost smooth leaves have strongly revolute thickened 

 margins. 



1. B. empetriformis, Gray. A span or more high: pedicels some-

 to the sinuses. 



1. K. glauca, Ait. Shrub 1 or 2 feet high, glabrous, mostly glaucous, 

 branchlets 2-edged : leaves all opposite or rarely in threes, almost sessile, ob- 

 long or linear-oblong, or appearing narrower by the usual strong revolution 

 of the edges, glaucous-white beneath : flowers in spring in a simple terminal 

 umbel or corymb, lilac-purple, ^ to | inch in diameter. — Bogs, Colorado 

 and northward, thence eastward across the continent. The forms extending 

 southward into the Colorado mountains are depauperate alpine forms a span 

 high and with leaves barely £ inch long (var. microphylla, Hook.). 



6. LEDUM, L. Labrador Tea.
