 core, and bearing a long recurved awn behind. Pod ovoid or globular, 4-5- 

 celled, 4 - 5-valved ; the valves 2-cleft : placentae many-seeded, pendulous from 

 the summit of the columella. Seeds smooth and wingless. Small, arctic or 

 alpine evergreen plants, resembling Club-Mosses or Heaths. Flowers solitary, 

 nodding on slender erect peduncles, white or rose-color. (Cassiope was the
