 looks like a stalk. The root is thick and woody and the cap- 

 sule is egg-shaped and ribbed, with no stem. There is a patch 

 of these wonderful flowers in the Grand Canyon on Bright 

 Angel trail, halfway between the rim and the plateau, 

 where in a shaded spot beside a great rock the pure 

 t)lossoms seem to shed a moonlight radiance. They are 

 equally beautiful on the dry plains of Utah, where they 

 grow in quantities.
