White to Green and Brown Flowers 117 



with vivid rose pink, that have a peculiar bunch of tiny 

 narrow leaves set just where the little stems of the indi- 

 vidual flower-umbels spring from the top of the main stalk. 



It is also a most fascinating plant, both by reason of the 

 fact that its fine cream and rose blossoms grow in barren 

 localities, and also because its leaves (which are green above 

 and silvery beneath) grow near to the ground, on slender, 

 branching, woody stems, while the flower-stalks are ex- 

 tremely long, often reaching a height of over twelve inches. 



Eriogonum ovalifoliuni, or Silvery Eriogonum, is a 

 densely woolly and silvery plant with very short stems and 

 oval leaves crowded on the numerous branches. The flow- 

 ers are yellowish-white, tinged with rose-colour, and grow 

 in a single head on each stalk. 



Eriogonum androsaceuvn, or Dwarf Eriogonum, is the 

 alpine species, and almost an exact reproduction in minia- 

 ture of its " Tall " relation. The chief difference between 

 the two plants is that the Dwarf Eriogonum is more hairy 

 and woolly, and generally has cream-coloured flowers with- 

 out any tingeing of pink. It only grows about three inches 

 high, and is found at 7,500 feet.
