the flowers that open only in the hot sunshine, after the 

 manner of their type, into the most lovely waxen blossoms, 

 ranging in tint from the purest white to a deep carmine 

 pink, set off by the centre of crimson stamens. 



The whole plant is sessile, the flowers resting upon the 

 ground, the leaves withering as the flowers come into 

 bloom, so that a colony of Lewisias appears on a clear 

 warm day like a myriad of tiny water lilies in clumps of 

 fives and sixes, scattered thickly over the arid bank. The 

 effect is indescribably beautiful, and the lover of flowers 

 feels a pang of compunction as he treads perforce upon 

 the perfect blooms. The only drawback is the want of 

 perfume, to make the Lewisia the veritable flower of 

 Paradise. 



The root of the Lewisia resembles a branching carrot in 

 form and colour, and contains a large amount of farina- 

 ceous nutriment of wholesome quality. It is, or was, 

 extensively used by the Indians of Oregon as food, under 

 the name of Spcetlum, much as the Camass and Wapatoe 

 of the lower coast lands. 



The plants have been brought without difficulty into 

 perfect bloom and ripened seed in New Westminster, and 

 roots sent to England have yielded a profusion of choicest 

 flowers.
