A REMARKABLE DAISY 325 



The Limnanthus Douglasii is a wild swamp 

 plant the flowers of which sometimes seem to 

 carpet the ground. The upright, bell-shaped 

 flowers are usually milk white. But I have 

 received specimens from the Sierras that were 

 yellow. 



The beard-tongue, a relative of digitalis, of 

 the species known as Pentstemon barbatus,, has 

 flowers that vary from scarlet to almost pure 

 yellow and white. 



The crimson Clarkia and the bluebell have 

 flowers the colors of which are indicated by their 

 respective names; but both on occasion produce 

 blossoms that are pure white. Everyone knows 

 that the heliotrope, the lilac, and the pansy, 

 among cultivated flowers, are often represented 

 by white forms and the pansy by all known 

 colors. The same is true of the Whitelavia, the 

 typical flowers of which are also blue, and of the 

 trailing myrtle, the characteristic blue flowers of 

 which are sometimes modified to crimson and to 

 white. 



The gillias may show in the same patch 

 flowers of the same species of the deepest crim- 

 son, others that are pale rosy crimson, yet others 

 that are pink, and pure white. 



These examples of variation in different 

 flowers of the same species may be supplemented
