WATER-LILIES 



in the young leaves of regia, and their upper 

 surfaces possess a very characteristic reddish- 

 purple colour, except for some thin lines 

 of bright green tissue bordering chiefly 

 the radial veins near the centre of the leaf. 

 In the young leaves of Cruziana this tissue 

 is of a dark red hue. 



There are also differences in the under- 

 surfaces of the leaves: those of the young 

 Cruziana being green v^ith an occasional 

 purple tinge, vphile those of the young regia 

 are a pronounced red-purple. During the 

 later development the leaves of regia have 

 a more robust appearance, though the for- 

 mation of the upstanding margins begins 

 earlier in the season with Cruziana. 



Even in our northern climate both species 

 produce fruit, which, attaining half the size 

 of a man's head, contains numerous seeds, 

 each about the size of a large pea and brown- 

 ish in colour. These ordinarily retail at 

 twenty-five cents apiece and may be obtained 

 from any reputable seed-house. They are 

 sent out in small glass tubes filled with water.
