GEOGKAPHICAL DISTEIBUTION 9 



tween lily species that are widely separated 

 geographically. "What L. philadelpMcum is to 

 America, for example, L. elegans and L. dauri- 

 cum are to Asia and L. croceum is to Europe. 

 Again, the L. superhum of the eastern United 

 States differs immaterially from the western 

 L. pardalinum, while L. Hansoni might he called 

 an Asiatic counterpart and L. Janhae a Jjuro- 

 pean one. Then there are the American L. 

 canadense and L. maritimum, the Asiatic L.

 put another lily girdle around the earth. 

 Finally, L. Washingtonianum on this side of 

 the Pacific, must be distantly related to the 

 white and whitish trumpet lilies of the other 

 side. 



It is probable that there remain no undis- 

 covered lilies. The only hope of any new spe- 

 cies seems to be China — now the world's great 

 botanical reserve and the lure of the most 

 ardent inland voyages of discovery. 



Just when the lily map was changed by the 

 entry of this flower into garden cultivation it 

 is impossible to say; doubtless the earliest 

 movement from the wild is lost in antiquity. 

 However, it is going far enough back into the
