 around, for propagation, and for the smaller aquatics. 



The Victoria Regia has in 1911 probably broken the record in 

 Europe for the quantity of flowers produced in the one year, for 

 although in their native home in the Amazons these most wonder-

 has been produced until, on December 11, the total of 54 was reached 

 from the one plant. The largest flower had a diameter of fifteen
