2 to 4 feet of water, or stray plants may be found in less than 2 feet. 

 Many of the floating leaves were 20 to 24 inches across and the 

 standing ones not much smaller. At Upper Sandusky Bay I 

 found a floating leaf 26 inches in diameter and another with a 

 petiole more than 5 feet in length. Both at Sandusky Bay and 

 along the Portage River the acreage of Nelumbium was greater 

 than at East Harbor, but nowhere did the plants present a more 

 vigorous growth or so magnificent an appearance. "

 flower has been shed the ends of the seeds are seen projecting from 

 these pockets. The form of the capsule awl the arraimviiieiit of
