 Llaiiy attempts have been laade to explain wliy the .-^one of 

 annuals is so similar along all beaches. One extreme theory is 

 that the striking similarity of ocean and lake beaches was caused 

 by the former salt condition of Lake lUchigan. Plants grew under 

 salt conditions and remained after these conditions disappeared. 



Warming's view is that a halophyte is essentially a xerop/h.yte. 

 Salicornia herbacea is the only one which will not grow away from 

 salt water.
