taxodii). These galls are the result of some insect which lia- 

 modified the young cypress seed so that in the mature state 

 they bear no resemblance to naturally developed cypress seeds. 

 These galls are very often found closely packed in the cypress 

 cones. 



Three of such galls were collected, two being globose while 

 one was somewhat shriveled. In all three cases there is a minute 

 oval opening at one end. 



The fact that the glauconite bed is a reworked one excludes 

 any idea that the cypress swamp might be of Eocene age. This 

 is corroborated by the fact that Taxodium distichum has a 

 geological range from the Pliocene to recent. Along with this 

 bald cypress I found several insects galls, Retinodiplosis taxodii; 

 a grape seed, Vitis cordifolia; and numerous acorns and cups 

 of some undeterminable species of Quercus ; and also several 

 rhizomes of some unknown marsh plant. 



There have been many other discoveries of buried cypress 

 swamps very similar to this one, too many to list here, all of 

 which have been proven to be of Pleistocene age. Therefore it 

 is correct to assume that this deposit at Greenbury Point is of 

 Pleistocene age.
