The following six species are not now found growing in peninsular 



Florida : 



Leitneria floridana ( ?) Vitis sp. 



Quercus chapmani ( ?) Benzoin cf. melissaefolium 



Brasenia purpurea Viburnum cf. dentatum 



Of these Leitneria floridana is a very local form not found nearer 

 than the Apalachicola River, and the chief center of growth of 

 Quercus chapmani is also in west Florida, while the true Viburnum 

 dentatum does not occur nearer than the upland region of 

 Georgia. 



Finally, the Vero deposits have yielded a fruit probably identical 

 with similar remains from the late Pleistocene of New Jersey 

 representing an entirely extinct species of Zizyphus, a genus 

 abundant in Southeastern North America during the Tertiary, 

 but not now represented except by a single species of the arid south- 

 west (Texas to Arizona). 



Two of the fossil species have been recorded from the Pliocene. 

 These are Taxodium distichum and Magnolia virginiana. One, 

 Quercus virginiana, is found in the early Pleistocene of both Ken- 

 tucky and Alabama, and the following occur in the late Pleistocene: 



Pinus taeda Acer rubrum 



Taxodium distichum Zizyphus sp. 



Quercus virginiana Viburnum nudum 

 Brasenia purpurea 



These latter, while they constitute but 26 per cent of the known 

 fossil flora at Vero, are especially significant in connection with the 

 fact that they all occur elsewhere in the physiographically youngest 

 of the Pleistocene terrace deposits, namely, the Talbot of New 

 Jersey and Maryland, the Chowan of North Carolina, and the 

 corresponding lowest terrace at several localities in Alabama, while 

 the Vero deposits constitute the youngest physiographic terrace 

 plain of the region and are referred to the Pensacola terrace by 

 Matson. 1 



In my judgment and in the ordinary acceptance of that term 

 this flora is unquestionably of late Pleistocene age.
