Dives silica which from their more recent omee are referable to 
the Upper Miocene. Among species of Salix, Myrica, , an 
hus, whose representatives are intimately relate to species of 
our time, the fossil flora of Green River has an Ampelopsis and a 
Morus which b y their marked affinity natin in the Tertiary the 
origin of our now so predominant and widely distributed Vir- 
ginian Creeper and Red Mulberry.
