SCIENTIFIC EXPEDITION TO NORTHWESTERN COLORADO 151 



Riland, who found it on the bluff north of Meeker. It is probably from a 



slightly lower horizon. 

 Ficus speciosissima Ward. Showing the base very well. 

 Ficus planicostata Lx. Good material. 

 3. From East of Blythe's house; collected by Terry Duce. 



Geinitzia reichenbachi (Gein.) H. and J. A fragment of foliage which might well 



belong here. This is in the sandstone, and belongs to a lower horizon than the 



others. 

 There are also a few other imperfectly preserved species which I hesitate to 



identify.
