refer to the fact that the plant comes from the late Mesozoic, 
and also to its occurrence in that middle period of time, between 
the typical Mesozoic and the dawn of the Tertiary, represented 
by the Laramie and other formations. 
A similar pod, possibly also a Robinia, has been described by 
Knowlton from the Yellowstone as Acacia lamarensis. The chief 
difference is that in the Laramie plant the seeds are placed very 
obliquely in the pod. 
Leucaena coloradensis Cockerell 
A very good pod of this species, containing a number of seeds, 
was found by Mr. Geo. N. Rohwer at station 17 in the Miocene 
shales of Florissant. The seeds are obliquely placed, exactly 
as in the living L. Greggii Watson, and are about 6 mm. long and 
4-33 broad; their apices are about 2 mm. distant from the opposite 
margin of the pod.
