52 FLORA OF THE MONTANA FORMATION. 
Ehamnus goldianus Lx. l It has a slightly heart-shaped base, with a 
number of short tertiaries going out from the lower side of the first 
pair of secondaries, exactly as Lesquereux describes for R. goldianus, 
and quite unlike typical Ficus irregularis. The latter has a narrowed 
or wedge-shaped base, with no tertiaries on the lower side of the first 
pair of secondaries. 
Habitat. — Point of Bocks, Wyoming. Black Buttes, Wyoming. I 
Golden, Colorado. 
Ficus tili^efolia Al. Br. 
PI. XIII, fig. 1. 
This species is reported by Lesquereux from a large number of locali- 
ties, including in age the Montana formation, true Laramie, Denver, 
and Eocene or Miocene, and it can not therefore be regarded diagnostic 
of any formation. 
The recent collections contain a somewhat fragmentary leaf from 
Point of Pocks, Wyoming, which I refer with some hesitation to this 
species. It is very similar to a figure of Ficus tilicefolia given by Heer, 2 
except that it has slenderer intermediate secondaries and more irregu- 
lar areolation. It may represent a new species, but as it is quite imper- 
fect I have preferred to keep it under F. tiliarfolia rather than make 
it a supposed new species. 
Habitat. — Point of Pocks, Wyoming.? Golden, Colorado. Burns's 
ranch, Montana.

The collections from various localities contain a number of specimens 
that are referred with more or less hesitation to this species. They 
differ considerably in size, yet on the whole it seems best to place them 
under this species, at least until more complete material can be obtained.
