12 FLORA OF THE MONTANA FORMATION. 
pairs, subopposite, arching upward for some distance; remainder of 
nervation not preserved. 
This species is represented by the single specimen figured. Its length 
is about 4 cm. and its width a little more than 1 cm. It is with some 
hesitation that I refer this to Quercus, for it is very fragmentary and 
has little of the nervation i)reserved. It has, however, a resemblance to 
certain forms that have been so referred, and I therefore venture to 
place it as above indicated. It is hardly possible to make any com- 
parisons between this and known forms that will be of value. 
Habitat. — Right bank of Missouri River, 7 miles below the Coal 
Banks. Collected by Lester F. Ward, August 24, 1883. 
FlCUS MISSOUR1ENSIS 11. Sp. 
PI. 1, fig. 5. 
Leaf thick, elliptical in outline, slightly inequilateral, apparently 
broadest at or a little above the middle, rounded rather abruptly below, 
apex not preserved; midrib very thick, straight; secondaries very 
numerous, thin, emerging at an obtuse angle, camptodrome, anastomos- 
ing well inside the margins with the secondary next above; interme- 
diate secondaries numerous, passing nearly or quite half the distance 
to the margin, then vanishing; other nervation not preserved. 
This leaf is not well preserved, lacking probably the upper third. 
The part remaining is about 6 cm. in length; the complete leaf was 
probably about 8.5 cm. in length. The width is 3.75 cm. This species 
is evidently allied to Ficus glascceana Lx., 1 from the Dakota group of 
Kansas. The Kansas species is, however, three times the size, is broadest 
below the middle, and has the close parallel secondaries at a more acute 
angle. In general appearance these leaves are very similar, and the 
Montana species may well have been the modified descendant of the 
Dakota group species. It appears to be quite unlike anything hereto- 
fore reported from the Belly River or allied beds.

JUGKLANS ? MISSOURIENSIS 11. Sp. 
PI. I, figs. 7-9. 
Leaflets membranaceous, broadly elliptical-lanceolate in outline, 
inequilateral, base not preserved, narrowed above into an acuminate 
apex; margin entire or very slightly undulate; midrib very thin, liex- 
uose; secondaries numerous, alternate or subopposite, curved upward, 
camptodrome, anastomosing by a series of small loops with the one 
next above; other nervation not preserved. 
The three leaflets referred to this species unfortunately all lack the 
lower portion. They all have the same shape and nervation, and prob- 
ably are correctly placed together. As nearly as can be made out, they
