48 FLORA OF THE MONTANA FORMATION. 
FlOTJS MONTANA 11. Sp. 
PI. XI, figs. 2, 3; PI. XII, fig. 1. 
Leaves thick in texture, broadly ovate, entire, slightly decurrent onto 
the petiole; palmately three-nerved from a little above the base of the 
lamina; midrib thick, flexuous; lateral nerves as thick as midrib, at an 
angle of 50°, with numerous irregular camptodrome branches on the 
outside, which arch just inside the margin or join one another, or again 
branch on the lower or outer side; occasionally with a strong second- 
ary so low as to make the leaf appear four- or five-nerved; upper 
secondaries, three or four pairs, alternate, at the same angle as the lat- 
eral nerves, frequently branched; nervilles strong, approximately at 
right angles to the secondaries, some percurrent, but many are branched 
or broken ; finer nervation produced by branches between and at right 
angles to the nervilles. 
None of the specimens referred to this species are preserved entire. 
They appear to be broadly ovate in outline, with perfectly entire mar- 
gins. They must have been at least 10 cm. long and from 5 to 6 cm. 
wide. The petiole is preserved in two specimens, the longest being 
1 cm. in length. 
This species appears to be allied to Fieus planicostata Lx., 1 which dif- 
fers from it in being rounded at base, and with the three principal 
nerves arising at the base of the lamina, instead of above. The sec- 
ondaries, especially the upper ones, are not so much branched as in the 
one under discussion. 
Habitat. — Point of Rocks, Wyoming, north of station and midway of 
cliff. Collected by Lester F. Ward, September 3, 1881. 
Ficus Wardii n. sp. 
PI. IX, fig. 1. 
Leaf of firm texture, gracefully oval in outline, perfectly entire, 
slightly heart-shaped at base; palmately five-nerved from the base, 
camptodrome; lateral nerve with about eight secondaries on the out- 
side, all arching inside the border and joining; next pair of nerves 
with few strong secondaries in the upper portion, on the outside; 
central nerve or midrib, so far as can be made out, without secondaries; 
nervilles mainly forking. 
This fine leaf, which unfortunately is the only one observed, is 6.5 
cm. broad and must have been about 8 or 10 cm. long, the upper por- 
tion being destroyed. It was probably oval, or possibly more nearly 
round, in outline, with a slightly heart-shaped base. It is equally five- 
nerved from the base, the lateral, or outside nerves, with eight or 
more secondaries on the outside, the next or inner pair with several
