46 FLORA OF THE MONTANA FORMATION. 
side. It was, with little doubt, strongly palmately three-nerved as well 
as three-lobed. It appears unlike any form before reported from these 
beds. 
Habitat. — Point of Rocks, Wyoming, north of station and midway of 
cliff. Collected by Lester F. Ward, September 3, 1881. 
FlCUS INCOMPLETA n. Sp. 
PI. IX, fig. 2. 
Leaf large, thick, palmately three-lobed (?), lateral lobes small, ob- 
tuse; terminal lobe large, rounded; base?; midrib thickish, straight; 
palmately three-nerved ( ?), lateral secondaries ( ?) ; secondaries in upper 
portion of leaf distant, alternate, camptodrome, arching up and join- 
ing ones next above, producing large, irreglarly quadrangular areas; 
arching in small loops inside the margin ; nervilles irregular, mostly 
broken. 
The small fragment figured is all that was obtained of this form. 
It is really insufficient for proper characterization, but it appears un- 
like any form before reported, unless it be the upper portion of a leai 
of Dombeyopsis trivialis Lx., 1 and is perhaps best described tentatively 
as new. If the whole leaf were preserved, it might be shown to belong 
to some known species. 
Habitat. — Point of Bocks, Wyoming, north of station and midway of 
cliff. Collected by Lester F. Ward, September 3, 1881. 
FlCUS PROBLEMATICA n. Sp. 
PL IX, fig. 3. 
Leaf large, thick, palmately five-nerved, heart-shaped at base; mar- 
gin with scattered obtuse teeth; central nerve or midrib straight, very 
thick; next pair of nerves also very thick, arching around; outer pair 
thinner, emerging at right angles to the midrib, curving slightly up- 
ward and each entering a lobe; midrib with scattered thick secondaries 
at right angles; inner pair of nerves with secondaries on the outside at 
right angles to the midrib, and again branching near the margin, some 
of the branches entering the lobes; nervilles numerous, thin, broken; 
finer nervation irregular, producing peculiar irregular areolation. 
The fragment figured is the only portion of this leaf preserved, and 
could hardly be sufficient for characterization if it were not particu- 
larly well marked. It must have been a large leaf, at least 12 cm. 
broad. It has a broad, heart-shaped base and a few remote, obtuse 
teeth. It is strongly three-nerved, with the lowest pair of secondaries 
coming out at a point so near the ])etiole as to become practically five- 
nerved. The three middle nerves are very strong, with branches at 
right angles to the midrib.
