DESCRIPTION OF SPECIES— MORIOtE. 197 



pi. xxiv, fig. 4, and |>1. Ixiii, fiir. !'. i>s also the close, oblique nervilles, are proper 

 to this genus. Tlie reference oi" these leaves to Ficiis, or to a genus of the 

 same family, seen/s eontinned by their affinity to Arfocarpoidcs pouroumce- 

 fonnis. Sap. (Fi. Foss. de Sez., p. 357, pi. vi, fig. 7), which they closely 

 •resemble, and which was formerly described as a Carpinus by Watelet on 

 account of its peculiar nervation. 

 Habitat. — Golden, Coloi-ado.

I'late XXXV, Figs. 1, 1«, 2. 

 ficus almifolia, Lesqx., Auuual Report, 1871, Supplement, p. 14. 



Leaves large, coriaceous, very entire, broadly ovate, obtuse, rounded, and declining at the base to 

 a thick booked petiole; middle nerve thick, channeled ; lateral nerves close, parallel, caniptodroree. 



These leaves evidently pertain to a ditferent species, though having some 

 of the characters of the former. The middle nerve is, at least, twice as thick, 

 as also the more distant lateral ones; the petiole, equally much stronger, is 

 shorter and hooked, and the leaves as seen in fig. 1 are obtuse. The nervilles, 

 though stronger, are slightly oblique to the secondary nerves, and of the same 

 type as in the former species. The specimen in 1 a is from a difi'erent 

 locality, Init by the form of the leaf and its very thick nerve it seems refer- 

 able to this species. Its relation to fossil congeners is apparently to the" 

 Protq/ici/s of the Eocene of St'zanne, like P. insignis, Sap. It has a more 

 distant affinity to Ficus? borcalis, Heer, of the Baltic Miocene Flora. 



Habitat. — Carbon, Wyoming; the specimens of figs. 1 and 2. 1 found 

 these two specimens only in the shale above the main coal. The fragment 

 of fig. 3 is from the Raton Mountains, New Mexico, in shale intermediate 

 to the lower beds of lignite (Dr. F. V. Hayden). There are some other 

 fragments of the same locality, all representing merely the basilar part of 

 the leaves. I have recently received a fine specimen of this species, sent by 

 Mr. Geo. Haddcn, from Coal Creek, Colorado. 



The name Ficus ulmifolia is necessarily changed, being preoccupied.

 Ficufi Basdc.nii, Lesqx., Annual Report, 1872, p. ;!94. — Schp., Pal. V6g6t., iii, p. .')95. 



Leaves subcoriaceous, entire, enlarged downward, rounded and truncate to a long petiole, taper- 

 ing upward to a long, twisted acumen ; secondary nerves thin, curved in passing to the borders, campto- 

 drome. 



This leaf seems referable to Ficus on acx'ount of its long twisted point, 

 which, like the general form, is related to F. appendicalata, Heer (Fl. Tert.
