GEOLOGICAL SUEVEY OF THE TERRITORIES. 379 



FiCUS SPECTABILIS, SJh nOV. 



Leaves large, coriaceous, entire, broacllj- ovate-lanceolate, contracted 

 to a short point, round truncate to the petiole, piunately nerved, the 

 lowest pair of secondary veins opposite from the base, branching out- 

 side, the upper ones mostly simple, parallel, irregular in distance, 

 oblique, camptodrorae. 



The leaf, an entire one, is 15 cent, long, 8 ceut. broad in its widest 

 diameter below the middle, equilateral. The first pair of secondary 

 veins is basilar and branched; the others, though i)arallel, are at irregu- 

 lar distances, all curving along the borders and anastomosing with ter- 

 tiary veins or fibrilise. Allied to Ficus IScliimfpex.i^ Lsqx., of the Mississippi 

 Eocene, it differs by its coriaceous substance, by the basilar veins going 

 out from the top of the i^etiole, by the somewhat abruptly-contracted 

 (not tapering) point, &c. With an entire leaf, the collection has a 

 number of fragments of this fine species. 



PiCUS AURICULATA, S]). noV. 



Leaves membranaceous, entire, smooth, ovate-lanceolate, taper- 

 pointed, rounded to the base into two auricles joined at the borders 

 below the top of the petiole, innnately nerved; the lower pairs of sec- 

 ondary veins opposite from the base of the leaf, the upper ones parallel, 

 alternate, camptodrome. 



The leaf described is perfect and its nervation distinct. Three pairs 

 of veinlets curve downward from the top of the petiole, passing in 

 curves to the borders of the auricles. All the secondary veins are more 

 or less branching downwards, curving along and following the borders 

 in anastomosing with divisions of the superior ones. Fibrilise distinct., 

 nearly continuous ; the leaf, 10 cent, long, has, besides the basilar vein 

 lets, ten pairs of secondary veins. It is somewhat unequilateral. 



Platantjs Eatnoldsii, E"ewb. 



Is represented by splendid specimens, but none as entire as the one 

 described by the author, Extinct Fl. of N. Am., p. 69. 



Platanus Haydenii, Newb. 



Most common at Golden. The leaves are still larger than marked by 

 the author, some of them preserved entire. 



BEivZom ANTIQUUM (?), Heer, Fl. Ter. Helv., II, p. 81, PI. xc. Figs. 1-8. 



Leaf oval, obtuse, entire, narrowed to a broad petiole, pinnately 

 nerved, lowest pair of secondary veins opposite, joining the medial nerve 

 at a distance above the base ; the others alternate, all thin and at an 

 acute angle of divergence. 



A single leaf, doubtfully referred to this species on account of obsolete 

 details of nervation. The surface of the leaves is punctate asin Benzoin 

 attemiatum, Heer, (loc. cit., Fig. 10;) but the form of the leaf and the 

 secondary veins are like Fig. 6, of B. antiquum. ' 



CiNNAMOMUM RosSMASSLEEi, Heer, Fl. Tert. Helv., II, p. 84, PI., xcii. 



Figs. 15-16. 



The leaves representing this species have the form and size of those 

 loc. cit, Fig. 2, with numerous straight, strong nervilles, perpendicu-
