8 GEOLOGICAL SUEVEY OF THE TERRITORIES. 



The upper part of the leaflets is narrowed into a point, and the borders 

 are serrate to the point. 



Ilex afeinis, sp. nov. Leaf coriaceous, broadly ovate, round cuiieate 

 to the base, (point destroyed,) with borders narrowly margined, dis- 

 tantly dentate. Secondary veins open, nearly i)erpendicnlar to the 

 medial nerve, curving near the borders, thiu tliough distinct. Areola- 

 tion and tertiary nervation like that of I. coriacea^ Chap., of Florida. 

 The fossil leaf differs from the living species by thinner, more open sec- 

 ondary veins, curving more gradually toward the borders, and by the 

 teeth, rather turned upward, and not spiny. The spines, however, 

 may have been destroyed by maceration. These differences are of not 

 much account, and both species are closely related, if not identical. 



Ilex stenophylla, Ung. The specimens represent the form figured 

 by Heer, Fl. Ter. Helv., PI. cxxii, Fig. 7. Leaf coriaceous, narrowly 

 ovate, lanceolate, obtusely i^ointed, with entire borders ; medial nerve 

 strong ; secondary veins thin, the inferior ones more oblique; areolation 

 same as in Heer's Fig. 7. AH the specimens of this species represent 

 large leaves, none of them as small as those figured by linger in the 

 Chloris, and by Heer, loc. dt, Figs. 8 and 8b. Except this, no point of 

 difference is remarked. 



Ceanothus cinnamomoides, Lsqx. Same form as described in Re- 

 port, p. 289. The teeth are more sharply marked than in the first speci- 

 mens examined. 



Ehus acuminata, sp. nov. A single leaf, ovate in outline, narrowed 

 by an inward curve to a short, flat petiole, abruptly acuminate, with 

 borders irregularly crenulate-lobed. Secondary veins open, strong, 

 branching near the point, mostly craspedodrome in the lower part of the 

 leaf, while in the upper part some abruptly curve near the borders and 

 run along them. By its nervation, the species is like B. Pyrrhcv, Ung., 

 except that the secondary veins are more numerous, in our specimen 

 nearly as close to each other as in E. Meriani, Heer. It is distantly 

 related to our living B. aromatiGa^ Ait. 



eluGLANS SCHIMPERT, sp. iiov. A vcry fine species, represented by a 

 number of specimens, all with the same characters. Leaves of a somewhat 

 thick, but not coriaceous texture, lancealate in outline, entire, largest 

 near the base, about L]- inches broad, hence gradually tapering upward 

 into a long acute point, abruptly rounded downward to tliepetiole 5 whole 

 lenuth of the leaves about 6 inches ; from the broadest part to the point 

 4^ inches. It is comparable to some forms of J. rugosa, Lsqx., but the 

 form of the leaves, gradually decreasing to a point, is different, as also 

 the nervation, which, like the a];eolation, is more distinct. The medial 

 nerve is flat or grooved ; the secondary veins more oblique, (angle of 

 divergence, 42° to 45°,) more numerous and close to each other, 10 to 18 

 pairs in each leaf, curving slightly in ascending, and still more in com- 

 ing to the borders, which they closely follow in their ultimate divisions. 

 JuCtLANs acuminata, Heer (?). The same leaf, in all its characters, 

 as the one figured in Fl. Ter. Helv., PI. cxxix. Fig. 6, and which is 

 apparently far different from any other form of this species. Professor 

 Heer, in his description, has no remarks about this peculiar form: 

 rather comparable to J. costata, Ung,, as figured by Ludwig in Pal., 

 Vol. VIII, PI. Ivii, Fig. 7, and PI. Ivi, Fig. 7. In all the specimens of 

 this locality, there is no leaf referable to J. acuminata, Heer, or to its 

 relative, J. rugosa, Lsqx. 



JuGLANS DENTICULATA, Heer, (!) Fl. Arc, 2, p. 483, PL Ivi, Figs. 

 (3-9. In describing this species, the author remarks that it is like </. Bili- 

 nica, Ung., with more delicate teeth and secondary veins curving nearer
