416 GEOLOGICAL SUEVEY OF THE TEREITORIES. 



dentate by three or four pointed or spinulose teeth on each side ; sec- 

 ondary veins opposite, craspedodrome, simple, passing up in a slight 

 curve to 'the iwint of the teeth. The identiticatiou of this leaf with 

 Heer's species, represented (Flor. Tert. Helv., Ill, p. 73, PI. cxxii, Fig. 24,) 

 b3^ still smaller leaves without any trace of nervation, is uncertain. 

 Habitat. — Middle Park, Dr. Hayden. 



Ilex subdenticulata, sp. nov. 



Leaves coriaceous, linear-lanceolate, acuminate? (point broken,) irreg- 

 ularly denticulate from the middle upward with small, sharp-pointed teeth; 

 penninerve ; lateral veins distant, opposite, curving up under an acute 

 angle of divergence from the middle nerve, and at a distance from the 

 borders, forming, by anastomose with the veins above, a double festoon 

 along the borders, and entering the teeth by outside, small branchlets. 

 This si>ecies is closely related to I. denticiilata, Heer, (Flor. Tert. Helv., 

 Ill, p. 72, PI. cxxii. Fig. 20,) differing, however, by the taper-pointed or 

 acuminate form of the leaf; the more numerous teeth descending lower on 

 the borders; the more distant and all opposite secondary veins, wkich 

 curve farther inside and at a more acute angle of divergence, &g. The 

 nervation is, however, of the same type. The same shale bears a small, 

 round, crushed fruit, representing, apparently, a pulpy berry, bearing 

 one or two ovate-pointed seeds siunlar to those of this genus. The berry 

 is 5 millimeters wide; the seeds 1^ millimeters broad near the rounded 

 base, and 3 millimeters long. 



Sahitat. — One mile west of Florisant, Colorado, Br. A. C. Feale. 



Ilex undulata, sp. nov. 



Leaf narrowly oblanceolate, pointed, tapering dowuAvard to a short 

 petiole ; borders undulate, obtusely deutate in the upper part of the 

 leaf, entire from the middle ; nervation of the same type as that, of the 

 former. It may represent a variety of the same species. 



Rabitat. — This specimen is without label; mixed with those of Middle 

 Park. 



Paliurus Florisanti, sp. nov. 



Leaf small, 2h centimeters long only and 1 centimeter broad, ovate- 

 pointed(!), (point broken,) rounded at the base to a short, tliick petiole, 

 slightly crenulate all around, triple-nerved ; lateral primary veins from 

 above the base of the leaf curving up and following quite near the bor- 

 ders to above the middle, where they anastomose with the lowest pair of 

 secondary veins, also opposite; all curving along the borders, campto- 

 drome. The leaf has the same areolation as those of P. aculeatus. Lam., 

 of Europe, from which it merely differs by its round base, the lower veins 

 closer to the borders, and the secondary veins from the middle only of 

 the leaf and nearly opposite. 



Habitat. — Near Florisant, South Park, Prof. Cope. 



Ehus(?) drymeja, sp. nov. 



Leaves narrowly lanceolate, acuminate, equally acutely serrate, penni- 

 nerve ; lateral veins close, numerous, simple, craspedodrome, parallel 

 from the base, on an acute angle of divergence ; areolation in primary 

 quadrate rectangular areas, divided into small irregular quadrate or 

 polygonal areolse. I doubt that this form, represented by numerous well- 

 preserved thickish leaves, may be referable to a species of Rhus. It is com- 

 parable to Quercus loncMtis, Ung., in Fl. of Sotzka, (p. 33, PI. ix, Fig. 1);
