422 GEOLOGICAL SUEVEY OF THE TEKEITORIES. 



alternate, the lower ones forking above the middle, the upper ones 

 simi^le. 



Though this form is very much like that published by Heer, {loc. 

 cit.,) from the Cretaceous of Moletin, it differs in some points. 1. The 

 pinnules are connate to one-fourth of their length ; they are larger, 

 more obtuse, and the second ar^^ veins are forked. In the specimens 

 from Moletin, the pinnules are separated to the base and have no trace 

 of secondary veins. A small specimen published by the same author 

 from Quedliuburg, PI. i. Fig. 3, shows, however, the pinnules connate, 

 as in the American form, with secondary veins figured simple. The frag- 

 ment indicates a smaller form ; not sei^arable, however, from mere differ- 

 ence of size. I consider it, therefore, as representing the same species. 

 As Heer has figured a specimen with fructifications, a fructified speci- 

 men of our plant may decide the question of identity. — Fort Harker. 



Sequoia Eeichenbachi, Heer, Mol. Fl., p. 8, PI. i, Fig. 2-3. 



The specimen represents a cone cut vertically, and thus exposing a 

 narrow axis on which are attached horizontally, linear or narrowly ovate 

 receptacles, attenuated at both ends, containing a small oblong seed 

 separated by foliaceous scales. The form of the cone is the same as that 

 of both those which are represented by Heer's figures, (loc. cit.) It is 

 only slightly longer and narrower, and the receptacles of the seeds more 

 closely approached to each other. The specimen does not bear any 

 remains of leaves of Conifer, but small round, smooth branches, appar- 

 ently referable to the same species. — Fort Harker. 



Caulikites spinosa, s}). nov. 



Stem or branch cylindrical, IJ cent, in diameter ; its surface marked 

 by small irregular points or depressions, resembling scars of scales ; it 

 bears apparentlj^ strong spines ; one of them is marked, going out of 

 the stem at right angles. Its scars are left in round holes through the 

 stone. The spines and the stem, too, enlarge to the point of attach- 

 ment. — Fort Harker.

I found at Salina three leaves of this species. They vary in size, and 

 also in the more or less pointed form of the lobes, and in their direction, 

 one specimen showing the lower divisions turned downward rather than 

 horizontal. 



POPULITES FAaiFOLIA, Sp. noV. 



Leaf elliptical, entire, subcoriaceous, tapering from the middle to a 

 slightly obtuse point, narrowed to a thick petiole; pinnately veined ; 

 secondary veins numerous, parallel, craspedodrome. 



The thick petiole is broken near the base of the leaf, which tapers to 

 it. The general form is that of Populus onutabilis, the leaf being en- 

 larged in the middle, and tapering upward and downward about in the 

 same degree. It is 10 cent, long, 8 cent, broad, with eight pairs of 

 secondary veins, the lower ones dividing outside, all the veins and 

 divisions entering the borders. The leaf is thickish but not quite 

 coriaceous. — Fort Harker.
