part also sharply and acutely nerved; the nervation obscured by a rough 

 epidermis, in such a way that the primary veins are scarcely discernible 

 even with the glass, and the intermediate ones totally obsolete. From the 

 former species, it greatly differs by the abruptly narrowed, shorter, though 

 acuminate point of the rachis, which is convex on the under surface, rough 

 in the middle, smooth only on the borders, where it is marked by parallel obtuse 

 striae, three millimeters distant; by the less numerous rays more distinctly 

 and sharply carinate; and by the obsolete nervation. It is from this character 

 especially that I referred to this species, in Supplement to Annual Report, 

 1871, a large number of specimens from Fischer Peak, of the Raton Mount- 

 ains, where they were collected by Dr. Hayden's expeditions, and later by my- 

 self It is there very abundant, for, except one, all these specimens of Palms 

 of Dr. Hayden, forty-seven in number, represent it in fragments of leaves, 

 of petioles, of stalks, of racemes, and fruits. My own specimens are of the 

 same kind. As mentioned in Annual Report, 1872, p. 375, I found it at the 

 Gehrung's coal, near Colorado City, then abundantly at Golden, with fruits of 

 Palms (Annual Report, 1872, pp. 383, 391), and at Black Buttes, in the Sau- 

 rian bed, where I obtained even fragments of leaves glued to fragments of 

 bones of Agathamnas sijlvestris (Annual Report, 1872, p. 398). In all these 

 specimens, the character of the nervation is the same: numerous primary 

 veins, ten to twenty in each half-ray, indistinctly perceivable under the 

 rough epidermis, and no trace of intermediate veinlets. As seen in the 

 description of the fruits which I refer to this species, they have been obtained 

 in most of the localities where fragments of leaves were found. I have also, 

 referable to it, the base of a petiole ten centimeters broad, merely convex, 

 and rays four and a half centimeters wide, the largest which I have seen of 

 this species. 



Habitat. — Fischer Peak, Raton Mountains, New Mexico (Dr. F. V. 

 Hayden); Gehrung's coal, Colorado, Golden, Black Butte, etc. Dr. Newberry 

 has it from the Fort Union Lignitic, Bellingham Bay, etc.
