82 UNITED STATES GEOLOGICAL SURVEY— TERTIAEY FLORA. 



branchlets found being very often divested of them, or with mere fragments, 

 as seen in fig. 22. The cones of this species are as yet unknown. 



Habitat. — Raton Mountains, New Mexico, where its remains are very 

 abundant {Dr. J. Le Conte). I found there mixed with them large pieces of 

 bark, covered with large oval-obtuse tubercles, placed in rows; they seem 

 referable to this species. Specimens in a good state of preservation were 

 sent also from Fort Ellis by T. Savage, with mostly undeterminable fragments 

 of dicotyledonous leaves. Frof. B. F. Meek obtained also, from chocolate clay 

 shale underlying a bed of coal near Fort Steele, fragments of stems bearing 

 scars similar in form and disposition to those of the branches of the Raton, 

 These specimens, however, were without any leaves, the only other discerni- 

 ble remains, figured in pi. Ix, fig. 37, being a fruit or scale of a cone, appar- 

 ently referable to Nordenskioldia borealis?, Heer.

Leaves distant, very narrow, needle-form, placed in right angle to and around the branches, or 

 curving backward and reflexed from near the point of attachment. 



None of the fragments representing this species are better than those 

 which we have figured. The leaves, eighteen millimeters long, less than one 

 millimeter broad, are exactly linear, filiform, grooved and nerved in the mid- 

 dle, abruptly pointed, and slightly enlarged at the point of attachment, distant, 

 and, as seen from the scars upon the branches and placed all around them, 

 either diverging in right angle or curved downward from near the base. 

 Both this and the former species are without relation to any species of fossil 

 Conifers known as yet from this country. But Count Saporta writes me that 

 he is surprised to find that two forms apparently specifically identical with this 

 and the former species are found in the Upper Cretaceous of France, that is, in 

 the Lignite formations of Saint Paulet, Gard. He says: — "I have a specimen 

 from Saint Paulet, which is like your figs. 17 and 18, and I have another, 

 obtained from Brongniart, which is undoubtedly identical with your figs. 19 to 

 24." He adds that the horizon of the first species, Abietites duhius, ought to be 

 the same as that of -4. setiger; that Sequoia hiformis is intermediate between 

 them, and seems to unite both these so different forms, as possibly representing 

 the same species. To this last supposition, I remark, that each of these three 

 species, es^ec\&\\y Sequoia hiformis and Abietites duhius, is represented by a large
