AN ENUMERATION WITH DESCRIPTIONS OF SOME TERTIARY 

 FOSSIL PLANTS, FROM SPECIMENS PROCURED IN THE EX- 

 PLORATIONS OF DR. F. V. HAYDEN, IN 1870. 



By Leo Lesquereux. 



This eniimeratiou may be considered as an appendix to the paper on 

 :.he same subject^ in the last report of JJr. F. V. Hayden. This report 

 >vas just delivered and already in the hands of the printer when the 

 naterials on which the present notes are written were received. The 

 ?I)ecimens would have been reserved for a later examination, with that 

 )f others which may be procured this year. But as some of them give 

 evidence of the age of formations at some localities which in the report 

 ire marked as unknown ; as others represent new and remarkable forms ; 

 md others still have better preserved remains of species indifferently 

 iuown as yet, it was advisable to examine them at once and to prepare 

 lud publish a short account of them. 



In this paper the same plan is followed as in Dr. Haydeu's report : 

 Lst, description of species, grouped according to the localities where they 

 lave been found 5 2d, some remarks on the analogy of these species, in 

 •elation to their geographical and stratigraphical distribution and to 

 "jheir typical characters, &c, 



1. GrREEN E.IVEE,, ABOYE FISH-BEDS. 



Fine-grained, buif-colored, hard shale, breaking more or less irregu- 

 larly in horizontal layers. 



Hemitelites Torelli, Heer (?). Eepreseuted by a very small frag- 

 aient, only a single oblong leaflet, entire or slightly undulate on the 

 Dorders, with nervation of this species as figured in Fl. Arc, 2, PL xl, 

 Fig. 1-5. Identity cannot be positively ascertained from such a speci- 

 men. 



Arundo Goppeeti, Munst. To this species I refer an irregularly, nar- 

 rowly, striate stem with round knots, as in FI. Ter. Helv.,Pl. xxiii, Fig. 11, 

 The same specimen bears a crushed fascicle of seeds of an Arundoi^}). 

 Other specimens still doubtfully referred to this species represent roots or 

 root-stocks, varying from J of an inch to 1^ inches in diameter, irregularly, 

 more or less striate- wrinkled in the length, marked also, as in the first 

 specimens, by round knots, placed at a distance from each other and 

 without trace of articulations. These remains may belong as well to a 

 Phragmites as to an Arundo: The com|)arison of the seeds may indicate 

 their true relation. 



Phragmites Oening-ensis, A1. Br. Fragments of doubly striated 

 stems, marked by articulations as in Report, p. 284.* 



JuNCUS, species. Fragments of stems of various size, like Jmieus 

 retraetus, Heer, or Juncus ScJieuzeri, Heer, in Fl. Ter. Helv., PL xxx, 

 Figs. 2 e and 3 c. 



" Quotations marked Eeport refer to my former paper in Dr. F. V. Hayden's last 

 report, 1872. •
