FOSSIL FLORA. 683 



the south side of Stinkingwater Valley, at a high bluff east of the mouth 

 of Crag Creek, Wyoming. 



Sequoia, cones of. 



PL LXXXI, fig. 8; PI. LXXXII, figs. 6, 7. 



The specimens figured are fairly representative of these organisms. 

 They are quite fragmentary, yet appear to be cones. They are found in 

 the same beds with Sequoia langsdorfii, but not in actual connection with 

 that species, and I have preferred to keep them distinct, at least for the 

 present. 



Habitat: Fossil Forest, beds Nos. 5 and 6; collected by Lester F. 

 Ward and F. H. Knowlton, August, 1887. 



TYPHACEtE. 



PhRAGMITES? LATISS1MA 11. sp. 

 PI. LXXXIII, fig. 5. 



Leaf very broad; stria? fine, close together. 



The fragment figured represents all that has been collected of this form. 

 It is, of course, quite insufficient for proper diagnosis, yet it seems to be 

 different from anything hitherto described from that region. It is certainly 

 quite unlike anything found in the Yellowstone National Park. 



It must have been a very large leaf, for the fragment is over 3 cm. 

 broad, and it was probably a thick leaf. The stria? are very fine, straight, 

 and close together. It differs in size and fineness of stria? from P. alaskana, 

 to which it seems to be most nearly related. 



I have given it a new name with great reluctance, for it is too frag- 

 mentary to found a new species on, but for the present it may remain as 

 above. 



Habitat: Northeast side of Crescent Hill, Yellowstone National Park; 

 collected by F. H. Knowlton and G. E. Culver, August, 1888. 



SPARGANIACEvE. 



Sparganium stygium Heer. 

 Sparganium stygium Heer. Cf. Ward : Types of the Laramie FL, p. IS, PI. Ill, figs. 6, 7. 

 These specimens do not agree in all particulars either with those figured
