LANCE FLORA OF EASTERN WYOMING 131 



U. S. National Museum (specimens No. 5, Locality 8536). Comparable scales, referred to Dani- 

 mara acicularis Knowlton,' from the Judith River formation differ from the Lance and Laramie 

 species chiefiy in their consistently shorter apical spines; they undoubtedlj^ belong to the same 

 genus. 



I can see no justification for the retention of the generic name Sequoia for this species. 

 Neither the foliage nor the cone scales resemble in any way the living species of Sequoia. An 

 examination of herbarium specimens of all available species of conifers at the New York Botanical 

 Garden has convinced me that the closest resemblance is to the living AraucariaceEe. The 

 foliage is of the same type seen in Araucaria excelsa (Lamb.) R. Br. and A. cunninghamii Ait. 

 The needles of these species are radially arranged, are marked by a medial fold or false midrib, and 

 are attached to the branches in the same manner as in the fossil specimens. They differ only in 

 their shorter length and greater width. It is significant, moreover, that the cones of these living 

 species are deciduous, as in the fossil species, and have cone scales which closely resemble those of 

 the fossil specimens in size, shape, and terminal spines. 



Occurrence — Localities P3853, P3859. 



Collection—V. C. Mus. Pal., Plesiotypes Nos. 2474, 2475, 2476, 2477, 2478, 2479, 2480, 2481, 

 2482. 



Family TYPHACE.^ 



Genus TYPHA Linne 

 Typha sp. 



There are 9 specimens of this ubiquitous form. None of these has characters sufEciently 

 well defined to attempt specific determination or description. 



Remains of this type, generally referred to Typha, are common throughout Cretaceous and 

 Tertiary time. Of no use for correlation purposes because of their lack of diagnostic features, 

 they indicate a wet habitat, with inadequate drainage resulting in shallow standing bodies of water. 



Ocrarrence— Localities P3651, P3853, P3856, P3857, P38o8, P3859.

Family CYPERACE^ 



Genus CYPERACITES Schimper 



Cyperacites sp. 



Remains of finely parallel-veined leaves, referable to the form genus Cyperacites, are fairly 

 abundant in the collection from Locality P3857. These are the same as other specimens from 

 the Lance Creek area which are in the collections at the U. S. National Museum.- These mono- 

 cotyledonous leaves do not have any characters by which they can be defined or recognized as 

 "species"; they are recorded here only for their ecological connotations. 



Occurrence — Locality P3857.
