DESCRIPTION OF SPECIES. 139 



twisted or iin-liiu'd to one side, witlmut trace of nervation, only sliglitlv 

 broader at the middle. I Ijelieve, therefore, that both these leaves repre- 

 sent the same species, thonyh their true generic relation remains uncertain. 

 The thickness, the form, and the size of these leaves seem to refer them to 

 the Myrtaceu'. As no ti-ace of the secondary nerves are marked upon the 

 figure of the leaf by Ettingshausen (loc. cit.), it is j)robable that the nerva- 

 tion is described bv the author of ('. iiir/itlciira'forn/r Ett. of Hiiring, which 

 he compares to his species. 



Habitat: Ellsworth County, Kansas. No. liVI of the nniseum of tlie

A larger leaf than that figured under this name in the Cret. and 

 Tert. Fl., PI. iv, Fig. '>. The form of the leaf and characters of nervation 

 are the same. Hut it is doubtful if these two leaves, though the base is 

 rounded and connivent under the inidi-il), can l)e referred to the Haraame- 

 lidese. Species of Quercus, .such as (J. lnfissitiKi, Hosius Paleontogr. vol, 17, 

 PI. XIII, Fig. 11, and Q, irrsffalira Hosius, & v. d. Marck, Westtal. Ki'eidefiora,
