tliL' leaves (if wliicli are <i-eiierallv iimcli larger. Heer considers his species 

 as the equivalent of Miirtophyllum (Eucalyptus) Geinitzi of the Kreidefl. v. 

 Moletein, p. 22, PI. xi, Figs. 3, 4, represented by two leaves not any larg-er, 

 2.5"°' long, and tapering to an acumen, with the base not decurrent, but 

 naiTowed to a short, naked petiole. These material differences prevent the 

 identification of the Kansas leaves with those of Moletein and Greenland, 

 though the relation is very close. 



E. (lakotensis is also comparable to E. angasta Velenovsk}', ' but differs 

 b\- the base of the leaves decurring and ajijiarently obtuse.

 XLYi, Figs. 12c, d, 13. 



Leaves coriaceous, lanceolate or linear-lanceolate ; narrowed to the 

 apex and to the base; median nerve stout; secondaries at an acute angle of 

 divergence, confluent with the marginal nerve. 



There is only a fragment of a leaf, which, however, distinctlv repre- 

 sents Heer's species, especially as figured on PI. xix. Fig. Ic, for the size 

 of the leaves, the direction of the secondaries and their confluence with a 

 marginal nerve, and im PI. XLVi, Fig. 12c, for the areolation in larg'e 

 me-shes formed by undulate nervilles cut at right angles by thin, interme- 

 diate tertiaries.

Kreidefl. v. Niederschoena, p, 27, PI. i.ii, Fig. 13. 



Leaves small, coriaceous, entire, linear-lanceolate, acute at base, nar- 

 rowed to the apex: ])rimary nerve strong; secondaries Aery thin and close, 

 at an acute angle of div(n-gence. 



The above is the description as given by Heer. The leaf from Kansas 

 has exactly the same form as that from Niederschoena, being somewhat
