LESQUEEEux.] ENUMERATION OF CRETACEOUS PLANTS. 335 



Sequoia Formosa, Lesqx., Cret. Flor,, p. 50, PI. I, figs. 9 and d^. 



Cone spindle-shaped, tapering upioard from above the base and more 

 rapidly narrmved to a short petiole / scales closely oppressed and imbri- 

 cated, rhomboidal, margined. 



Sequoia Eeichenbachi ?, Heer, Cret. Flor., p. 51, PI. I, figs. 10, 10^. 



Cone small, oblong, oval; receptacles oval, pjointed at both ends; foliaceous 

 scales crumpled, deeply embedded into the sto7ie; seeds small, oval-oblong. 



In comparing tbis cone to the figures given of the species by Professor 

 Heer in his Moletin flora, the reference-^ was made especially to fig. 3 of 

 PI. I. Professor Heer remarks rightly that there is no relation between 

 these cones of Moletin and the one of Nebraska, the former being much 

 larger and the scales therefoie longer, and that though representing ap- 

 parently a species of Sequoia, the specific name should be left undeter- 

 mined until better specimens have been discovered. 



Sequoia fastigiata ? Sternb., Heer, Mol. Flor. p. 11, PL I, figs. 10, 

 13.— PL HI, figs. 2 and 8. 



Branches erect, slender ; branchlets filiform, fastigiate, crowded ; leaves 

 loosely imbricated, short, decurrent at the base, broadly lanceolate, acumi- 

 nate, subfalcate, or more or less curved upward ; nerved. 



We know of this species only what is seen in the small branch figured 

 8 and 8°, for the cones of the same plate, fig. 2, though observed upon 

 specimens of the same locality, have not been found in connection with 

 the branches bearing leaves. The leaves appear of the same form and 

 characters as those represented by Heer in his Moletin Flora, loc. cit., and 

 as those from the Greenland Upper Cretaceous flora by the same 

 author, p. 102, PL XXVII, figs. 5 and 6, merely differing by the presence 

 of a middle nerve recognizable upon the specimens of Kansas, and which 

 is not seen upon -the leaves of Grreenland and Europe. This mode of 

 division of the branches is the same, and in comparing the cones of our 

 fig. 2 with those figured by Heer from both Greenland and Moletin 

 specimens, the likeness appears very great indeed. As the leaves of 

 this species are very variable in size and the middle nerve generally 

 perceivable with great difiiculty, I am not disposed to separate it from 

 the only diii'erence of the more distinct middle nerve of the leaves, and 

 I consider it as very probably the same as that of Moletin. Heer re- 

 marks a character also recognizable upon the fragment from Kansas, 

 viz, the difference of the size of the leaves upon diliereut parts of the 

 branches. 



Habitat. — Kansas, Clay Center, H. C. Towner. 



Sequoia condita, sp. nov., PL IV, figs. 5-7. 



Branches rigid, pinnately divided ; branchlets slender, filiform, open or 

 oblique; leaves either short, oblong pointed narrotced to the decur ring base, 

 appressed to the stem, or longer, subulate acuminate, open and slightly fal- 

 cate, nerveless ; cone small, oval-oblong, scales rhomboidal, acutely nutm- 

 onillate. 



After briefly describing this species for the Bulletin Xo. 5, second 

 series of the Geological Survey of the Territories, I received from Clay 

 Center a number of fragmentary specimens satisfactorily showing its 

 various characters. They prove that the fragment, PL IV, fig. 7, 

 which I had considered as representing a different species, and described 

 8:S doubtiully referable to Sequoia subulata, Heer, of the Greenland 

 Cretaceous flora, belongs to the same species as the iTagment, fig. 5.
