10(j THE FLORA OF THE DAKOTA GROUP. 



mons now in the collection of the U. S. National iMnseuni. The ohavacter 

 iiKtst important to separate this species from some forms of C. polymoriihum 

 (Al. Hr.) Heer and C. Sfltenchzeri Ileer, is the position of the primary lateral 

 nerves, which are quite near the base of the leaf. I have already described 

 two leaves of this kind in Cret. Y\., PI. xxx, Figs. 2 and 3, the first being 

 comparable to Fig. 8 of Saporta and Marion (loc. cit.), being still narrower, 

 with primary lateral nerves at a greater distance from the base of the leaf, 

 not less than 8™°" (3°"" in the leaf of the French authors), and still naiTower, 

 the widest part in this last leaf being 18°"" while it is 25°"" in the leaf figured 

 in the Flora of Gelinden. The character of the two leaves figured here 

 agrees well with those of the leaves (Figs. 7 and 9) of Saporta and Marion as 

 well as that of the fragmentary leaf of the Cret. Fl., PI. xxx. Fig. 3. Even 

 in this one the primary lateral nerves are really basilar, and thus it is 

 evident that, adnntting the characters as specific, three of our leaves repre- 

 sent ('. f'lHiisoidi'inn Sap. & Mar. 



Admitting the identity of the leaves from Kansas with those from 

 France, or considering them all of the same species, the dirt'erence mentioned 

 above has to be put aside, and thus my remark on the leaves of Cinnamo- 

 nuuu referable to C. Scheuchzeri Heer remains valid at least for Fig. 2 of 

 the Cret. Fl. Heer has recognized, in the Upper Cretaceous of Patoot, and 

 described' C. pJlrpsoldeMm in a fi-agmentary leaf which he refers to the species 

 from the basilar po.sition of the lateral i)rimaries. It has the same character 

 as that of Fig. 8 of our plate.

PI. LI, Figs. 6, 7. 



Leaves uaiTOwly elliptical, shaxidy acute, rounded at base in narrowing 

 to th(^ petiole, entire, subcoriaceous; midrili narrow, lateral primaries two 

 ])airs, one from the base, ascending in following the borders to below the 

 middle of the leaf, the other supra-basilar, joining the midrib about l"" 

 above the lower, but parallel, curving at a distance from tlie borders, tending 

 to the apex but effaced and disappearing at a short distaiu-e below. 



By their texture, form, and nervation these t^\'o leaves are very much 

 alike, are of simple nervation, aud appeal- referable to Cinnamomum. Their 

 texture, if not very .thick, is solid and their surface smooth. I am, how-
