DESCRIPTION OF SPECIES— LAURINE^. 219 



in that of Greenland. The origin of the genus is therefore generally con- 

 sidered in Europe as Tertiary, rather Miocene. Two leaves described in 

 the Cretaceous Flora, vol vi of the Reports of the Geological Surveys of 

 the Territories, p. 83, pi. xxx, figs. 2, 3, have been found by Prof B. F. Mudge 

 in concretions of the Cretaceous Dakota group; and though their idenlity with 

 C Scheuchzeri, Heer, of the Miocene, is doubtful, they seem truly referable to 

 this genus. Another Cretaceous species has been also described as CHeerii 

 in Trans. Am. Phil. Soc, vol. xiii, p. 431, pi. xxiii, fig. 12, from an incomplete 

 specimen. The evidence of the old origin of the genus is contirmed by the 

 presence of most of our species of Clnnamomujn in the lower strata of tlie 

 Eocene Lignitic, where the best specimens have been found, especially at 

 Golden, in the White Sandstone underlying the coal beds, in close proximity 

 to strata bearing Cretaceous animal remains.

Leaf lanceolate, acuminate upward, narrowed downward to the petiole, triple-nerved ; lateral 

 veins obscure, apparently aerodrome. 



The fragment as seen by our figure is too incomplete for positive identi- 

 fication. The lateral veins do not follow the borders as closely as it is gen- 

 erally the case in this species; it might be referable to C. Scheuchzeri, Heer, 

 but for the apparently narrowly cuneiform base. The nerves are too thin to 

 authorize a reference to the following species.

Leaves oval-acuminate, rounded and narrowed to the petiole, triple-nerved; nerves thick, the 

 lateral ones curving nearly parallel to the borders, but at a distance, slightly branching. 



The leaves, generally oval, like those of Q.polymorphum, Al. Br., to which 

 this species is related, are narrower and more gradually acuminate; the 

 nervation is of the same type, but none of our specimens has any trace of 

 the axillary glands remarked in the European species; the divisions of the
