Description

From Hollick (1930) (p. 82)

"Leaf linear-lanceolate-elliptical, entire, about 6.25 centimeters in length by 1.75 centimeters in width across the middle; nervation consisting of a midrib two acrodrome lateral primary nerves, and a series of uniformly fine secondary nerves that diverge from the midrib at obtuse angles and connect with the lateral primaries above and are camptodrome between the lateral primaries and the margin, where they coalesce and form a delicate, undulate marginal nerve."

 

Remarks

From Hollick (1930) (p. 82)

"This specimen belongs to the general type of leaves that have been referred and transferred, from time to time, to the genera Daphnogene, Cinnamomum, Cocculus, Paliurus, and Zizyphus and it closely resembles Cocculus cinnamomeus Velenovsky (1885) (p.4 (65), pl. 8 (31), figs. 16-21) from the Cenomanian of Bohemia, but it is somewhat more slender and elongated, and its surficial characters appear to indicate relationship with the Lauraceae."
