CENOZOIC TIME. 



Bornstadt Eocene ; and Black Butte, Myrica Torreyi, closely like one of Mount Promina, 

 Flabellaria latania Hooker, and F. Eocenica A. Brngt. The same beds that afforded 

 the Dinosaurian remains, described by Cope, contain the plants Sabal Campbelli Newb. 

 and Platanus Raynoldsii Newb., which are found at three or four other localities of the 

 same coal series, along with Ficus corylifolius Lsqx., Laurus obovata Weber, and 

 Viburnum dichotomum Lsqx., not yet observed elsewhere (Lesquereux). The Missis- 

 sippi beds contain the following Rocky Mountain species, Flabellaria Zinlceni Heer, 

 Populus Arctica Heer (an Arctic species), Quercus chlorophylla Ung., Laurus pedata 

 Lsqx., Cinnamomum affine Lsqx., C. Mississippiense Lsqx., Magnolia Hilyardiana 

 Lsqx., M. Lesleyana Lsqx., and Juglans appressa Lsqx. (Lesquereux) The Rocky 

 Mountain region has afforded the following Arctic species, Sequoia LangsdorfiiBr., 

 Phragmites (En'mgensis A. Brngt. (Miocene, in Europe), Populus decipiens Lsqx., P. 

 lancifolia Heer (Miocene, in Europe), P. Zaddachi Heer, Salix Grcenlandica Heer, 

 Alnus Kefersteinii Gopp. (Miocene, in Europe), Quercus Lyellii Heer (Miocene, in 

 Europe), Q.phtania Heer, Q. drymeja Ung. (Miocene, in Europe), Q. Wyomingiana 

 Lsqx., Q. Olafsenl Heer, Q. Laharpi Gopp., Corylus Mc Quarry i Heer, Fagus Deu- 

 calionis Ung. (Miocene, in Europe), Ficus tiliaifolia A. Brngt. (Miocene, in Europe), 

 Platanus Gulielmai Gopp. (Miocene, in Europe), Platanus aceroides Gopp. (Miocene, in 

 Europe), Cinnamomum Scheuchzeri Heer (Miocene, in Europe), Andromeda reticulata 

 Heer, A. vaccinifolia Ung., Viburnum Whymperi Heer, Vitis Olriki Heer, V. Islandica 

 Heer, Magnolia Inglefieldi Heer, McClintochia Lyellii Heer, Paliurus Colombi Heer, 

 Zizyphus liyperboreus Heer, Rhus bella Heer, Juglans acuminata (?) Heer (Miocene, in 

 Europe). Lesquereux, from whom this catalogue is taken, thus shows a close relation 

 between the floras of the Arctic and of more temperate Utitudes, as well as a relation 

 to the European Miocene flora. The latter fact seems to imply that the migration was 

 from America to Europe, as the European species existed in Europe only after their first 

 appearance in America. Lesquereux refers three of the above species exclusively to what 

 he regards as a later division of the Eocene than the others: all the others are found in 

 his Lower division. To the later, he refers the Rocky Mountain localities at Washakie 

 Station, Carbon Station, Evanston, Sage Creek, etc., in Utah: and to the older, the 

 localities of the Raton Mountains, Golden, Denver, etc., in Colorado; Black Butte, Wy- 

 oming; Fort Ellis and Elk Creek, Montana; Fort Union, in New Mexico; and in 

 Mississippi.

 group of Safford; Fig. 884, Cinnamomum Mississippiense 

 Lsqx., from Mississippi, northern Lignitic group, at Win- 

 ston; Fig. 885, Calamopsis Danai Lsqx. ,from Mississippi,

 Lagrange group of Tennessee; Fig. 887, Carpoliihes ir- 

 regularis Lsqx., from the Brandon Lignite bed; Fig. 888, 

 Carpolithes Brandonensis Lsqx., the most abundant of the 

 Brandon nuts, natural size. The kind of plant producing 

 these two fruits is undetermined. Among the other Bran- 

 don fruits, Lesquereux has recognized the genera Carya, 

 Fagus, Arhtolochia, Snpindus, Cinnamomum, lllicium, 

 Carpinus, and Nyssa. (Amer. Jour. Sci., IT. xxxii. 355.) 

 The plants of the Lignite bed of Lauderdale (which is 

 distinctly overlaid by the Claiborne Eocene) " show the 

 greatest affinity with species of our time, and are appar- 

 ently of as recent an epoch as the fruits of Brandon." 

 (Lesquereux.) 



In the beds of the Middle or Upper Eocene, in the 

 Green River or Fort Bridger basin, overlying unconformably the Lignitic Series (re- 

 ferred by Lesquereux to the Miocene, but by Marsh and Cope to the Eocene), there 

 nave been found, according to Lesquereux, species of Sabal (palm), Taxodium, Salix, 

 Myrica, Quercus, Ficus, Platanus, Laurus, Eucalyptus, Ilex, Ceanothus, Juglans, Carya,
