244 KANSAS CITY REVIEW OE SCIENCE. 



P. Elegans, and Salix proteczfolia. Then we have a new species in the order 

 Amentacecz, Myrica Sternbergii. Also Betula, and a new species of Aluites, a new 

 one of Qiiercus, and Platamis PrimcBva; of the order U^'iicce, three new species of 

 Ficus, represented by fine large specimens. 



The order Laurineoe. is well represented by the genera Laurophylhim, Sassa- 

 fras, etc., and the order UmbelUflora has magnificent specimens of Aralia, Sa- 

 porteana, A. quinquepartita, A. Tonneri, A. Tripartita, (or imperfecta) and A. Con- 

 creta. Also specimens of Hedra, and Cissites. C. tenninerice is new in science. 



The splendid genus Protophyllum (catalpa) of the order Columniferce, is repre- 

 sented by leaves of P. Sternbergii, P. Quadratum, P. Minus, etc. The order 

 Aceracece has a new variety of Greviopses Haydeni, and a new species G. hetulce- 

 folia. The order Frangulacece has a new species of Phamnus. We have, also, 

 beautiful specimens of Phtagmites, a leaf with parallel veins. In. addition we 

 have a variety of Tornacia saporteana, which is, perhaps, new." Then we have 

 a new species, Anona Cretacea. A new Thusites, two new species of Sapindies. 

 We have also large numbers of perfect leaves of Aspdiophyllum trilobum, some 

 are a foot in diameter, with thick perforated midribs. The Araliopsis, is especial- 

 ly well represented by fine leaves of Sassafras Mirabile and S. Mudgii. I have 

 not yet seen Prof. Lesquereux's list of species collected by my party. But I 

 think we have over fifty species, all of them from eighteen localities that are scat- 

 tered over the Dakota of Kansas from Ellsworth to Ottawa county. Some locali- 

 ties are loo miles apart, and each is noted for its own peculiar species. In Ells- 

 worth county the localities are only a few miles apart. 



On Spring Creek we find the Protophyllum, (Catalpa). The. Sassafras is \Qxy 

 abundant on Thompson Creek. Blufif Creek has beautiful specimens of Liquid- 

 ambra integrifolia. Three miles southwest of Fort Harker are found the splendid 

 leaves of Aspidiophyllum trilobum, with some fine Menospermites obtusiloba and 

 Aralia rowueri. Skunk Creek, south of Fort Harker, furnishes Aralia quinque- 

 partita, A. tripartita, A. saporteana, and Laurophyllum reticulatum. The Elkhorn 

 locality coxAams Liriodendron, Phragmites and Salix. At Churchill P. O., twenty 

 miles above Salina, on the Saline River, Sassafras Mudgii. Sixteen miles north- 

 west of Salina, on Saline River, we find Sassafras Mudgii and Menospermites ob- 

 tusiloba. 



Near Glasgow, we find Liriodendron, Todea, Platanus, Populites, Rhamnus, 

 etc. Near Minneapolis are found Aspidiophyllm, trilobu7n and Populites Elegans. 

 Muberry Creek, near Clay Centre, furnishes Platanus Heeri. My explorations 

 have confirmed the opinion of Professor Lesquereux, " that the forests of Creta- 

 ceous Dakota Group, grew on isolated islands in a wide expanse of waters."
