As will be noted on examining the above list, nearly all the species 

 are found in the Permian of Europe or America. The species printed 

 in boldfaced type are characteristic of the Permian. The beds are 

 clearly of lower Permian age. 



The red and green sandstones three-fourths mile east, and the beds 

 of similar character about 4 miles southeast of Electra, Texas, con- 

 tain great numbers of Glgantopteris mingled with Tseniopteris. In 

 this part, regarded by Gordon * as near the top of the Wichita forma- 

 tion, surviving "Coal Measures" ferns have not 3^et been found. 



Several small fragments of Giganto pteris which were many years 

 ago transmitted to the United States National Museum - from Fort 

 Concho, near San Angelo, Tom Green County, Texas, were examined 

 by Leo Lesquereux, who wrote on the label "Pecuhar fern quite 

 unknown to me." The fragments probably represent a new species 

 of the genus. 



The OMalwma -flora. — The Wreford limestone, which by the Kansas 

 University Geological Surve}' is made the base of the Permian,^ is 

 said to be replaced to the southward by arenaceous beds to which 

 tlie name Payne has been applied by Kirk.^ Above this sandstone 

 the Permian of Oklahoma is largel}' composed of red sandstones and 

 shales. Fossil plants were collected from tliis series at two localities 

 in the State: 1. About 2 miles north of Perry, in chocolate-red and 

 greenish grits regarded by Gould as probably near the horizon of the 

 Winfield formation of Kansas; 2. The ^IcCann quarries in the red 

 sandstone about 2 miles east of Eddy, in Kay County. The latter 

 point, wliich is well up in the Enid formation,^ is also known as the 

 source of some of the fossil vertebrates described by Prof. S. W. 

 Williston.
