from the cuneate base or a slight distance above, running from 

 thence to the tips of the lobes. From 1.5 cm. to 4 cm. above 

 their origin the lateral primaries send off stout, lateral, more or 

 less subordinate branches which run to the tips of the subordinate 

 lobes. These latter may nearly equal the principal lobes as they 

 do in the complete specimen figured by Newberry in 1898, or 

 they may be more or less reduced as they are in the large speci- 

 men figured by the same author from Woodbridge, in which the 

 one on the right side is apparently but slightly developed. These 

 lobes are also subordinate in the dainty little leaf of this species 

 figured in the present report from the Hylton Pits. The second- 

 aries are numerous and camptodrome as a rule, although a single 

 one in the last-mentioned specimen runs directly to a prominent 

 serrate point on the lower side of the subordinate lobe, a short 

 distance below its apex. 



Although fragmentary remains of this handsome species were 

 discovered during the work of the Hayden Survey in Kansas, 

 and were described by Lesciuereux in 1876, the subsequently- 

 collected, more complete material has never been adequately 

 described.
