Description: The following is Heer's description, written in 1882: 

 " Nuce ovali, 34 mm. longa, 17 mm. lata; foliis magnis, foliolis oval- 

 ibus, basi inaequilateralibus, integerrimis. nervo medio valido, nervis 

 secundariis angulo semirecto egredientibus, curvatis." 



Our specimen is not quite complete at the apex and base. It is 

 about 9 cm. long and 3.3 cm. wide a little below the middle. It is 

 oblong, tapering to the apex, and narrowed toward the petiole, entire, 

 slightly unequal. The midrib is strong below, becoming rather faint 

 toward the apex. There are about twelve pairs of secondaries emerg- 

 ing at an angle of about 60 degrees, curved toward the margin, 

 camptodrome. The areolation is not distinct. It is rather difficult, 

 from the indistinct nervilles, to determine the species, but I think 

 there is no doubt about the genus, judging from the general character 

 of the leaf and the secondaries. Berry says in Bulletin Torrey Bo- 

 tanical Club, op. cit., " A rather curious point of identity is the fact 

 that the Greenland, New Jersey, and Kansas leaves are all inequi- 

 lateral." 



Occurrence: The leaf has quite a wide distribution. It has been 

 reported from the Dakota Sandstone, ten miles northeast of Delphos, 

 Kansas. Our specimen comes from Ellsworth County, Kansas, Da- 

 kota Sandstone (Cretaceous). Baron de Bayet Collection, Accession

Genus Betulites. 



The collection contains thirty specimens, which I have referred to 

 three species of Betulites; four to Betulites popnlifolius Lesq.. two to 

 Betulites rugosus Lesq., and the remainder to nine different varieties 

 of Betulites Westii. The leaves are, for the most part, very well
