Daphnophyllum dakotense Lesquereux, The Flora of the Dakota Group, U. 

 S. Geological Survey, Monograph XVII, 1892, p. 99, PI. 51, figs. 1-4, and 

 PI. 52, fig. I. 



Description: The description, which Lesquereux, op. cit., gives of 

 his leaves, fits our specimen very well, with the exception that the sec- 

 ondaries are opposite. The lowermost secondaries of our leaf do 

 not show very distinctly, but they do not appear to be opposite. PI. 

 52, fig. I, Lesquereux, op. cit., sho\vs the secondaries alternate with 

 the exception of the lowermost pair. I found with the specimen twa 

 loose labels in different handwriting; the one contained the name D.. 

 angustifolinm, the other one D. dakotense. I think our specimen, 

 which is a split-open nodule, showing both upper and lower surfaces, 

 agrees more closely with the latter, which name I have given to it.
