Description: '' Leaves large, coriaceous, palmately three- or five- 

 lobed, narrowed in an inward curve to a prolonged base ; decurring 

 to the petiole ; lobes long, oblong-lanceolate, abruptly pointed, sharply 

 equally dentate from above the base, the teeth turned outside or 

 slightly upward, separated by shallow sinuses; primary nerves broad 

 and flat; secondaries more or less oblique, slightly curving or nearly 

 straight in passing to the borders, entering the teeth, craspedodrome, 

 mostly simple ; areolation distinctly reticulate, in irregularly quadrate 

 or polygonal meshes. The leaves, which are 15 cm. to 16 cm. long, 

 excluding the petiole, vary, of course, in width according to the num- 

 ber of lobes and their divergence from the median nerve, which in 

 most of the specimens that I have seen averages 35°. The lobes are 

 a little broader in the middle, slightly narrowing to the sinuses, 7 cm, 

 to 10 cm. long, and from 2 cm. to 3 cm. broad at the middle." — Les- 

 quereux, op. cit. The anastomosis is so marked that near the edge 

 of the lobe the secondary veins might be thought to be camptodrome. 



Occurrence: Ellsworth County, Kansas, Dakota Sandstone (Cre- 

 taceous). Baron de Bayet Collection, Accession No. 2348, Carnegie
