This exceedingly variable species is well represented by the extreme forms here 

 figured, which, however, do not differ from each other any more than do those fig- 

 ured by Lesquereux (loc. cit.) and are not nearly so diverse as those depicted by 

 Newberry from the Cretaceous of New Jersey (loc. cit.).

Sassafras angustilobum n. sp. 



PL XXIX, figs. 1-3. 



Leaves palmately 3-lobed, entire, more or less decurrent below; lobes blunt pointed, narrow, linear wedge- 

 shaped or slightly inflated about the middle; lateral primaries divergent, normally symmetrically supra- 

 basilar, but occasionally with one lower than its opposite. 



These leaves, except for their blunt lobes, might readily be taken for small 

 specimens of the narrow forms of Sassafras cretaceum Newb., a or S. acutilobum 

 Lesq. & They are also suggestive of certain species of Sterculia, especially 8. Krejcii 

 Vel., c and 8. aperta Lesq., d although in both of these species the lateral primaries are 

 apparently strictly basilar.

Sassafras cretaceum Newberry? 

 PI. XXX, fig. 10. 



Sassafras cretaceum Newb., Annals New York Lye. Nat. Hist., vol. 9, 1868, p. 14; Mon. U. S. Geol. Survey, 

 vol. 35 (Later Ext. Fl. N. Am.), 1898, p. 98, pi. 6, figs. 1-4; pi. 7, figs. 1-3; pi. 8, figs. 1, 2. 



This imperfect specimen apparently represents a lower part of some one of the 

 broader leaf forms described and figured by Newberry under the above name, but 

 any attempt to identify it with any particular form is ineffectual on account of its 

 fragmentary condition.
