width, which is from tip to tip of the lateral lobes. Trilobate. Apical 

 lobe very short and conical. Lateral lobes short and pointed, somewhat 

 recurved outward. Sinuses open, shallow and rounded, not extending 

 more than one-fifth of the distance from the apex to the base. Lateral 

 margins at first full and rounded, then curving inward to the decurrent 

 base. Primaries three in number, equally stout and curved, the laterals 

 subopposite and suprabasilar. Secondaries numerous, curved, campto- 

 drome, branching from the primaries at angles of less than 45. Ter- 

 tiaries transverse. Margins entire throughout. Texture coriaceous. 



This characteristic leaf is probably the end term of a series of forms 

 starting with Araliopsoides cretacea, but whether it represents an extreme 

 of variation of that species or a distinct but related species cannot be 

 definitely determined. The present form suggests various species from 

 the Dakota sandstone of the West, which Professor Lesquereux referred to 

 the genus Cissites. It is also similar to the form from the Cenomanian of 

 Bohemia described by Velenovsky 1 as Aralia anisoloba, differing slightly 

 in outline and lacking the remotely dentate margins of the latter.

2 This form was cited in 1878 by Saporta and Marion (M6m. Cour. Sav. 

 Etrang. Acad., tome xli, 1878, p. 78), as Araliopsis (Sassafras) cretacea, but 

 there is no evidence to show that they had any generic proposal in mind.
