Description. Leaves of variable but small size, narrowly elliptical or 

 obovate to nearly orbicular in general -outline. Length ranging from 

 5.5 mm. to 2 cm. Maximum width, in the middle part of the leaf, ranging 

 from 4 mm. to 1.75 cm. Apex broad or narrow, bluntly pointed. Base 

 narrowly or broadly cuneate. Margins with relatively very large, some- 

 what irregular teeth, which are either serrate or dentate. Texture sub- 

 coriaceous. Petiole relatively long and stout, about one-half the length 

 of the lamina. Midrib curved or flexuous, thin. Secondaries thin, two or 

 three opposite to alternate pairs, diverging from the the midrib at acute 

 angles, indifferently camptodrome or craspedodrome. Tertiaries obsolete. 



This species, while it resembles Cissites crispus Velenovsky 1 and is 

 probably related to it, is entirely distinct. This is especially true of the 

 Magothy leaves contained in carbonate of iron nodules which the writer 

 has identified as this species from New Jersey and Delaware, both this 

 and the Earitan determinations are therefore referred to a new species 

 named in honor of the late Professor Newberry. 



It differs from Cissites crispus by its relatively longer and narrower 

 form ; its serrate and dentate instead of crenate teeth ; its more ascending 

 and frequently camptodrome secondaries ; its obsolete tertiaries ; and its 

 cuneate instead of markedly cordate base.
