These leaves have a distant resemblance to Lesquereux's 

 Cisst'tes /ormosus Heer (Fl. Dak. Group, ^/. 21. f. ^) but 

 bear no resemblance to the Amboy Clay leaves which New- 

 berry refers to that species. Our leaves also suggest some 

 forms of Aralia such as A. quinqiiefartita Lesq., but the 

 base is apparently not decurrent and the primaries branch 

 from the midrib at the same place, the lateral ones at nearly 

 right angles. 



Aralia Brittoniana sp. nov. PL ^5. f. j. 



I have been unable to identify this with an}^ known species 

 of Aralia and therefore add another to the long list of diver- 

 sified leaves of this genus which have been found in the 

 Raritan and Matawan formation. In size and outline it re- 

 sembles Aralia acerifolia Lesq. of the Fort Union beds of the 

 West, but the secondaries are stronger and more regular. 

 The specimen denotes a leaf which was trilobed with an evi- 

 dent tendency to produce an extra latero-basal lobe on each 

 side ; with a broadly truncated base which curves upward 

 for about half the distance to the tip to form a point above 

 which the margin is concave ; lobes presumably acute ; ter- 

 minal lobe broad with moderately convex sides ; sinus to be- 

 low the middle, rounded ; primary and secondary venation 

 strong, but tertiary venation entirely obsolete ; lateral pri- 

 mary could not have branched far from the base and forms 

 an angle of about 45° with the midrib, leaving room for a 

 secondary below ; secondaries regular, leaving the primaries 

 at a wide angle and running straight to within a short dis- 

 tance of the margin and then curving to join the secondary 

 next above. Our only specimen was evidently not bilaterally 

 symmetrical. 



ERICACEAE. 



Andromeda Linn. Sp. PI. 393. 1753- 

 At the present time a monotypic genus of the north tem- 

 perate and subarctic zone. Many fossil leaves have been 

 referred here, some twenty-five species in this country alone.
