shaped outline. Midrib curved. Nerves fine and numerous, starting at 

 about right angles from the midrib, continuing almost parallel and soon 

 becoming campdodrome. 



The only apparent comparison which I have been able to 

 make between this curious leaf and any living one is M'ith the 

 genus Euphorbia. It closely resembles some of the bract-like 

 leaves of species classed under the sub-genus Poin^ettia and I 

 have indicated the apparent relationship in the specific name. 



Ijocality : clay at Kreischerville. 



Fruits and Seeds of Uncertain Affinities. 



On Plate I, a number of fruits and seeds are figured which 

 might be grouped under GarpoUthes, or Carpiies, the generally 

 recognized generic titles for such organisms ; but so long as 

 their relationships are entirely problematic it seems a wiser 

 course to leave them unnamed. 



PI. I. f. 4, 6, 8, 11, 12, 14, 15, 16, 16a. 



f. 4. Fruit spheroidal, composed of apparently six rounded, elongated 

 carpels, each ^^ inch broad by ^g inch long. Entire fruit not unlike a 

 large dried berry of Celai<trns scandens, L. 



Locality : shore at Tottenville, in a concretion. 



f. 6. Thin, flat or slightly warped, top-shapod in outline, about i inch 

 long. General appearance not unlike the achenia of some species of 

 CyperacesB. 



Locality : clay at Green Ridge ; Heinrich Reis. 



f. 8. Curved lenticular in outline, with rounded ends and a center 

 which rises gradually from the convex margin. Concave portion of the 

 margin and ends, winged, ^g inch long by ig inch wide. 



Locality : clay at Kreischerville. 



f. 11, Oblong ovate, apiculate at one end, rounded at the other. 

 Margin rounded throughout, /ginch long by I4 inch broad. 



Locality : clay at Kreischerville ; Wm. T. Davis. 



f, 16, 16a. Entire .specimen consists of loosely arranged spike 'or 

 raceme, about ^4 inch long, composed of minute fruits upon short thick 

 pedicles. Under the microscope each fruit is seen to consist of an 

 apiculate oval seed, partly enclosed between two glume-like appendages. 



Locality : clay at Kreischerville. 



f. 12. Fi-uit consists of a sliglitly raised center, surrounded by a 

 narrow rim or margin. Outline almost circular, not quite ^4 inch in 

 diameter. Center appearing as if filled with small seeds. It agrees quite 

 closely with CarpoUlhes PotentiUoides, Heer, as figured in Flor. Foss. Arct.
