38 TRANSACTIONS OF THE [Nov. 14 
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 with the 
genus Luphorbia. It closely resembles some of the bract-like 
leaves of species classed under the sub-genus Poinsettia and I 
have indicated the apparent relationship in the specific name. 
Locality : clay at Kreischerville. 
Fruits AND SEEDS oF UncertTAIN AFFINITIES. 
On Plate I, a number of fruits and seeds are figured which 
might be grouped under Carpolithes, or Carpites, 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. 
Pl, 1. £4, 6, 8,'T1, 12; 14, 15, 16, 16g, 
f. 4. Fruit spheroidal, composed of apparently six rounded, elongated 
carpels, each ,%; inch broad by ~; inch long. Entire fruit not unlike a 
large dried berry of Celastrus scandens, L. 
Locality : shore at Tottenville, in a concretion, 
f.6. Thin, flat or slightly warped, top-shaped in outline, about + inch 
long. General appearance not unlike the achenia of some ‘species of 
Cy peraceee. 
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, ;°; inch long by 1g inch wide. 
Locality : clay at Kreischerville. 
f.11. Oblong ovate, apiculate at one end, rounded at the other. 
Margin rounded throughout, ;% inch long by 14 inch broad, 
Locality : clay at Kreischerville ; Wm. T, Davis. 
f,16,16a. Entire specimen consists of loosely arranged spike for 
raceme, about 34 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. Fruit consists of a slightly raised center, surrounded by a 
narrow rim or margin. Outline almost circular, not quite 14 inch in 
diameter. Center appearing as if filled withsmall seeds. It agrees quite 
closely with Carpolithes Potentilloides, Heer, as figured in Flor. Foss. Arct.
