144 DESCRIPTION OF SPECIES. 



PALM^E. 



FLABELLARIA, Schp. 



Flabellaria Florissanti, ep. nov. 

 Plate XXIV, Figs. l-2a. 



Fronds large; rays diverging all around from the top of the nearly flat not keeled 

 long rachis; rays large, very numerous, acutely keeled ; primary nerves distinct; close 

 intermediate veinlets, 3, 4. 



This species has some degree of likeness to Flabellaria eocenica, Lesqx., 

 "U. S. Geol. Rep.," vii, p. 3, pi. xiii, figs. 1-3. The rachis is not carinate 

 but merely indistinctly lineate lengthwise, and the top of the rachis on one 

 side of the leaf is also nearly truncate. The nerves are less distant and 

 the intermediate veins less numerous. It is still more intimately related 

 to Flabellaria. Lamanonis, Brgt., and perhaps identical with it as figured 

 in Sap., "Et.," i, p. 7<». pi. iv, fig. 5, — at least the number of primary nerves 

 in each division of the rays and that of the intermediate veins are about 

 the same. The lateral rays are more sharply keeled in the American form 

 and also more open, the lateral ones being at right angles to the more 

 distinctly truncate top of the petiole.

PALMOCARPON. 

 Palmocarpon? globosum, sp. nov. 

 Plate XXIV, Pig. 3. 

 Fruit large, globose, striate lengthwise. 



The fruit is exactly globose, 18 millimeters in diameter; the testa 

 appears to have been woody, though the fruit is flattened. This fruit has 

 not been found in connection with the palm-leaf described above, but at a 

 different locality, and therefore its reference to Palms is not positive. It 

 resembles Carpites lineatus, Newby., as figured, pi. lx, fig. 1, "U. S. Geol. 

 Rep.," vii, a species abundantly found at Evanston, where no remains of 

 Palms have been discovered. 



Hab.— Florissant. U. S. Geol. Expl. Dr. F. V. Hayden.
