FLORA OF THE KOOTANIE FORMATION. 311 



enough material to decide this positively. The seed is ovate-elliptical 

 in form, 5 mm. long, and 3 mm. wide in its broadest portion. It has 

 the smooth horny-looking epidermis characteristic of Cycadeospermum, 

 and is wrinkled from shrinkage. 



Order FINALES. 



Family TAXACE^. 



Genus CEPHALOTAXOPSIS Fontaine. 



Cephalotaxopsis ramosa Fontaine?'' 



PI. LXXIII, Fig. 8. 



A number of imprints of detached leaflets were found on several 

 pieces of the Geyser shale that closel}^ resemble leaflets of Cephalotax- 

 opsis ramosa Font., a plant found rathesr abundantly in the Lower Poto- 

 mac beds of Virginia. None of these were found attached and they 

 are all fragments of leaflets. Their texture is leather}^, but rather thin 

 for a Cephalotaxopsis, and they have a strong single nerve. They 

 appear to be certainly leaflets of some Cephalotaxopsis, but are not 

 well enough preserved and sufficiently abundant to disclose clearly 

 their specific character. They agree best with the narrower form of 

 leaflets of C. ramosa. 



Genus NAGEIOPSIS Fontaine. 



Nageiopsis longifolia Fontaine. 



PI. LXXIII, Fig. 9. 



Five or six fragments of shale from the Geyser strata show imprints 

 of pieces of strap-shaped leaflets with parallel nerves that have the 

 character of Nageiopsis longifolia Font., a conifer found first in the 

 Lower Potomac beds of Virginia. The imprints are all of fragments 

 of leaflets, the longest being from 5 cm. to 6 cm. in length, with a width 

 of 5 cm. or 6 cm. None of them are attached, but one specimen shows 

 the basal portion of a leaflet with the characteristic narrowing seen 

 in A^ longifolia, which gives the base of the leaflet an elliptical from. 

 This plant does not seem to be common in the Geyser strata.
