KNOWI/TON] KOOTANIF, PLANTS FROM GREAT FALLS, MONTANA 12/ 



CONIFEROUS LEAVES? 



Plate XII, Figs. 5, 6 



The material from Skull Butte, eastern Fergus County, Montana, 

 contains a number of isolated but fairly well preserved leaves that 

 appear to have belonged to some conifer. They are about 13 or 14 

 mm. in length and slightly over 2 mm. in width, the basal portion 

 being truncate or slightly rounded and the apical end rather ob- 

 tusely acuminate. They are provided with a single quite prominent 

 median rib. I have not attempted to place them more definitely 

 than indicated above, as they are too uncertain. 



Locality. — Canon north side of Skull Butte. 6 miles southeast of 

 Stanford, Fergus County, Montana.
