126 SMITHSONIAN MISCELLANEOUS COLLECTIONS [vol. 50 



ORDER CONIFERS. 



SEQUOIA GRACILIS Heer 



Sequoia gracilis Heer, Fl. Foss. Arct., vol. 3, 1873, Abth. 11, p. So, pi. xvm, 

 fig. 1 ; pi. xxii, figs. 1-10. 



This species, described originally from the Kome (Urgonian) beds 

 of Greenland, was first detected in the Kootanie at Great Falls by 

 Newberry. The present collections contain it from these localities, 

 some of the specimens being especially well preserved and agreeing 

 perfectly with the figures from the Greenland beds. 



Locality. — Flood siding 5 miles southwest of Great Falls; north 

 side of cut on high-line railroad west of smelter at Great Falls ; 

 Spanish Coulee, 12 miles east of Cascade, Cascade County, Montana. 



SEQUOIA AMBIGUA Heer 



Sequoia ambigua Heer, Fl. Foss. Arct., vol. 3, 1874, Abth 11, p. 78, pi. xxi, 

 figs. 1— 1 1. 



Locality. — Railroad cut west of smelter, north side of Missouri 

 River at Great Falls, Montana. 



SEQUOIA REICHENBACHI (Geinitz) Heer 



Plate XII, Figs. 7, 8 



Sequoia reichenbachi (Geinitz) Heer, Fl. Foss, Arct., vol. 1, 1868, p. 83, pi. 

 xliii, figs, id, 2b, 5«. 



The collection made at Skull Butte, eastern Fergus County, con- 

 tains a considerable number of rather fragmentary branchlets that 

 appear to belong to this species, though the leaves are rather more 

 spreading than is usual in S. reichenbachi. It is not, however, 

 greatly different from certain of the forms referred to it by Heer 

 from the Lower Cretaceous of Greenland. 1 There is also with these 

 branchlets a very fragmentary cone that may belong with them ; it 

 is too much broken to figure. 



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

 of Stanford, Fergus County, Montana.
