Description. — " S. ramis elongatis, foliis decurrentibus, patentibus, 

 falcato-incurvis, rigidis, acuminatis." — Heer, 1869. 



This is one of the most wide-ranging fossil plants, both geologically 

 and geographically, that is known, and it seems very probable that it is 

 of a composite character, the well-known difficulty of distinguishing 

 between coniferous twigs of this character prohibiting any satisfactory 

 segregation. Described originally as a species of Araucarites certain of 

 these remains from the Staten Island Cretaceous have shown by their 

 vascular structure that they are related to the Araucarieai, while on 

 the other hand a large number of exactly similar remains of leaf-bearing 

 twigs bore cones which are unquestionably those of a Sequoia. Twigs 

 of this sort are abundant throughout the Potomac Grroup occurring also 

 in the Puson formation of the Black Hills, the Kootanie of Montana, 

 the Shasta of California, the Kome beds of Greenland, and the Neoco- 

 mian of Central Mexico. Abroad they have been reported from the Upper 

 Jurassic (?) of Portugal, the Neocomian of Belgium, the Barremian 

 of Silesia, and the Albian of Switzerland. Similar remains have also 

 been described from a large number of horizons in the Upper Cretaceous, 

 both in this country and abroad.
