The Scudder collection contains a fine specimen belonging to this 

 species, which is much better than the type upon which it was based. 

 It includes two short ''spurs" a centimeter in length, each bearing a 

 cluster of five leaves. None of the leaves is entirely preserved, how- 

 ever, the longest being only retained for 4.5 cm. of its length, which, 

 according to the original description, was 12 cm. or more. 



A fragment of a cone has been attributed to this species by Professor 

 Cockerell, but it is purely conjectural as to whether it belongs here or 

 to the better known P.Jlorissanti. The only cone found in the collec- 

 tions under consideration is referred to the latter species.

With the exception of the dictotyledonous leaves referred to the 

 several species of Myrica or Fagopsis, this coniferous plant is possibly 

 the most abundant form found at Florissant. It occurs in pieces of 

 all sizes, from single slender twigs up to forking branches and branch- 

 lets covering a square foot or more in area, and often preserved in a 

 high degree of perfection. The branches and branchlets with the 

 two quite distinct kinds of leaves, the male aments and the mature 

 cones are aU known in completeness of detail but Httle inferior to 

 Uving material. 



That this conifer is the form described by Lesquereux imder the 

 name of Sequoia affinis, there can, of course, be no doubt, nor can 

 there be any question as to the identity with it of the material de- 

 scribed and figured by him as Glyptostrobus ungeri Heer. That it is 

 properly referred to the genus Sequoia is also reasonably certain, for 

 as Cockerell and others have pointed out, it is of the type of the living 

 S. sempervirens, and is not a Glyptostrohus. I quite agree with 

 Cockerell that there is probably only a single species of this type of 

 conifer present as Florissant, and for this it seems to me the available 

 name is Sequoia affinis.
