found almost impossible to preserve them. Professor Heer considers this 
plant equivalent to that described by Lesquereux (Cretaceous Flora, p. 52, 
Pl. I, figs. 8, 11-11f) under the name of Glyptostrobus gracillimus, but the 
correctness of this reference I am inclined to doubt, as we find none of 
the characteristic cones of Glyptostrobus gracillimus with the branches and 
twigs of Widdringtonites. But we do find, as described elsewhere, cylin- 
drieal cones, 5° or more in length, associated with the twigs of a somewhat 
different plant, which, if twigs and cones go together, is a Sequoia. The 
cones and fruit of that plant are figured on Pl. EX, figs. 1-3, and we regard 
them as more closely allied to Heer’s Sequoia fastigiata, as illustrated in his 
Flora Fossilis Arctica, Vol. VII, Pl. LI, fig. 12. In this figure a cone is 
represented which is referred by Heer to his Geinitzia hyperborea; but just 
such a cone we find associated with the branches of Glyptostrobus gracillimus 
(which is certainly not a Glyptostrobus) in both the Dakota sandstones 
and the Amboy Clays, and no certain evidence of the presence of Geinitzia 
has been found in either. 
Hereafter, when more specimens of Widdringtonites Reichit shall be 
collected and better means of preserving them be discovered, we may hope 
from the abundance of the plant to obtain all desired information as to its 
structure and relations. 
In fig. 8 on Pl. VIII it will be seen that two minute cones are borne 
on the end of one of the twigs. These are probably very young fertile 
cones, but they may be immature pollen-bearig organs.
