In 1916 Professor Cockerell, of the University of Colorado, 
published a brief note* based upon plant material collected from 
the supposed McEIlmo formation of southwestern Colorado. The 
subsequent discovery that this supposed Lower Cretaceous 
flora was stratigraphically above a black shale horizon carrying 
a considerable dicotyledonous flora led to the sending of all of the 
material to the present writer for a more critical study than 
Professor Cockerell was able to devote to it. 
The discussion of the question of the stratigraphic relations 
and age of these two floras is reserved for a subsequent communi- 
cation, the present paper being devoted to the interesting questions 
of habit and distribution derived from a study of the abundant 
relics of Matonidium preserved in the later of the two floras above 
mentioned. 
The Colorado remains, which Professor Cockerell identified as 
Matonidium Althausii, or Matonidium Goepperti as some paleo- 
botanists prefer to call the species on the ground that the older 
and correct name is less familiar, are superficially very much like 
that well-known and rather variable species. Botanists who
