58 FOSSIL PLANTS. 



from fragmentary specimens in which the bracts had been removed, causing 

 the sporangia to be exposed, it is of the greatest importance that specimens 

 in this condition should be secured. Often their beauty is not such as to 

 attract the attention of the general collector ; but as these specimens are of 

 the greatest value to those working out the minute structure of fossil fruits, 

 it is to be hoped that all who have the opportunity will carefully collect 

 them. 



Those interested in this group of fossils would do well to consult the 

 " Steinkohlen-Calamarien " by Weiss.
