Under this name and as described above, Heer has figured a large 

 number of globose, capsular fruits, to which the one figured here is appar- 

 ently referable. I have seen only two specimens of these fruits from the 

 Dakota Group, both partly emliedded in a hard, ferruginous sandstone and 

 closed, except the upper part of the one figured here, which is parti)' l>roken.
