in the middle, they look, at first sight, like the fruit dots placed 
on both sides of the medial nerve of a Pecopteris, whose derma 
or foliaceous tissue has been entirely destroyed. As no trace of 
_ this tissue can be seen, as the pedicels do not resemble veins, 
but are curved in a peculiar way, and as the fruit dots are at 
some places scattered and not in regular order, this fossil raceme 
is more likely the fruit-bearing part of a species whose sterile 
frond is possibly known with other characters. If it is so, this 
species would have a relation to the genus Aneimia of the living 
ferns, and thus, it could not enter into any of the three general 
divisions mentioned above.
