EXPLANATION OF PLATE XXV. 
Bleclmoxxjlon talbrcigarense, Eth. fil. 
Fig. 5. An internode, partly in the round and partly as an impression, 
and two nodes, the latter with fronds attached in a greater or 
less degree. In the centre of the internode is a small protuber- 
ance that may be the base of attachment of an adventitious 
root. The fronds on the right have been pressed back out of 
the normal position, and all have suffered from the disintegra- 
tion of their parts by weathering. One of those on the left 
has been so much decomposed that only the outline remains, 
with the revolute margin subdivided by the impressions of 
the veinules ,* * 3£.
