the peltate expansions of sporophylls B and D , which are also cut very 
nearly parallel to their surfaces. 
It would have been impossible to have determined this point with 
an inferior lens. 
I do not publish an enlarged drawing of this area because it is not

essential for my purpose, and my artistic ability is not sufficient to represent 
it adequately in two dimensions. 
Sporophylls A and B very nearly meet, and the spot where they do so 
corresponds with the place in the Williamson section, where Dr. Lang 
believes them to be confluent. Text-figure 6 is an enlarged drawing of por- 
tions of the two sporophylls where nearest together ; their edges are provided 
with a forest of hairs which interlock. 
Such a region in a crushed and macerated specimen might very easily 
be taken to show actual continuity, as I believe Dr. Lang has done in 
the case of the Williamson section.
