 branch. 



It is pointed out that certain Lepidodendra (Z. vascii-

 specimens adduced in support of the cone theory are 

 shewn to be explicable on the branch theory. 



Finall}', I wish to express my thanks to Dr. Ho} le 

 for allowing me to describe the Manchester Museum 

 specimen, and to Professor VV. Boyd Dawkins in whose 

 department the work has been done.
