 Remarks. Common in all coalfields. Pinnularia has been found 

 attached to Calamites as their rootlets, but probably the fossils usually 

 included under Pinnularia capillacea may also be the rootlets of other plants. 

 Asterophyllites tenella, Rb'mer (Palaeontographica, vol. ix. p. 20, pi. v. fig. 3), 

 is probably only one of the many forms of Pinnularia capillacea.
