were surrounded by closely packed microsporophylls on which the 
remains of microsporangia could be seen*. Examination of this 
specimen and comparison with other examples of the same 
type, leave no doubt as to the correctness of Lignier’s inter- 
pretation. 
But while discussion and speculation were proceeding about 
these forms, a specimen in the Yates collection in the Paris 
museum remained unnoticed, although it presented the cast of an” 
indubitable male flower, and probably belonged to the species

the original] tissues are left as faint carbonaceous markings which 
are associated with patches of white Scarbroite, and the example 
undoubtedly originated from the cliffs of Runswick or Hawsker
