 Devonian Plants," p. 7). 



I do not think it can be claimed that the true systematic position of the genius 

 Ptilophyton, Dawson, has yet been clearly determined. The late Sir William Dawson 

 included five species in his genus Ptilophyton* These were : — 



1. Ptilophyton pennseformis, Goppert, sp.f 



2. Ptilophyton Vanuxemi, Dawson, sp.J 



3. Ptilophyton plumula, Dawson, sp.§ 



4. Ptilophyton Thomsoni, Dawson.|| 



5. Ptilophyton lineare, Lx., sp.1T
