BOTHKODENDRON. 



167 



Mr. Seward 1 has concluded that while some of the characters of 

 these specimens do not agree in detail with those of Bothro- 

 dendron, this probably may be explained by taking into account 

 the partially decorticated nature of the fossils, in which state there 

 would naturally be no trace of the parichnos scars or of the 

 ornamentation of the bark.

The apparently dichotomous branching in these specimens is an 

 argument in favour of referring them to the Lycopodiales rather than 

 to the Gymnosperms. The same author has also concluded that the 

 South African fossils bear so close a superficial resemblance to 

 Bothrodendron kiltorken&e (Haughton), which occurs in the Devonian 

 rocks of the South of Ireland, and of Bear Island in the Arctic
