3IO CYATHEACEx'\E [ch. xxxiii 



proto-leptosporangiate Superficiales, constituting lines of further advance 

 which will be seen to run parallel to those derived from the primitive 

 Marginales, They will be held over for detailed examination to Vol. III. 

 They are mentioned here so as to indicate that the Cyatheaceae hold a 

 middle position in the Superficiales comparable to that occupied by the 

 Dicksoniaceae among the Marginales. But the constant feature of soral 

 position stamps the middle terms of the two phyla, represented today by 

 the Cyatheaceae and the Dicksoniaceae, as distinct from the Mesozoic 

 Period onwards.
