Roots and Rootlets of Uncertain Affinity. 



Specimens of roots or rootlets are occasionally found associated 

 with members of the Glossopteris flora. Some of these no doubt 

 may be attributed to Vertebraria, while others belong to plants 

 whose nature it is impossible to decide. Some of the specimens 

 to which Dana gave the names Austrella rigida, 1 Confervites(?) 

 tenella, 2 Cystoseirites, sp., 3 are probably of this nature. The term 

 Pustularia calderiana, Royle, 4 is a nomen nudum.
