626 ON THE FRUCTIFICATION OF PHLEBOPTERIS ALETHOPTEROIDES. 



In general appearance the fructification of our fossil greatly 

 resembles that of P. crenifolia, Phillips, * but in its minute 

 structure is much like that of P. Schouvii, Brong. f In its 

 present state it possesses a stellate appearance, and occupies a 

 very considerable portion of the surface of the pinnule. It would 

 seem that the indusium had in each case burst, leaving the 

 interiors of the sori exposed, in which case the sporangia are 

 represented by the small radiating sub-divisions. 



The fossil is from the same locality as former specimens, viz.. 

 Darling Downs, near Toowoomba.
