NOTE ON THE FRUCTIFICATION OF PHLEBOPTERIS 

 . ALETHOPTEROIDES, ETHERIDGE, Fil., FROM THE 

 LOWER MESOZOIC BEDS OF QUEENSLAND. 



By R. Etheridge, Junr., &c. 



In the " Proceedings '' of this Society for last year '*' I gave a 

 description of a fern from the Lower Mesozoic beds of the 

 Darling Downs, to which the above name was given, but up to 

 that time no trace of the fructification had been observed. On 

 looking over some miscellaneous fossils in the collection of the 

 Mining and Geological Museum, Department of Mines, I found 

 a few additional examples of this species, one of which shows 

 the fructification distinctly. 



In the genus Phleho^jteris the sori are borne at the ends of 

 certain of the nervules, which do not reach the margin of the 

 pinnules, but are arrested half-way.f This is exceedingly well 

 shown in Brongniart's figure of P . i^olypodioides ',X and although 

 these smaller nervules cannot be distinguished in the present 

 specimen, from its condition of preservation, the position of the 

 sori is similar to that given in the figure quoted.
