Leaves of extremely large size with lobes similar to the normal 

 lobes in the leaves of the existing species. Saporta's leaf is only 

 slightly larger, however, than the modern leaf shown in PI. 2, 

 Fig. 6. 



The Eocene and Oligocene forms are very similar, what little 

 differences are apparent being probably due to the careless drawing 

 of the leaves from the Paris basin. Saporta's figure, however, 

 does show a few serrations on some of the lower lobes which are 

 wanting in its Eocene ancestor, if we may draw such a conclusion 

 from the small amount of material available for study. I was at 

 first inclined to keep these two leaves separate, appearing as they 

 do at such different horizons, but there are a number of other iden- 

 tical spe('i(\s from the two horizons, and others with even a greater 



above indicatt'il. It is, ot course, w itliiii the range of possibility that

 Schiinper note^ tlie resemblance of these lea\es to such Pro- 

 teaceous forms as those of Banksia cjrandis and repcns of Robert 

 Brown, but the resemblance is much closer to the large leaves of 

 the modern Comptonia. Saporta in his revision of the Aix flora 

 records this species from that locality and notes its resemblance to 

 Myrica aciileata.
