Flindersia australis. Tab. 1. 



A tree of moderate size, observed September, 1802, both in flower and with 

 ripe capsules, in the woods and thickets near the head of Broad Sound, on the 

 east coast of New Holland, in about 33° S. lat. The examination of Broad 

 Sound was completed at the same time by Captain Flinders, to commemorate 

 whose merits I have selected this genus from the considerable number dis- 

 covered in the expedition, of which he was the able and active commander.
