This very handsome species of the very beautiful genus Swain- 

 sonia has been raised from seeds sent from Western Australia 

 by Mr. Wm. Thompson, of Ipswich, from whom we received 

 specimens in the summer of 1804. Our earliest knowledge of 

 it was from specimens gathered by Mr. Bynoe at Depuech 

 Island, and abundantly in sterile places in Nichol Bay, during 

 Gregory and Ridley's Exploring Expedition, both in North 

 Australia. Drummond also appears to have gathered it in West 

 Australia (as it has been raised from his seeds, and first blos- 

 somed in 1863), and Mr. Oldfield gathered it in the Murchison 

 river. 



Of this genus (including Cijclogyne of Bentham and Diplolo- 

 bium of Mueller) fourteen species have been published by Mr. 



JANUARY 1ST, 1865.
