West Australia. Laverton, scarce, F. A Rod way. 



This genus was hitherto very imperfectly known. It was 

 described by F. von Mueller from very scanty material, collected 

 by Young between Elizabeth River (west of Torrens Lake) and 

 Youldah Water (30° 23' S.L. 131° 47' E.L.) in South Australia. As 

 the genus was represented at Kew only by a single leaf, a branch of 

 Mr. Rod way's plant was sent to Professor Ewart at Melbourne, to be 

 compared with von Mueller's type. He confirmed the determina- 

 tion so far as the genus was concerned, but suggested that it was 

 a distinct species. His notes and a few fragments he was good 

 enough to send prove this to be the case. Mr. Rodway's specimen 

 being so much more complete than F. von Muellers original, an 

 amended description of the genus is here added.
