I have also seen twigs of plants grown by Mr. Williams 

 at Werrington, and we have in the Royal Botanic Garden 

 several plants — some of them flowered in 1915 — which were 

 raised from seed collected by Mr. Forrest and presented to 

 the Garden by Bees, Ltd. Tlie plant is hardy and an 

 interesting addition to our small yellow-flowered garden 

 species. I notice that some of these living plants have not 

 shed their leaves after the first season. 



Mr. Forrest tells me the plant is abundant on the Tali 

 Range.
