334 SOME NEW SOUTH WALES PLANTS ILLUSTRATED. 



An examination of the hermaphrodite flowers sliowed that some 

 of the stamens at the base of the ovary were sterile, although in 

 external appearance they resemble the fertile anthers of the 

 staminal column of male flowers on the same tree. The anthers 

 of flowers from trees with exclusively male flowers are somewhat 

 smaller. 



I wish to acknowledge my indebtedness to Mr. J. H. Maiden, 

 F.L.S., for his kindness in allowing me the use of his herbarium.
