We do not trace our plant in any published species; nor 
find it in the Banksian or Lambertian Herbariums. It is 
said to be of very late introduction from the Cape of Good 
Hope. The flowers, in all the plants we examined, were 
provided with only a slight rudiment of a pistil in the midst 
of the natural quota of perfect stamens; whence we have 
assumed them to belong to individuals of the barren side of 
a dioicous species, and of which the fertile plant is still un- 
known to us, affording, as far as our acquaintance with the 
subject extends, an anomalous instance in the genus,
