This singular plant is one of the acquisitions from Swan 

 River. Upon its first arrival great expectations were enter- 

 tained of its beauty, in consequence of its flowers being known 

 to be collected in dense heads from which the long stamens 

 project to some distance. Upon producing its blossoms it has 

 however been found that however singular the structure, the 

 total want of brilliancy of colour renders it unfit for cultivation 

 for ornamental purposes. It can only now be regarded as a 

 Botanical curiositv.
