The singular genus to which this species belongs is ex- 
clusively Australian. Six species only are described by Dr. 
Brown, but many more are known, and their number will 
probably be found considerable. It is remarkable for the 
great quantity of delicate knotted hairs with which the 
densely spiked or capitate flowers are covered. 
That now figured, the first which has been known to 
flower in Europe, was raised from Swan River seeds by 
Robert Mangles, Esq. of Sunning Hill; I possess wild speci- 
mens from the same country, for which I am indebted to 
* rpíxiwoc, composed of hairs, in allusion to the shaggy flowers.
