yellow flower-heads ; P. hiloha, whose hranches are some- 

 times covered for six inches together witli feathery flowers ; 

 and P. heterophylla^^^^ a very graceful plant. Another spe- 

 cies, P. hrevifolia,^^* has flowers which, when infused in hot 

 water, give out so brilliant a yellow colour that it is worth 

 examination as a probable source of a dyeing material. 



The Persoonias are plants of little beauty ; P. Frazeri is 

 the handsomest ; P. macrostachya"'^ like Petrophila hrevi- 

 folia, seems to possess dyeing properties that deserve inves- 

 tigation. 



Of Hakea the species are numerous, and generally by 

 no means worth cultivation, H. ruscifolia being the only one
