 WEST AUSTRALIAN PLANTS. 



By Baron von Mueller, K.C.M.G., M.D., F.R.S. 



Ptilotus Macleayi. 



Leaves small, from narrow- to ovate-lanceolar, flat, decurrent on 

 their petiole, as well as the slender branchlets glabrous ; spikes 

 capitular, on short peduncles; flowers small, pale; bracts and 

 bracteoles nearly as long as the calyx, glabrous, from a blunt 

 base lanceolar, by theii' carinular venule conspicuously extended 

 into a setaceous acumen ; sepals lanceolar-elliptical, streaked in 

 their lower portion, quite glabrous outside, the three inner 

 beard-like invested inside towards the base with crisped hairlets ; 

 stamens much shorter than the sepals, or one only elongated; anthers 

 dark-brown, blunt-ellipsoid ; pistil glabrous ; seed dark-brown 

 or black, very shining, smooth. 



Near King's Sound ( W. Froggatt). 



Leaves flat, equally green on both sides, J-1^ inches long, not 

 seldom some opposite-approximated ; spikes in age short-cylindric ; 

 flowers hardly as long as those of P. sjncatics. Rhachis subtle- 

 cottony invested. Filaments tender-capillary. Style rather 

 elongated ; stigma minute, undivided ; fruit narrowly hemi- 

 ellipsoid, pointed ; seed about one-twentieth inch long. 



Named in honour of our great entomologist and ichthyologist, 

 who generously placed his collector's botanic material at the 

 writer's disposal. 



The same plant is contained also in a collection of botanic 

 specimens recently formed by Staff-surveyor Mr. Nynlasy 

 near the Ord-River, and presented by the Hon. John Forrest 

 to the Melbourne Phytologic Museum. The feature of the 

 plant is almost that of Allnuinia rwdi/lora; but the pericarp
