penninervis, Pithecolobium pruinosum, Abrophyllum ornans, etc. 
with the Tree Fern, Alsophila australis. 
On the summit are to be found the Syncarpia laurifolia, 
Leptospermum flavescens, Acacia juniperina, the prickly shrub, 
Oxylobium aciculiferum, and a eucalyptus which I have been unable 
to identify. Xanthorrhea arborea is entirely confined to this 
mountain, the genus being represented in other parts of the 
district by X. quadrangulata. 
On the western side of the range is a projecting spur whose 
summit is crowned with steep cliffs partly composed of a 
ferruginous sandstone. Here is the home of the beautiful 
Dendrobiums, D. speciosum and D. monophyllum, with the pretty 
Bulbophyllum minutissimum, spreading over the surface of the 
perpendicular rocks. Here also grow the newly-discovered 
species of Hoya,—H. Keysii, trailing over the cliffs; Zieria 
Smithii, Prostanthera incisa, and P. ringens, all of which seem 
to be confined to this particular spot. 
On the low ground and the hilly country, the chief plants 
of interest are the cycads and macrozamias, Hrythrina vesper- 
tilio with its showy orange colored flowers and the graceful 
Acacia Bidwilla. 
It may be worthy of notice that the terrestrial Orchids of the 
district seem to be almost entirely confined to the slate and 
granite soils, only one species (Dipodiwm punctatum), out of 
the twelve enumerated, having been found elsewhere. 
Of the plants mentioned in this paper, it will be observed that 
a few are entirely new to science, and that several others are 
either very rare or have not hitherto been found in the 
colony. 
I cannot conclude these remarks without expressing in some 
degree my feeling of obligation to the Colonial Botanist, Mr. 
Bailey, for his unvarying kindness to me in all matters con- 
nected with this subject.
