EUCALYPTUS TREES. 151 
A prominent aspect in the vegetation of south-west 
Australia emanates from the comparatively large num- 
ber of singularly beautiful Banksia-tree, preponderant 
there as the arborous Grevilleg in North Australia. 
The existence of but two of that genus, Banksia Aus- 
tralis, and B. ornata, in the extensive tract of interior 
and coast land, from the head of the Australian Bight, 
to the vicinity of Port Philip, renders the occurrence 
of an increased number of trees of this kind in East 
Australia again still more odd. Rutaceous and good- 
eniaceous plants, though in no part of the Australian 
continent rare, attain in the south-west their greatest 
numerical development, and should not be passed si- 
lently, or, like Epacridezx, as merely ornamental plants, 
though still so rare in our gardens ; but these elegant 
plants deserve also attention for their diaphoretic prop- 
erties, or for the bitter tonic principle which pervades 
nearly all the species of the two orders. Stylidez are 
here still more numerous than in our north, and com- 
prise forms of great neatness; while sundews (Dro- 
sere) are also found to be more frequently than in 
anyo ther part of Australia, and indeed of the globe. 
When, glittering in their adamantine dew, they re- 
appear as the harbingers of Spring from year to year, 
they are greeted always anew with admiration. But 
the greatest charm of the vegetation consists in the 
hundreds of myrtaceous bushes peculiar to the west, 
all full of aromatic oil ; among these again, the feath- 
er-flowered numerous Verticordig, the crimson Calo- 
thamni, and the healthy Calythrices vie with each 
other as ornaments, Still also of this order many gor- 
geous plants exist in other parts of, especially extra- 
tropical Australia, The numerous bushes of Legu,
