lately discovered upon the north-western shores of Australia, 
and which are alone worthy of remark here, it is to be 
observed, that, considering the many points of that coast 
visited during the progress of the relative voyages, the 
number of species observed are comparatively few, for, in- 
cluding Eucalyptus, it does not exceed sijcteen plants. Of 
Eucalyptus itself, only seven species were detected on those 
shores, and these, for the most part, form small trees, more 
approaching the average dimensions of all their congeners 
in the colony of Port Jackson. Melaleuca is limited to 
three species, one of which was originally discovered by 
the celebrated navigator, Dampier, on the West Coast, 
where Beaufortia has been recently seen. Four species of 
Tristania, their related genu^, were gathered in about lati- 
tude 15° South, where also an Eugenia, bearing fruit, was 
observed ; but of Leptospermum, or Beeckea, genera chiefly 
belonging to the higher latitudes of New Holland, no spe- 
cies appeared throughout the whole extent of coast ex- 
amined. 
Rhamnea: and CELASTRiNiE were formerly united among 
the Rhamni of Jussieu, but disposed in sections, differing 
from each Other in the position of the stamina, with re- 
lation to the petals, and in the character of the fruit; 
which, when viewed with other important differences of 
fructification, induced Mr. Brown to modify and define them 
as distinct orders. 
In the Herbarium of the voyages, there are a few plants 
belonging to Rhamnus, Ziziphus, Ceanothus, or Pomaderris, 
and Celastrus, but both families prove to be comparatively 
rare in the intratropical parts of Terra Australis, beyond 
which Cryptandra seems only to exist. Upon the north- 
western shores, a species of Ziziphus (common to the East
