NATURAL HISTORY.

served in the collections of the late voyages, all small trees, 
and one half of which has been gathered on the North-west 
Coast. 
A species of Morns, bearing small white fruit, was dis- 
covered upon the continent and islands of New South Wales, 
within the tropic, where also a new genus of the order, with 
radiated leaves, has been traced as far as Endeavour River. 
Of the genus Urtica, whose numerous species can simply 
be considered as of herbaceous duration, although a few of 
tropical existence assume a fruticose habit, there is one 
plant in the vicinity of the Colony of Port Jackson, remark- 
able for its gigantic, arborescent growth ; many specimens 
having been remarked from fifteen to twenty feet in height, 
of proportional robust habit, and of highly stimulating 
nature. 
Santalace^. — Nearly three-fourths of the Australian 
portion of the order described, were formerly discovered in 
the parallel of Port Jackson, upon the shores of the South 
Coast, and in Van Diemen’s Land. The genus Choretrum, 
however, heretofore limited to the southern extremes of the 
continent, approaches within about two degrees of the tropic 
on the West Coast, having been lately observed on Dirk 
Hartog’s Island. It is rather remarkable that neither Lep- 
tomeria nor Choretrum form a part of the feature of the ve- 
getation of the arid, depressed portions of the North-west 
Coast*, where several of the more harsh, rigid kinds of plants, 
of various genera, of the South Coast have been remarked. 
Those extensive shores (generally speaking) are not wanting 
in the order, for two species of the tropical genus Santalum, 
Exocarpus, and a globular-fruited Fusanus, were collected in 
and about the parallel of 15° South.
