A solitary and very remarkable deviation from the usual natural economy of Loranthus, is observed in a species (L. floribunda) described and figured by M. Labillardiere, which is found on the shores of King George’s Sound, where, in no way recognising the dependent habits of its congeners, it rises from the soil to a tree fifteen feet high, being never remarked relying upon other vegetables for its subsistence. Viscum is found in the colony of Port Jackson, to which it is not confined, having been also gathered at Endeavour River, on the same coast, within the tropic. The southern range of the two genera seems to be nearly beyond the fortieth degree of latitude; but in the northern hemisphere, Loranthus exists in Siberia.
UMBELLIFERAE. The equinoctial portion of the Herbarium contains only three or four plants of this extensive European order, belonging to Hydrocotyle, Azorella of Cavanilles and Labillardiere (from which Trachymene of Rudge is probably not distinct) and a suffruticose plant referred to Cussonia, that have been collected upon the East Coast. Upon the north-western shores, Azorella was alone remarked, of which a species is very general upon its main and islands, and chiefly remarkable for its gigantic herbaceous growth.
MYRTACEAE. With respect to that portion of Myrtaceae, 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, including Eucalyptus, it does not exceed sixteen 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 genus, were gathered in about latitude 15 degrees South, where also an Eugenia, bearing fruit, was observed; but of Leptospermum, or Baeckea, genera chiefly belonging to the higher latitudes of New Holland, no species appeared throughout the whole extent of coast examined.
RHAMNEAE and CELASTRINAE were formerly united among the Rhamni of Jussieu, but disposed in sections, differing from each other in the position of the stamina, with relation 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.
