GOODENOVIAE. The Herbarium contains very few specimens of this considerable Australian family, the greater mass existing in and to the southward of the parallel of Port Jackson. The order is reduced to Goodenia, Scaevola, Velleia, and the tropical Calogyne on the North-west Coast, and the few species of the two first genera prove to have been formerly discovered upon the South Coast during the voyage of Captain Flinders, of which one plant has alsa a much more extensive range than has been given it heretofore. It is Scaevola spinescens, which forms a portion of the harsh, rigid vegetables of Dirk Hartog's Island on the West Coast, and from that shore probably occupies a part of a very considerable extent of barren country in the interior, in a direction towards the East Coast, having been seen in abundance in the latitude of Port Jackson, so near that colony as the meridian of 146 degrees 30 minutes East. A new Velleia, discovered on the North-west Coast in latitude 16 degrees, augments that genus, belonging to the section with a pentaphyllous calyx. RUBIACEAE. The existence of several plants of this extensive family in the intratropical parts of Terra Australis especially when aided by some individuals of almost wholly exotic tribes, that form a prominent feature in the Flora of other equinoctial countries, tend, in some measure, to diminish the peculiar character of the vegetation of Terra Australis on those shores, and thus it is a considerable assimilation to the Flora of a part of a neighbouring continent that has been traced. About thirty species are preserved in the collections of these voyages, for the most part belonging to genera existing in India, but more abundant in the tropical parts of South America. Of these, Gardenia, Guettarda, Cephaelis, Coffea, Psychotria, and Morinda, are found on the East Coast; whilst, in corresponding parallels on the opposite, or north-western shores, the order, although not materially reduced, is limited to the two latter genera, with Rondeletia, Ixora, and Genipa. It is worthy of remark, that the range of Psychotria, which has not been observed beyond the tropics in other countries, extends in New South Wales as far south as the latitude of 35 degrees; at the western extremity of which it does not appear to exist.
