We crossed Byrne's creek, near a cattle station called Lagoura, and after keeping its banks for four miles further (having for that distance granitic hills on our right) we finally quitted it, and passed over a grassy plain of the same kind of soil and character as those extensive level tracts seen during our last journey but having, what seemed singular to our unaccustomed sight, a coating of green herbage upon it. NEW PLANTS. In our progress I found no fewer than three new species of the pretty genus Trichinium;* a small species of Sida before undiscovered, with minute yellow flowers,** and also a fine-looking acacia with falcate leaves, singularly white or rather silvery, and with drooping graceful branches.*** (*Footnote. 1. Tr. alopecuroideum, Lindley manuscripts; caule ramoso glabro, foliis lanceolatis glabris subtus scabriusculis, spicis cylindraceis elongatis, bracteis rotundatis, calycibus herbaceis sursum calvis acutis, rachi pilosa, cyatho staminum dentato. 2. Tr. parviflorum, Lindley manuscripts; foliis ovatis acutis petiolatis subtus et caule furfuraceo-tomentosis, spicis gracilibus elongatis, bracteis acuminatis scariosis, calycibus lanatis, rachi lanata, staminibus inaequalibus distinctis. 3.

S. corrugata, Lindley manuscripts; incana, prostrata, pusilla, foliis subrotundis angulatis cordatis palminerviis serratis, pedunculis 2-3 filiformibus petiolis longioribus, fructu disciformi corrugato, coccis monospermis commissuris muricatis.) (***Footnote. This proved to be a very distinct, undescribed species. A. leucophylla, Lindley manuscripts; gracilis, ramulis filiformibus angulatis albido-sericeis, phyllodiis lineari-lanceolatis falcatis apice uncinatis obscure 2-nerviis appresse et densissime sericeis: margine superiore basi subglanduloso, racemis umbellatis axillaribus phyllodio multo brevioribus.) REACH THE LACHLAN. Travelling four miles more across level forest land, we reached the banks of the Lachlan at Waagan,* a cattle station a mile and a half below the junction of Byrne's creek of Oxley, which we had just traced in its course from Buree. (*Footnote. Waagan means a crow in the native language.) FIND ITS CHANNEL DRY.
