It will be seen, by an inspection of the map, that there is a large interval of low depressed country, between Stanley"s and Grey"s Ranges.
The rock formation on the latter being almost exclusively of one kind.
Beyond Grey"s Range, no elevation in the interior, on the N.W. line traversed by the Expedition, was seen; but on the Stony Desert the fragments of rock, with which it was covered, were composed of indurated quartz, rounded by attrition, and coated with oxide of iron. North of the Stony Desert, sandstone occurred in the bed of Eyre"s Creek, and milky quartz cropped out of the ground, in lat. 25 degrees 35 minutes, and in long. 138 degrees 39 minutes. The valley of Cooper"s Creek was, however, bounded in by low quartzose hills, covered with sand. The general level of the interior was otherwise ferruginous clay, on which the long sandy doones or ridges rested, excepting where their regularity was broken by flooded plains. The clay rested on sandstone, which, with a few exceptions, where fossil tertiary limestone occurred, similar to that of the Murray cliffs, was ferruginous sandstone, at the depth of two feet and a half or three feet.

BOTANICAL APPENDIX ROBERT BROWN, ESQ., D.C.L., F.R.S., F.L.S., &C.
My friend, Captain Sturt, having placed at my disposal the Collection of Plants formed in his recent Expedition into the Southern Interior of Australia, I am desirous of giving some account of the princ.i.p.al novelties it contains.
The collection consists of about one hundred species, to which might be added, if they could be accurately determined, many other plants, chiefly trees, slightly mentioned in the interesting narrative, which is about to appear, and to which the present account will form an Appendix. I may also observe, in reference to the limited number of species, that Captain Sturt and his companion, Mr. Brown, seem to have collected chiefly those plants that appeared to them new or striking, and of such the collection contains a considerable proportion.
In regard too to such forms as appear to const.i.tute genera hitherto undescribed, it greatly exceeds the much more extensive herbarium, collected by Sir Thomas Mitch.e.l.l in his last expedition, in which the only two plants proposed as in this respect new, belong to genera already well established, namely, Delabechia to Brachychiton, and Linschotenia to Dampiera.
In Captain Sturt"s collection, I have been obliged, from the incomplete state of the specimens, to omit several species, probably new, from the following account, in which the plants noticed, chiefly new genera and species, are arranged according to the order of families in the Prodromus of De Candolle.
