Rain had fallen during the night but the day was favourable though cloudy. I ventured on a straight line through the sand and bushes of Eucalyptus dumosa in order to cut off some miles of our beaten track, which was nearer the river and rather circuitous. We crossed some sandhills, the loose surface of which was bound down only by the prickly grass already described. From these hills the view was extensive and bounded on all sides by a perfectly level horizon. On one of them a solitary tree drew my attention and, on examining it, I discovered with much satisfaction that it was of that singular kind I had only once or twice seen last year in the country behind the Darling. The leaves, bark, and wood tasted strongly of horse-radish. We now obtained specimens of its flower and seed, both of which seemed very singular.* By the more direct route through the scrub this day, with what we gained yesterday, we were enabled to reach, at the usual hour for encamping, the red cliffs near the spot where we formerly met the second division of the Darling tribe. I took up a position on the western extremity of the broken bank, overlooking an angle of the river, and commanding a grassy flat where our cattle would be also secure. The weather became very boisterous after sunset, and our tents were so much exposed to the fury of the wind that at one time I thought they would be blown into the river. The waters continuing to rise, the Murray now poured along nearly on a level with its banks, and how we should cross or avoid: The mosses, waters, slaps, and stiles that lay between us and the depot, if the river rose much longer, was a question for which I was prepared. On the other hand the very cold and boisterous weather was in our favour as being opposed to any assembling of the tribes at points of difficulty along the line of our track, as they certainly ought to have done as good tacticians, for they never lost sight of our movements while we were in that country.

The capsules are arranged in a single verticillus and consequently this species will belong to Gyrostemon as distinguished from Codonocarpus by Mr. Endlicher.)
