16TH JUNE.--Proceeding nearly north-west, we met with the little river I had discovered a few miles beyond my camp of the 13th and 14th instant. The distance of this point from the camp we had left this morning was about 21/2 miles. We crossed it, and turned to the westward, and even south-west, to avoid it. Over its extreme south-western bend there was a little rocky hill, which I ascended, and thence saw a mountain I had intersected from the high station east of the depot. It now bore 12 deg. west of north, and I directed my course towards it, as well as the country would permit. We crossed several sandy ranges on which the callitris was, as usual, the chief tree, as it was also on the soft heavy sand between them. Occasionally, the lowest parts where water would take its course, consisted of firm clay, and we took advantage of such flats, when their direction was favourable. I was at length under the necessity of encamping on one of these, where there was no water, nor any to be found in it after I had followed it down four miles. In my search for water, I found a curious new PHEBALIUM.[*] Thermometer, at sunrise, 43 deg.; at 9 P. M., 54 deg.. Height above the sea, 1646 feet. [* P. GLANDULOSUM (Hook. MS.); foliis angusto-lineari-cuneatis retusis canaliculatis marginibus revolutis subtus ramulisque argenteo-lepidotis superne (praecipue) grosse glandulosis nudis, corymbis terminalibus parvis sessilibus fusco-lepidotis, calycibus subtruncatis, petalis ovatis concavis. Allied to P. SQUAMULOSUM and P. ELOEAGNOIDES, but very distinct, especially in the presence of the large semipellucid hemispherical glands, seen more or less in various parts of the plant, but very conspicuous on the upper side of the leaves.]
