MS.); foliis alternis glaucis lineari-lanceolatis breviter tenuiter petiolatis subfalcatis utrinque acuminatis reticulatovenosis, nervis lateralibus marginem prope, racemis paucifloris axillaribus, calyce turbinato in pedicellum brevem attenuato.] 10TH MAY.--Continued nearly northwards, over fine open forest land. The sprinkling of mountains of peculiar forms here and there, and the open country, which showed a bluey distance, were new features in the scenery, and most pleasing to us, so long accustomed to travel through a level woody country. The visible possibility of overlooking the country from any eminence, is refreshing at all times, but to an explorer it is every thing; besides he is not half so much in danger of wanting water, when in the neighbourhood of mountains: with these sentiments I went forward this morning, even although rather despairing of seeing more of our friendly river. We crossed two chains of dry ponds, apparently some of its highest sources. Still I travelled steadily towards a fine mountain before us, over open downs, but with scrubs on either side. Reaching a dry bushy hill S. E. of the mountains, about the time we should have encamped, I perceived that the country sloped most to the eastern side of it, which was rather out of my course; for the sake of finding water more readily I got into a water-course falling that way, and followed it down. This, opening soon into grassy flats, enabled us to avoid the scrubs. The welcome white-trunked Eucalyptus next over-hung the holes of the water- course, and the valleys spread into beautiful open plains, gracefully fringed with Acacia pendula. Still, the ponds were dry. I crossed a bare grassy eminence, and, where several channels met, I saw luxuriant white trunks; heard and saw many cockatoos of the same colour (PSITTACUS GALERITUS); and found there an abundant pond of water, beside which we encamped. On some of the Eucalyptus trees grew a beautiful Loranthus, which was new to us; it proved to be one formerly discovered by the indefatigable Allan Cunningham, but only now described by Sir William Hooker.[*] Thermometer, at sunrise, 28 deg.; at 4 P. M., 76 deg.; at 9, 38 deg.;-- with wet bulb, 34 deg.. [* L. NUTANS (All. Cunn. in Hook.
