622 NOTES ON THE NATIVE FLORA OF NEW SOUTH WALES. By R. H. Cambage, F.L.S. Part ix. Barraba to Nandewar Mountains and Boggabri. (Plates Ixvi.-lxvii.) The notes for this paper were obtained during a short visit to the locality in November, 1909, and although many small plants were doubtless overlooked, sufficient were noticed to enable a good general impression of the character of the vegetation to be formed. One of the chief features of interest of the locality, from a geographical standpoint, is that, although the Nandewar Mountains are situated about 90 miles west of the Great Dividing Range, and are connected with New England by the Nandewar Range, which is in places a comparatively low spur, yet they reach an altitude of about 5,000 feet above sea-level, an elevation only exceeded in a few instances in New South Wales, outside the Kosciusko and surrounding area. It is this elevation, and partial isolation, which give additional interest to the locality from a botanical point of view, for the increased height enables plants to flourish thei'e, which would otherwise be absent from the district; while the isolation makes it both difficult and inter-esting to account for some of the species being there at all. The Nandewar Mountains were discovered by Surveyor-General Oxley on the 8th August, 1818, when on his exploratory journey easterly from the Macquarie River to Port Macquarie. As an evidence of their comparative height, and the generally lower nature of the intervening country, they were first seen and named from a distance of upwards of one hundred miles. Oxley had just previously discovered the Warrumbungle Mountains, which he named Arbuthnot's Range, and he writes, that when standing on Mount Exmouth, the highest point of the Warrum-
