The Arun In tracing the boundaries of this district a start may be made at the Surrey border, and a line followed through Roughey Street across St. Leonards Forest, by Stone Lodge and Colegate to Pease Pottage Gate, thence south to Hand Cross, westward over Plummer's Plain to Monk's Gate, across country to the junction of the railways near Plumtree Cross, on to Bashurst and Ludwick, taking the main road to Billingshurst, then leaving it again and crossing the railway to the east of the station, on to Coneyhurst, Broadford Green, Chiltington, Thakeham, skirting Heath Common, through Washington, Highden, Findon, West Tarring and Heene to the sea, a little west of Worthing. This district includes the greater part of St. Leonards Forest, and stretches across the county in its widest part. It is drained by the Arun and a few tributary rivulets. and localities for all the species are given at length in my Flora of Sussex, and the same nomenclature of genera and species is here adopted. Since its publication a considerable number of additions have been made. 53
