On the Ditchling Road, and the Roman Encampment on Hollingbury Hill, Wild Mignionette, Heath, Thyme, Gentian, Whitlow-grass, Carline and Plume Thistle, and Hawkweed grow in profusion; and in the fields immediately south of the pond there, Dandelion, Adam’s Needles, Centaury, Convolvulus, Yellow Snapdragon, Yarrow, Cockle, Perriwinkle, Poppy, Milkwort, Dropwort, Cropwort, Fleabane, Yellowwort, Henbane, and Groundsell form a pleasing diversity; while, in the copses contiguous, the Rock Rose and the Sun Rose give their Summer refreshing odours. In speaking of the Mosses in the vicinity of Brighton, the area will be restricted to the range of the Downs in which the Town is placed, and the coast line of the same distance. Therefore, assuming the limit to be bounded on the east by the Cliffs as far as Newhaven, and the Downs that slope to the west side of the river Ouse, and gradually heighten until passing Lewes, Offham and its chalk-pits are reached. Following, then, the base of the hills by the Devil’s Dyke, and the Fulking Downs to Beeding, and thence continuing the marginal line to Shoreham, a tract of country will be embraced, that will be bounded on the south by the sea-shore. Thus, the sandstone plants, and those found in arenaceous soil will be represented by the species from the banks on the beach, near Aldrington Basin, and a few from the tertiary sandstone at Newhaven Cliffs—chalk, clay, and argillaceous soils determining the remaining species.
