A HISTORY OF SUSSEX 



There is perhaps a greater diversity of soil in this district than in any other. In the 

 north we have sands and sandstones alternating with beds of clay, and on these St. Leonards 

 Forest of about 10,000 acres, in which many interesting plants previously referred to occur. 

 The marsh and bog lands at the foot of the Downs, as at Chiltington Common, contain 

 numerous species which delight the botanist, such as Utricularia minor, formerly questionable 

 in Sussex, Potentilla Comarum, Menyanthes trifoliata, Hydrocharis Morsus-rancs, and Pilularia 

 glohulifera, rare in the county. Further south are the Amberley Wild Brooks, in the valley 

 of the Arun, an immense marshy tract for Sussex, which when flooded in winter resembles 

 a lake in dimensions. Here grew formerly the black crowberry, Empetrum nigrum, perhaps 

 not extinct, and the cranberry, Faccinium oxycoccos, now rare, but which formerly so abounded 

 that its fruit sold at a shilling a quart, and here are to be found Stellaria glauca, Hypericum 

 elodes, Myrica Gale, Viola palustris, Eriophorum vaginatum, and Carex teretiuscula. Vegetable 

 mould here first appears, and then from four to five feet of peat on a dark blue silt or clay. 



The banks of the Arun well repay investigation, and near Arundel, on both sides of the 

 river affected by the tide, we have Scirpus carinatus and S. triqueter, both very rare, the latter 

 being found only by the Arun and the Thames. Clymping Sands near its mouth afford 

 good botanising.

III. The Adur 



The confines of this district are the Arun boundary from the sea to Plummet's Plain, 

 and thence the Ouse boundary to Rottingdean and the sea a little east of Brighton. It is 

 drained by the Adur, whose e.astern and western waters coalesce about a mile and a half 

 west of Hcnfield, and by its numerous tributaries ; also by the Wellesbourne, a small in- 

 dependent stream which rises near Patcham, and passing by Preston reaches the sea at Brigiiton. 



To the north of the Downs we have that part of the Weald in which Borrcr made his 

 researches, and in which most of his herbarium specimens were collected. The plants of the
