BOTANY 



chalk, especially in the neighbourhood of Brighton, have been already referred to. To the 

 west of Brighton the Adur flows into the sea at Shoreham. Some low cliffs in the vicinity, 

 composed of sand, gravel, and comminuted shells, afford many interesting species, while the 

 ballast along Shoreham Harbour is the abode of several varieties.

IV. The Ouse 



The limits of this district may be thus defined : We take first the Cuckmere boundary 

 to Cross-in-Hand, and thence follow the East Rother boundary to Castle Hill, near Rotherfield. 

 We then turn westward across the ridge of the Weald to Sand Hill, Stone Cross, Crowboro' 

 Gate, Duddleswell Gate, Sweet Mine Pits, Nutley Hill, Charlwood, Charlwood Gate, Wych 

 Cross, Cold Harbour, Tyne's Cross, West Hoathly, Turner's Hill, Half Smock, across Bal- 

 combe Down and Highbeech Warren to Hand Cross, thence on to Plummer's Plain, 

 turning south-east, past Eastland's Farm, Slut House Farm, Warninglid, Slough Green and 

 Whiteman's Green to Cuckfield, Butler's Green, over the tunnel at Hayward's Heath, taking 

 the road to Wivelsfield by way of Westwood to Ditchling and Westmeston, striking the 

 Downs east of Ditchling Beacon to Falmer, Newmarket Hill and Rottingdean. This 

 district is drained by the Ouse, which has a larger catchment basin than any other in the 

 county, and by its tributaries, the Uckfield, the Black-brook and the Ritch. Mr. J. H. A. 

 Jenner of Lewes, who has given more attention to this district than any other observer, m 

 his 'Notei on the Flora of the South Downs, states that the chalk hills of that neighbourhood are 

 remarkably free from wood, with some few exceptions on the northern slope, and thus differ 

 much from the downs of West Sussex and Kent. There are also cultivated tracts which
