NOTES ON THE FLORA OF EAST SUSSEX. 

 By J. H. A. Jenner. 



The following notes may be of interest as an addition to Mr. 

 F. C. S. Roper's paper in ' Journal of Botany,' December, 1881, 

 p. 369. I have lately given some attention to the Sussex Roses, 

 and have to thank Mr. J. G. Baker for his kindness in looking over 

 and naming specimens. I have also received much assistance from 

 Mr. Geo. Nicholson, of Kew. 



Those species not in Mr. Hemsley's ' Outline ' are distinguished 

 by a *. 0. = Ouse district. C. = Cuckmere. E.R. = East Rother. 

 M. = Medway. 



Clematis Vitalha, L. E.R. district. Occurs at Archer's Wood, 

 near Battle, on a calcareous stratum of the Ashburnham Beds. 



Ranuncuhis Droiietii, Schultz. — Ouse. Marsh ditches, Lewes. 



R. trichophyllus, Chaix. — 0. Marsh ditches, Lewies. 



Barharea prcBcox, Br. — 0. Naturalised on waste ground, Lewes. 



Cardamine amara, L. — 0. Common on the marshes at Hamsey 

 and Barcombe, near Lewes. 



Diplotaxis tenidfoUa, DC. — I cannot find this plant in Sussex. 

 In most, if not all, of the localities given I believe D. muralis var. 

 Bahingtonii has been mistaken for it. 



Cramhe inaritima, L. — Show^n me by the Rev. E. N. Bloomfield, 

 on beach east of Hastings. E.R. 



Erysimum cheirantJioides, L. ; Sisymbrium Sojjliia, L. ; Camelina 

 sativa, Cr. — I have met with all these species near Lewes, growing 

 near granaries or stables. It is by means of foreign corn (which 

 commonly arrives in this country with a large admixture of seeds) 

 that these and other casuals are spread. The year following the 

 "Military Summer Camp" on the Downs at Lewes all these 

 species occurred on the spot, mixed with Anthemis tinctoria, Alyssiim 

 incanwn, &c., the seeds being introduced with the corn on which 

 the horses were fed. 



Cerastium arvense, L. — 0. Abundant in some arable fields on 

 the Downs near Lewes. 



Geranium pyrenaicum, L. — 0. On the railway near Lewes ; 

 doubtless introduced. 



Ehamnus catharticus, L. — 0. Sparingly on the Downs, Lewes. 



Ulex eu-nanus, Forst. — 0. Ringmer, near Lewes. E.R. Com- 

 mon round Battle. M. Crowborough. 



MelilotHs arvensis, Wallr. — 0. Common at Lewes by the 

 river, &c. 



M. alba, Lam. — 0. Casual at Lewes. 



Mcdicayo denticiilata,^Ni\\di. — 0. Seaford and Newhaven. Var. 

 apiculata. — 0. Bishopstone, near Newhaven. 



■^Trifolium hybridum, L. — 0. Near Lewes. M. Eridge Park. 



Lotus tenuis, Kit. — E.R. Camber, near Rye. 



Lathyrus maritimus, Bigel. — E.R. Pett (Rev. E. N. Bloomfield/. 



Prunus doinestica,Ij. — E.R. Near Battle. 0. Hamsey Common,
