A HISTORY OF KENT 



stations in Kent ; C. ang/ica, L., however is plentiful northwards by 

 tidal rivers and salt marshes. Its var. gemim, Hort {Hortii, Syme), 

 erroneously assumed to be the type in our flora, has occurred about 

 Woolwich and Queenborough, and may be not uncommon. Sisymbrium 

 Sophia, L. is scarce except in the north. Erysimum cheiranthoides, L. 

 may be native here and there on river sides, but is usually a colonist or 

 casual, and rather scarce. Brassica oleracea, L. (wild cabbage) is cer- 

 tainly indigenous on the southern cliffs from Folkestone to the South 

 Foreland ; and B. Sinapioides, Roth {nigra, Koch [black mustard]) is 

 equally so on the coast, though only a colonist inland. Diplotaxis temii- 

 folia, DC. has many natural stations; and D. muralis, DC. (first observed 

 in 1778) has spread from Thanet over many parts of the north and east. 

 Lepidium latifolium, L., though decreasing, still occurs about Upnor, 

 Broadstairs, Sandwich and Folkestone ; L. hirtum, Sm. [Smithii, Hooker), 

 a plant of light soils, is uncommon ; but L. Draba, L. accidentally 

 introduced at Ramsgate about a century ago, has become abundant in 

 many places. Iberis amara, L. (candytuft) used to be found at Shooters 

 Hill, Cobham, Aylesford and Deal. Hutchinsia petraa, planted (by 

 Dillenius .?) on a wall at Eltham, is extinct. Teesdalia mdicaulis, R. Br., 

 abundant on the shingly beach at Lydd and Dungeness, also occurs about 

 Kingsdown, Stourmouth and Cranbrook. Crambe maritima, L. (seakale) 

 is now almost limited to the coast between Walmer and Folkestone. 

 Raphanus maritimus, Sm. has but one station, at Broadstairs. 



VioLACE^. — Viola palustris, L. has its main range in districts 8, 

 9. V. odorata, L. (sweet violet) is certainly native on the chalk. While 

 V. ericetorum, Schrad. {canina, auct.) is fairly general on dry heaths, V. 

 lactea, Sm. has only been observed about Tunbridge Wells, and between 

 Leigh and Penshurst Park. 



PoLYGALE^. — Polygala oxyptera, Reichb. is scarce, P. calcarea, F. 

 Schultz locally abundant, on the downs ; to which also P. austriaca, 

 Crantz (only found outside Kent in one British station) is restricted. It 

 has been gathered near Wye, Charing, Hartlip and Shoreham, and 

 probably occurs elsewhere. 



Frankeniace^. — Fratikenia Icevis, L. (sea heath) may be found 

 here and there from Sheppey to New Romney. 



Caryophylle^. — Dianthus Armeria, L. (Deptford pink), though not 

 rare, is decreasing ; D. deltoides, L. (maiden pink) being very scarce. 

 D. plumarius, L. and D. Caryophyllus, L. (aliens) linger on two or three 

 ruins. D. prolifer, L. is native about Hythe. Silene conica, L. abounds 

 on Deal sandhills and at Romney Warren ; S. anglica, L. being strangely 

 rare, and S. quinquevuhiera, L. merely sporadic. S. nutans, L. (Notting- 

 ham catchfly) has a considerable range in the south-east ; its near ally 

 S. italica, Pers., long known near Dartford, also grows at intervals from 

 Dungeness to St, Margaret's Bay. S. noctijiora, L, is not well established, 

 except in Thanet. Cerastium quaternellum, Fenzl {Mcenchia erecta, Sm.) is 

 local and of uncertain appearance ; but C. arvense, L. occurs frequently 

 on the chalk. Stellaria palustris, Retz {glauca. With.) has been found
