S. Very luxuriant at Weston-super-Mare, in and about 

 the wood, and at Birnbeck. Brean Down. Abundant 

 on the Cheddar Cliffs. V. VI. 



76. C. danica, L. 



Native; on the shores of the Bristol Channel. Has been 

 observed at New Passage, G., and at Weston-super- 

 Mare, S. It may probably be gathered at many other 

 places on the coast, but will not be found inland. 



IV. VI. 



77. C. anglica, L. 



Native. Very plentiful on the muddy banks of the New 

 Cut and Avon, at and below Bristol. The Bristol 

 plant differs from that figured in E. B. The pods are 

 shorter and broader, with turgid valves, very much con- 

 stricted at the replum. We have never found the leaves 

 to be cordate, nor have we seen any specimen which 

 might be thought intermediate in any degree between 

 this species and C. officindlis. V. VI. 



ARMORACIA, Rupp. 



78. A. rUSticana, Enpp. Horse-radish. 



Alien ; though in some spots it has the appearance of a 

 native. Wherever planted it establishes itself tenaciously, 

 and is sometimes found in deserted garden plots, the 

 sole survivor of ancient cultivation. Frequent about 

 Bristol. V. VI. 



79. A. amphibia, Koch. 



Native ; by water, rare and local. Reported only from 

 Shirehampton, G., and from both banks of the Avon 

 above Bristol. VL VIII. 



CAMELINA, L. 



80. C. sativa, L. 



Alien ; not naturalized, occurring rarely in arable fields.
