 the wood, and at Birnbeck. Brean Do^^^l. Abundant

76. C. danica, L.

 observed at New Passage, G,, and at Westou-super- 

 ^lare, 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. Veiy 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. officinalis. V. VI. 



ARMORACIA, Ji/tpp. 



78. A. rUSticana, Ihipp. 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, Kmh. 



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

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