XOTES SL'PPLEMEXTAL TO THE FLORA OF BKISTOL 15 



it was mistaken for *S'. ColumncB, and Miss Roper forgot to mention 

 that she had it in her herbarium from Portishead Dock in 1909. I 

 am not aware that it has been seen since. >S'. Colunmce is quite a 

 frequent casual on fowl-runs and city refuse. In both species the 

 young pods exceed the flowers, and the foliage is very similar. One 

 or two uppermost leaves of S. ColumncB, howevei*, are usually entire, 

 while those of S. Irio are all divided, and the fruit pedicels of the 

 latter are twice as long as and more slender than those of the other. 

 In both species they are many times shorter than the pods.]
