I have in the 'New Zealand Flora' pointed out the differences between this and its v«n n . 
of Europe, which consist in the larger flower, broader pod, and more slender pedieel. Mr. Gtmn found it origi- 
nally in the wildest and most inaccessible parts of the Island, which, coupled with the fsu-i of its not frequenting 
inhabited places, is good evidence of its being a native, a fact which it- comparatively trilling -peeitic difference from 
so common an English weed as B. pracox would otherwise have led me to doubt. — A tall, robust h< rl>, i 'ightu n
