ference between them. A. tenuifolia is said to occur with 
from one to four flowers, whereas A, Capensis is but seldom 
2-flowered ; our specimens, however, scarcely more than five 
inches high, bear but one flower, of exactly the same form, 
but only half the size of those of 4. Capensis, and although 
the narrowness of the segments of the leaves give them 
rather a peculiar aspect, we have little doubt that intermediate | 
forms will be found which will deprive us of all means of 
characterizing, and consequently of separating, the two plants, 
as distinct species.

mature seeds, we cannot decide the question whether this 
species belongs really to Brassica, (of which it has entirely 
the habit), or to Sisymbrium whither it had been referred 
by Thunberg.
