drawn, were presumably referred to Fumaria longipes, Cosson, owing to that 
plant being originally described as an annual with somewhat similar flowers. 
Their agreement with the account of X. muricaria furnished by Pomel is 
unmistakeable.

This plant appears to differ considerably from the other known annual 
species, and some of its features recall R. tenuifolia. Judging from Pomel's 
knowledge of these plants, however, it is unlikely that he would have 
confused it with a perennial species, although his diagnosis makes no mention 
of its different habit; and the species has therefore been provisionally 
adopted. |
