Discussion
The history of invasion of Bassia species in North America, together with some details of their distribution, is provided in the treatment by S. L. Collins and W. H. Blackwell (1978). In my opinion, B. hirsuta, unlike B. hyssopifolia, can hardly be regarded as a potentially serious weed because it is confined to highly saline habitats.
