HABITAT: Rocky, sandy, and muddy lakeshores. STATUS: Rare in Canada. NOTES: Primarily restricted to Ontario where it occurs along the shores of Georgian Bay, Lake Erie, and west- ern Lake Ontario. Its only known occurrence in the United States is at one locality in northwestern Pennsyl- vania, but it does not appear on the list of rare plants of that state. This variety differs from var. texanum in having broader leaves ( mm) which vary in shape from elliptic to obovate to oblanceolate on the basal half of the stem. HABITAT: Rives rocailleuses, sablonneuses et boueuses des lacs. SITUATION: Rare au Canada. REMARQUES: Essentiellement limitée à l'Ontario, où on la trouve sur les rives de la Baie Géorgienne, du lac Ãrié et de la partie occidentale du lac Ontario. Aux Ãtats-Unis, on ne l'a repérée qu'en un seul endroit, dans le nord-ouest de la Pennsylvanie, mais elle ne figure pas sur la liste des plantes rares de cet Ãtat. La variété medium se différencie de la variété texanum par des feuilles plus larges (3,3 à 6,0 mm) qui peuvent être de forme elliptique à obovée à oblancéolée sur la moitié inférieure de la tige.
