rangelands throughout North America [8,18,35].  It is widespread in the
United States except along the southern boundary of the western and
south-central states [30].  It has been collected in every province of
Canada except Prince Edward Island, New Brunswick, and Newfoundland [22].  


ECOSYSTEMS :

HABITAT TYPES AND PLANT COMMUNITIES : 
Heart-podded hoary cress is found in saltcedar (Tamarix ramosissima)
communities in Utah; in a study relating plant cover to saltcedar age,
heart-podded hoary cress occurred only in stands 6.0 to 9.6 years old,
with average cover of 25 percent [4].  It occurs in antelope
bitterbrush/rough fescue (Purshia tridentata/Festuca scabrella) and
antelope bitterbrush/bluebunch wheatgrass (Pseudoroegneria spicata)
habitat types in southwestern Montana [10].  In Oregon, heart-podded
hoary cress occurs in basin big sagebrush (Artemesia tridentata ssp.
tridentata) and Wyoming big sagebrush (A. tridentata ssp. wyomingensis)
communities [18,27].
