Iva axillaris
''Iva axillaris'', called povertyweed〔 or death weed,〔 is a North American species of flowering plants in the daisy family. It grows in the western and central United States and in western Canada, from British Columbia south to California and east as far as the western Great Plains in the Texas Panhandle, Nebraska, the Dakotas, and Manitoba.〔(Calflora taxon report, University of California, ''Iva axillaris'' Pursh, povertyweed )〕〔(Biota of North America Program 2014 county distribution map )〕 It has also become established in Australia, where it is considered a weed.〔(Atlas of Living Australia, ''Iva axillaris'' Pursh Death Weed )〕
''Iva axillaris'' is a wind-pollinated herb up to 60 cm (2 feet) tall, spreading by means of underground rhizomes. It has many small, lance-shaped leaves rarely more than 45 mm (1.8 inches) long. Flowers are set in the axils of the leaves rather than congregated at the tips of branches as in related species. Each head can contain 9-12 florets〔(Flora of North America, ''Iva axillaris'' Pursh 1813 )〕〔(Best, K.F. 1975. Biology of Canadian weeds, 10, ''Iva axillaris'' Pursh. Canadian Journal of Plant Science 55:293-301 ) includes photos, distribution map, description, ecological information〕
