}}
Krigia biflora, also known as two-flower cynthia or two-flower dwarf dandelion, is a North American species of plants in the sunflower family . It is native to central Canada (Manitoba and Ontario) and to the eastern, central, and southwestern United States.〔(United States Department of Agriculture plants profile )〕〔(Biota of North America Program 2014 county distribution map )〕 Two-flowered Cynthia is rare in Connecticut, and it is listed as a species of special concern.〔(Connecticut Botanical Society )〕
''Krigia biflora'' is an erect perennial growing 18 to 32 inches (450–800 mm) tall. One plant can have 20 or more flower heads, very often 2 per flower stalk, each head with 25-60 yellow to orange-yellow ray flowers about 1 to 1.5 inches (25–38 mm) across. There are no disc flowers. It can become an invasive plant. It grows in a variety of habitats and soils and blooms in late Spring to late Summer. The name of the plant consists of two words: ''Krigia'' for David Krieg, the German physician who first collected this plant in Maryland; and ''biflora'', meaning two-flowered.〔(Wisconsin Plants )〕〔(Flora of North America, ''Krigia biflora'' (Walter) S. F. Blake, 1915. Orange dwarfdandelion )〕
