Two-flowered Cynthia somewhat resembles a common dandelion. It's a perennial with one or few stalks, with few to several branches above the midpoint. Flowerheads orange-yellow, dandelion-like, but somewhat smaller, to 1½ inch across, terminal on stems normally having one clasping leaf midway on the stalk. The botanical name biflora (“two-flowered”) is misleading, as the plant may have any number of flowerheads. Blooms May–August. Basal leaves spoonlike, on a long peduncle; they can be entire, wavy, toothed, or rarely pinnately lobed. Stem leaves one to few, much reduced, clasping.
Similar species: Five Krigia species are recorded for Missouri. Potato dandelion (K. dandelion), like a “true” dandelion, bears only one flowerhead per stem, but the stems are not hollow. Its roots are small, potato-like tubers about ½ inch long. Virginia dwarf dandelion (K. virginica), resembles a miniature dandelion, rarely more than 3 inches tall. It forms large colonies, often lining cracks in rocks.
