Krigia dandelion
Krigia dandelion is known from the Eastern deciduous forest biome and tallgrass prairies. It is unique in propagating extensively by means of tubers. These were well described by T. Holm (1891). All chromosome counts to date have shown 2n = 60, the duodecaploid number based on x = 5.
