meadow saffron
meadow saffron or autumn crocus, perennial garden ornamental ( Colchicum autumnale ) of the family Liliaceae ( lily family). Native to Europe and N Africa, it has escaped from gardens to meadows and fields in some parts of the United States. Its poisonous corms and seeds were the source of the drug colchicine . The purplish flowers, which bloom in the fall when the leaves are gone, resemble those of the true crocus and true saffron (of the iris family) but have six stamens instead of three. Other species of Colchicum are also popular garden plants. Meadow saffron is classified in the division Magnoliophyta , class Liliopsida, order Liliales, family Liliaceae. |

colchicine
colchicine An alkaloid drug that is obtained from meadow saffron (see COLCHICUM). It has a disruptive effect on microtubular activity (see MICROTUBULE), though not on that of microfilaments. Thus, it affects tissue metabolism generally and mitosis in particular. It can be used to induce polyploidy in plants, because it prevents the development of the spindle and so blocks the separation of chromosomes during mitosis.
