A special preparation method makes it possible to observe the underground bulb movement of Nothoscordum . This movement is effected by contractile roots. Straight ahead movement, which seems to be typical for many bulbous plants, is only exceptionally seen in Nothoscordum . Bulb movement in Nothoscordum occurs by tilting and twisting, effected by the pulling force of contractile roots on one side of the bulb. Also, vegetative dispersal of lateral bulbs (daughter bulbs) caused by the pulling force of contractile roots can be documented. Finally, starting from the seedling, the overall bulb movement can be demonstrated, showing how the plant penetrates the substratum thus reaching the optimum depth.
