Corms serve as organs of food storage and in some plants (e.g., crocus and gladiolus) of asexual reproduction; they are often mistakenly called bulbs.
an underground shoot of a plant with an exterior that resembles a bulb (it is often called a bulb); however, its structure is similar to that of a tuber. The scaly leaves are dry and membranous.
