A rounded underground storage organ, consisting of the stem base, and often with a fibrous outer layer. It is replaced by the plant annually. E.g Begonias.

Part of a plant stem that stays underground. Stores nutrients for harsh weather

Corms are similar to true bulbs, in that they contain a stem base, but they do not hold the entire baby plant. The roots growing from a basal plate are located on the bottom of the corm. (The basal plate is the base area of the bulb.) The growth point is located on the top of the corm. A corm only lasts for a single season, but a new corm will form [..]

A short, thickened underground storage organ formed usually by enlargement of the base of the main plant stem.

The petals of a flower, collectively.

Thick underground stems, covered by protective leaves, that flower and die in one season

 A thickened underground stem which produces roots, leaves and flowers during the growing season.

a solid, swollen stem whose scales have been reduced to a dry, leaf-like covering; it is similar to a bulb but does not have fleshy scales; gladiolus and crocus are corms

A food-storage organ found in some plants, consisting of a thick, fleshy stem with a papery sheath.

An annual or biennial underground storage structure derived from the stem. Examples of plants having corms include Crocus and Gladiolus, but others are Colchicum and Amorphophallus. Adj. cormous

a bulbous underground stem. Corolla

An underground storage organ consisting of the swollen base of a stem, with roots attached to the underside.

An underground stem that is firm and bulb-like in appearance; it is not divided into scales.

An underground storage organ consisting of the swollen base of a stem with roots attached to the underside. Crocus and gladiolus are examples of plants that form corms. See bulb, tuber, rhizome.

A fleshy, bulb-like underground structure.

 Bulb like portion of the stem of a plant consisting of fleshy tissues not in layers like true bulbs. see pictures of corms and true bulbs.

a short, thick stem that stores nutrients underground. Usually a monocot, it does this through hot summers or cold winters.

A swollen modified stem base with a similar function to that of a bulb (e.g., crocus).

The swollen underground stem of flowers such as crocus or gladiolus. After flowering the old corm

[Roots] -- A short, solid, swollen, usually underground stem or stem base.

(n) solid swollen underground bulb-shaped stem or stem base and serving as a reproductive structure

A short, thickened, upright underground stem.

An underground storage organ consisting of the swollen base of a stem with roots attached to the underside. Crocus and gladiolus are examples of plants that form corms. See bulb, tuber, rhizome.

A corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer [..]

A stem storage organA type of storage organ for storing food for the plant similar to a bulb but consisting of a modified stem or stem base. e.g. Cyclamen.

A thick underground stem that will produce roots, leaves and flowers. A gladiola is an example of a corm.

A rounded, thick modified underground stem base bearing membranous or scaly leaves and buds (gladiolus, crocus, etc).

Unspecified outer tissues of the stem or root.

The swollen base of a plant’s stem serving the same function as a bulb. Crocus and gladiolus "bulbs" are actually corms.
