elongation of the meristem resulting in irregular phyllotaxis.

The growing together, or fusion, of different parts of a plant. This is where leaves and blooms sometimes fuse together.

A distortion of a plant caused by an injury or infec-tion that results in thin, flattened, and sometimes curved shoots.

Hyperplastic symptoms characterized by a fusing (and flattening) of such plant organs as stems. ( 20)

Fasciation is a condition of plant growth in which the apical meristem, normally concentrated around a single point, producing approximately cylindrical tissue, becomes elongated perpendicularly to the direction of growth, producing flattened, ribbon-like, crested, or elaborately contorted tissue. The phenomenon may occur in the stem, root, fruit, or flower head.
