Fasciation In Lilies
by IRLS Member  Mary O'Connor
FASCIATION:   a malformation of plant stems commonly manifested as
enlargement and flattening as if several stems were fused.

Fasciation is a relatively rare condition of abnormal growth in growing tip, which
normally is concentrated around a single point but instead becomes elongated
producing flattened, ribbon-like, crested, or elaborately contorted tissue.

Any occurrence of fasciation has several possible causes, including hormonal,
genetic, bacterial, fungal, viral and environmental causes.
