I've seen cannabis plants that have fasciation, and the fascicles look a bit like "siamese twins".
Fasciation is a condition that may randomly affect a diverse range of plants, including cannabis. Round stems are flattened, suggesting many stems have fused together. True fasciation is the product of a single, normally dome-shaped growing point that has become abnormally broadened and flattened. Any sideshoots usually remain small and undeveloped.
The condition may be caused by random genetic disruption or infection by the bacterium that causes leafy gall disease (Rhodococcus fascians). It can also be initiated chemically or mechanically by, for example, frost action, insects, or damage by chance when hoeing or forking.
