XVI International Botanical Congess

The inflorescence of Phoradendron consists of two or more squamate internodes, the upper one(s) bearing flowers along their length, in uni-, bi-, or triseriate patterns, and uniquely produced by an intercalary meristem. Prophylls and cataphylls, as they may subtend inflorescences (or, otherwise, vegetative shoots), partly determine may also be axillary to expanded leaves. Rarely, the upper cataphylls also subtend either through abortion of the shoot apex, or through its transformation into an inflorescence.
