Fructification (Latin:
fructificatio
) are the generative parts of the plant (flower and fruit) (as opposed to its vegetative parts: trunk, roots and leaves). Sometimes it is applied more broadly to the generative parts of gymnosperms, ferns, horsetails, and lycophytes, though they produce neither fruit nor flower.
