Strobilus(redirected from strobilaceous)
Also found in: Dictionary, Thesaurus.
a sporebearing spikelet on the end of a shoot in many higher plants, including the Lycopodiophyta, Sphenophyl-lales, Calamitales, Equisetum, and Spermatophyta. Strobili bear sporophylls, which are the modified leaves upon which the spore-bearing organs—sporangia—develop. Cones are regarded by some botanists to also be strobili, whereas other botanists believe that they are entire aggregates of strobili (inflorescences).
