Because practitioners in the sciences need precision when speaking or writing formally, the botanical term of choice for both true seeds as well as those carrying extra parts is disseminule, a catchall term that covers all variations of reproductive packages, botanically known by terms such as aril, achene, capsule, caryopsis, nut, drupe, and true seed (Figure 4).
The disseminule is elliptical to elongate-elliptical, with semielliptical wings persisting from the strongly winged floral tube of the flower (Gentry, 1993).
According to Carlquist (1974), long-distance dispersal is often not achieved by a single individual or disseminule.

The Galapagos have received most plant-species introductions by avifaunal transport (up to 60%), including fruits, seeds, or vegetative disseminules carried internally or attached externally (Porter 1976).
