Spadix (botany) Typically, the stigmas are no longer receptive when pollen is released which prevents self-fertilization. We also have Compound Spadix Inflorescence in which the axis is branched. Usually whole Inflorescence is covered by a stiff boat shaped path for example- Coconut. Spadix (botany) In botany, a spadix ( ; plural spadices , ) is a type of spike inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known "Anthurium"
Diaspore (botany) Diaspore (botany) In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some seed plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few seed plants, the diaspore is most or all of the plant, and is known as a tumbleweed. Diaspores are common in weedy and ruderal species. Collectively, diaspores, seeds, and spores that have been modified for migration are known as "disseminules". A diaspore of seed plus elaiosome is a common adaptation to seed dispersal by ants (myrmecochory).
