Pappus (botany) pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word "pappos", Latin "pappus", meaning "old man", so used for a plant (assumed to be an "Erigeron" species) having bristles and also for the woolly, hairy seed of certain plants. Pappus (botany) The pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower heads of the plant family Asteraceae. The term is sometimes used in other plant families such as Asclepiadaceae (milkweeds), whose seeds have a similar
Calyx of Held nucleus of the trapezoid body) and VCN (ventral cochlear nerve), eventually connecting with one another by projecting across the midline of the two areas. These associations begin to appear immediately after VCN neurons have been generated; one can observe the earliest formation of these contacts around embryonic day 17 (E17). These neuronal connections, which make up an important area of the cochlea, form branches with one another that terminate in the calyx of Held. Over the course of the next two to three weeks, the neuronal contacts that first formed the embryonic calyx evolve in shape and function, culminating in
