👉 Parmosiphon, a genus of flowering plants in the family Asteraceae, is known for its unique and rare reproductive structures, which are often described as "parmosiphons." These plants have a tube-like structure that grows from the base of their flowers to form a cone-shaped structure. The parmosiphon contains many tiny, white or yellowish-tinted seeds, which are dispersed by wind or insects and can be found in various parts of the world.
