The quality or state of being ampullate or bottle-shaped.
From Latin ampulla + -osity (quality or state of). This rare noun form transforms the adjective into an abstract noun describing the characteristic of having an ampulla-like shape.
Ampullosity is an almost never-used word that botanists and biologists might employ when discussing the swollen, flask-like parts of plants or animals—it's the kind of ultra-specific vocabulary that makes scientific writing fascinating and precise.
