👉 Enneaspermous is a term used in botany that refers to a type of flowering plant. These plants have large, tubular flowers with a single, deep-seated, white or yellowish-tan center. Ennea means "large" and semnos means "seeds." The term was first used by the Dutch naturalist Johannes van Lint in 1734 to describe what he believed were seeds from a type of flowering plant called "Ennea."
