ringent means having the semblance of lips parted wide, such as may be observed in certain flowers.
Why “ringent” is a great word
Having a widely gaping, open-mouthed appearance, especially in botanical description. From Latin ringent-, ringēns, present participle of ringī ("to open the mouth wide, to gape"). Unlike rictus, which denotes a fixed, often grimacing expression, or patulous, which suggests a spreading openness without the specific mouth-like form, ringent is the throat of a foxglove bell inviting the bee, the split-lipped yawn of a snapdragon after a child’s pinch, the silent O of a morning glory at first light—a vulnerable and expectant openness in the static world of petals and stems, the botanical body's unguarded mouth, agape not in horror but in the simple, wordless act of being.
