Melissa, here. This is why I spend so much time on puzzles, so I can learn words like this (cite):
Ringent:
| 2. | Botany. having widely spread lips, as some corollas. |
[Origin: 1750–60; < L ringent- (s. of ringéns, prp. of ringī to gape), equiv. to ring- open the mouth + -ent- -ent; cf. rictus
]
That is a stunning word, an elegant word -- and one that I cannot wait to use.
