FAQ
Frequently Asked Questions
No, it is an extremely rare and highly specialized term used almost exclusively in scientific contexts like botany and zoology.
A calyx is the outermost whorl of a flower, composed of sepals. A calyculus (or epicalyx) is an additional, secondary whorl of bracts that resembles and sits just below the true calyx.
It would be highly unusual and likely misunderstood, as it refers to a very specific scientific concept unknown to the general public.
The correct plural is 'calyculi', following the Latin neuter noun pattern.
