A small cup-shaped structure or appendage; a diminutive calyx, particularly in botanical contexts referring to secondary calyx-like structures found on certain plants.
Latin diminutive form of calyx, using the suffix -culus to indicate a smaller version. This allows precise description of scaled-down versions of larger structures.
The -culus suffix is Latin's way of saying 'little'—so calyculus is literally a 'little cup.' Medieval and Renaissance botanists loved these tiny precise diminutives for describing the intricate details of flowers!
