A small corolla; a diminutive corolla, or a small petal-like structure in flowers.
From corolla plus the diminutive suffix -et (small), following the pattern of other small botanical structures like leaflet, carpel becoming a corollet.
Botanists use diminutive suffixes like -let and -ule to talk about tiny plant parts—some flowers have such minuscule petals that calling them corollets is more accurate than calling them full corollas.
