In botany, a calyx-like appendage or structure that resembles a corolla (flower petals) but is positioned differently, or a crown-like feature on certain flowers.
From 'cata-' (down) + 'corolla' (Latin for little crown, from corona). This technical botanical term describes a modified or atypical petal arrangement.
Botanists have so many precise words for tiny flower parts because bees, beetles, and birds depend on these exact structural details to find nectar—what looks like a simple petal to us is a complex landing platform.
