Without a calyx; lacking the outer leafy covering (calyx) at the base of a flower.
From Greek 'a-' (without) + 'kalix' (calyx, the cup-like part of a flower). This botanical term was created in Latin and New Latin to describe flowers missing this structural component.
Botanists describe flowers like detectives noticing details—the presence or absence of a calyx is such a basic feature that it's one of the first things plant scientists check when identifying species, making words like 'acale' incredibly useful shorthand.
