Having a calycule or small cup-like appendages; describing flowers or plants that possess these secondary calyx-like structures outside the main calyx.
From calyculus with the adjectival suffix -ate (meaning 'having' or 'characterized by'). In botanical Latin, -ate endings denote possession of the preceding feature.
When botanists see a flower and say 'oh, that's calyculate,' they're saying 'it has an extra layer of cup-shaped leaves we need to talk about'—it's a shortcut for describing architectural complexity!
