dichasium
Quick Summary
A dichasium is a type of cymose inflorescence, which is a cluster of flowers on a plant stem. In a dichasium, the main axis produces two lateral branches, each bearing a flower. This structure is characterized by a stunted central flower and two lateral flowers on elongated stalks. The term "dichasium" originates from Greek words meaning "halving" or "splitting in two". This contrasts with a monochasium, which produces only one main axis. Dichasia are considered a unit within a cyme, a broader category of determinate inflorescences where the central flowers open first.123
