In botany, describing flowers that have both a calyx and a corolla, the two outer whorls of floral parts that protect and attract pollinators.
From Greek 'di-' (two) + 'chlamys' (cloak/covering) + '-eous' (adjective suffix). This botanical term emerged in 18th-19th century plant classification to distinguish complete flowers.
Dichlamydeous flowers are the 'typical' flowers most people recognize—roses, lilies, and daisies all have both protective sepals and colorful petals, while achlamydeous flowers have neither, like some wind-pollinated plants.
