Solution

The correct option is B Achlamydeous
A flower is characterised by the calyx and corolla as the non-essential whorls because these are not directly involved in the formation of gametes and fertilization. When these are absent, the flower is called achlamydeous. For example, flowers of willow.
Hence, the correct answer is 'Achlamydeous'
