A flower having only one accessory whorl (calyx or corolla or perianth) is called monochlamydeous or haplochlamydeous. 4. Flowering plants are actually classified into two categories based on their embryo, called Monocotyledonous (monocot) plants and Dicotyledonous plants. A typical flower shows the cyclic or whorled type of phyllotaxy. Some Compositae bear hermaphrodite and female flowers on the same plant and these are called gynomonoecious while Veratrum of Liliaceae shows the andromonoecious condition bearing both hermaphrodite and male flowers on the same plant. If staminate, pistillate and hermaphrodite flowers develop on the same plant (as in mango or litchi) it is called polygamous.
