Trimerous flowers are those where the floral appendages are in threes or multiples of three. Flowering plants are actually classified into two categories based on their embryo, called Monocotyledonous (monocot) plants and Dicotyledonous plants. On the other hand, there are some flowers where members of the different whorls are not arranged so uniformly. Linnaea borealis is a variety of twin flower. The monocots are generally characterized by a common trimerous pentacyclic floral Bauplan (Dahlgren et al., 1985). If male and female flowers develop on the same plant as in Cucurbita maxima or maize, the plant is called monoecious. Question 7. The diagram (fig. »Ferns and cycas don’t bear flowers.
