Which of the following is not an example of entomophilous flower?

Guinea grass is not an example of entomophilous flower. Entomophilous flowers are those that are pollinated by insects, such as bees, butterflies, and flies. These flowers are usually brightly colored, have a pleasant fragrance, and produce nectar as a reward for the pollinators. Hibiscus, Flamboyant, and Allamanda are all examples of entomophilous flowers. Guinea grass, on the other hand, is wind-pollinated and does not rely on insects for pollination. Wind-pollinated flowers tend to be small and inconspicuous, with no need for showy petals or fragrant odors. Therefore, Guinea grass is not an example of an entomophilous flower, as it is pollinated by wind rather than insects.
