On the basis of the frequency of flowering or fruiting in the life time, plants may be either monocarpic or polycarpic. Monocarpic plants are those, in which flowering and fruiting occurs only once in their life, eg, all annual and biennial plants and some perennial plants like bamboo and Agave. In contrast, polycarpic plants bear flowers and fruits repeatedly after attaining maturity, eg, mango. Acacia, Eucalyptus, etc.
