Abstract: | Plantago exhibit great deal of differences in the breeding system. The reproductive effort calculated on the basis of, (i) dry biomass
of foliar and floral parts and (ii) seed output-weight (mg) per unit leaf area (cm2), exhibits relation with breeding system. The predominantly inbreeding taxa invest higher reproductive effort compared to
their outbreeding allies. In terms of sex allocation strategies, the outbreeding species like P. lanceolata, P. lagopus invest more to the development of floral features and to male functions. On the contrary, inbreeding species such as P. patagonica, P. drummondii, and P. ovata invest greater resources to the female function.
