For animal-pollinated hermaphrodite plants, the factors that affect floral allocation were usually assigned to extrinsic (environment) and intrinsic ones (resources status). Few studies focused on the effect of rewarding type of plants (pollen vs. nectar and pollen). In this study, we investigated the variation in floral allocation per flower with respect to two distinct rewarding types for pollinators in 12 Pedicularis species in alpine regions, testing for the effects of species, plant size, and elevation simultaneously. The result showed that the rewarding type affected floral allocation significantly, and there was a female-biased floral allocation pattern in nectarless rewarding species relative to nectar and pollen rewarding ones and provided a new insight into variation in floral allocation. It was discussed with respect to activities and foraging behavior of pollinators on the basis of sex allocation theory. Moreover, environmental conditions (elevation) may also play a relatively important role in determining patterns of variation in floral allocation per flower, whereas plant size may not.
