Original data of pollinator observations, floral traits and plant reproductive success of Prunella vulgaris and Spiranthes sinensis, collected from a plot-level factorial experiment where flowering density of P. vulgaris (high vs. low) was crossed with flowering density of S. sinensis (high vs. low) in the South-East Tibetan Plateau Station for Integrated Observation and Research of Alpine Environment, Chinese Academy of Sciences.In the excel file ‘Data on traits and reproductive success’, each line represents one individual, with data on phenotypic traits and female fitness.In the excel file ‘Data on pollinator visitation’, each line represents one pollinator observation, with data on components of pollinator visitations.
