Relating to or describing a plant that has seven pistils or female reproductive organs.
From Greek 'hepta' (seven) + 'gynaikos' (female) + '-ous' (full of). An adjective form used in botanical classification and plant description.
Plants use the number of pistils as a survival strategy—more female organs mean more seeds in harsh environments, so heptagynous plants evolved this trait to compete better in crowded habitats!
