Abstract
The study of herbarium materials of the Ephedra dahurica Turcz. collected in the Torey Lakes region in different years, revealed the morphological variability of its pollen grains. An inverse relationship has been established between the development of the number of furrows and ribs of pollen grains and the values of temperature and humidity during the growing season. During wet seasons, the plant produces pollen grains with few furrows. The number of furrows increases during dry and cool growing seasons.
