Abstract

Morphological trait variation in populations of rhizomatous (Cypripedium calceolus, Listera ovata) and root-tuber orchid species (Platanthera bifolia, Gymnadenia conopsea) has been studied along a latitudinal gradient in Europe. It has been shown that the structure of shoots changes with transition from the center to the northern or southern periphery of the species range. The reduction in the number of metameres at the range periphery is more distinct in orchids with multimetameric shoots, compared to those with oligometameric shoots. The plasticity of shoot structure observed along the geographic gradient is contingent on climatic factors and can be manifested regionally in cases of long-term temperature deviations. Other morphological parameters, such as shoot height and the sizes of leaves and flowers, can serve as indicators of ecological conditions in habitats.
