Abstract. Sumbembayev AA, Abugalieva SI, Danilova AN, Matveyeva EV, Szlachetko DL. 2021. Flower morphometry of members the genus Dactylorhiza Necker ex Nevski (Orchidaceae) from Altai mountains Kazakhstan. Biodiversitas 22: 3545-3555. Several species Kazakhstan have been investigated regarding their morphological flower variability. Significant metric characters were identified allowing to differentiate between four species: D. incarnata, fuchsii, maculata and salina. The morphometric structure flowers was analyzed by comparing 17 parameters in representatives 11 populations. We most variable stable traits as well distinctive features for each species. A high degree diversity revealed principal component analysis Cluster demonstrated population diversity. Structural schemes compiled data photographic processing morphometry, variance ANOVA, variation at level. Useful are provided further taxonomic work on
