Chromosomal information on 12 species under 8 genera is presented. Genus Diplomeris with a single species (D. hirsuta: 2n=42) is investigated for the first time. Herminium congestum (n=20) and H. duthiei (n=20) are cytologically newly recorded species. Aneuploid number n=18 is noticed in Herminium gramineum. Cytological races are observed in Orchis latifolia (2n=40, 80) and Herminium lanceum (2n=36, 76).
