Original meiotic or mitotic chromosome numbers are reported for the nine species of Acanthophyllum, viz: A. acerosum Sosn. (n=28), A. crassinodum Yukhan. & Edmondson (2n=90), A. elatius Bunge (n=15+1B, 2n=30+1B), A. glandolusum Bunge ex Boiss. (n=90), A. gracile Bunge ex Boiss. (2n=30), A. korshinskyi Schischk. (2n=30), A. microcephalum Boiss. (2n=60), A. pachycephalum Schiman - Czeika (2n=30), A. sordidum Bunge ex Boiss. (2n=60).
