Tetraploid chromosome counts of n = 20 are reported for two previously cytologically unknown South American species of Chusquea, C. capitulifora and C. scandens. Diploid counts were previously unknown in this genus, but C. talamancensis of Costa Rica has n = 10. No previous chromosome counts were known for the genus Aulonemia nor any other genus of the subtribe Arthrostylidiinae. Aulonemia pumila and A. amplissima from South America are tetraploid with n = 20.
