TABLE 3. Karyotype symmetric indices calculated for Allium parhamii and A. monophyllum; CV CL: coefficient of variation of chromosome length, and M CA: mean centromeric asymmetry. The karyotype formula and chromosome data for calculating the indices for A. monophyllum are from Fritsch (2018).

Symmetric indices	Stebbins	CV CL	M CA	Karyotype formula
Allium parhamii	2A	17.70	13.41	2n = 2x = 16 = 12m + 4sm(4SAT) + 1B
Allium monophyllum	1A	11.04	11.83	2n = 2x = 16 = 13m + 3sm(2SAT)
