Table 2: _Cont._variability in the number of flowers per capitula could be explained by the size of the capitula. The most obvious difference is in the size of the roots of _A.P_ var. _pyrethrum_, which has long roots, while those of _A.P_ var. _depressus_ are shorter. The differences observed between the minima and maxima for the studied characters can be explained by the age of the individuals. * Descriptive statistics for quantitative characteristics  
The coefficient of variation (CV) for the 16 quantitative morphological characteristics recorded on the two varieties is presented in Table 4.  
The three least variable characters between individuals of the variety _A.P_ var. _depressus_ are the number of ligulate flowers per capitula (CV = 7.43%), width of tubular flowers (CV = 5.94%), and width of seeds (CV = 8.54%). While the most variable characters are the number of capitula per individual (CV = 33.36%), the number of tubular flowers and seeds per capitula (CV = 33.21%; CV = 25.59%, respectively), and the number of branches per individual (CV = 24.86%), for the variety _A.P_ var. _pyrethrum_, the characters that vary the least between individuals are the length and width of the seeds (CV = 3.79%; CV = 5.52%, respectively) and the length of the tubular and ligulate flowers (CV = 7.93%; CV = 6.67%, respectively). The most variable characters were the number of branches per individual (CV = 31.62%) and the width of ligulate flowers (CV = 24.96%).
