(^1) A revision of data from papers mentioned as References. The numbers of m/sm, microchromosomes, and NF are given
approximately, since it is impossible to discriminate the form and exact number of small chromosomes and microchromosomes. For
octoploid species, the number of telocentrics and microchromosomes is given together because there is no clear size difference
between these two kinds of chromosomes. Usually there are 2–5 middle and/or small-sized telocentric pairs in these karyotypes.
