Table 1. Chromosome numbers in taxa of Poasubg.Secundae
: Explanation note: Chromosome numbers in taxa of Poasubg.Secundae, with RJS' subspecies determinations and original determinations as published or found on herbarium sheets, literature reference, number of counts, voucher collection, country and state or province abbreviation and herbarium where deposited, if known. CI = Carnegie Institution. These numbers show the hexaploid nature of the species complex and the wide and differing ranges of chromosome numbers in each of the P.secunda subspecies.
