Pairwise comparison of the tbcL, under the diagonal, and matK, above the diagonal, sequences for the different species. Percentages of nucleotide identity and gaps are reported. The accession numbers for the sequences are: crocus, KU230342 (rbcL) and KU230351 (matK); curcuma, KU230346 (rbcL) and KU230349 (matK); buddleia, KU230343 (rbcL) and KU230348 (matK); gardenia, KU230345 (rbcL) and KU230347 (matK); safflower, KU230344 (rbcL) and KU230350 (matK). For calendula, we considered the sequences available online in GenBank with Accession Numbers KM356099 (rbcL) and AF151446 (matK).
