Diagnostic characters for each species in ITS, <i>matK, rbcL</i> and <i>trnH-psbA</i>.

Diagnostic characters for each locus were identified with reference to GenBank sequence for the locus of particular species or related species (if not available in the GenBank data base). For ITS, the start of ITS1 of reference sequence was considered as position 1, for matK and rbcL, the first nucleotide of start codon of reference sequence was considered as position 1 and for trnH-psbA, the first position of intergenic spacer of reference sequence was considered as position 1.
