Alignment of the spacers between trnS and trnG and rpL20-5’rpS12 in 87 samples from Sabatia kennedyana, representing the northern (NS, Canada), central (MA, USA) and southern (NC, USA) range of the species.

The spacers between trnS and trnG and rpL20-5’rpS12 were aligned with a consensus length of 1161 bp which was reduced to 812 bp after removing gaps and missing data. Among the 87 samples, 28 cpDNA haplotypes harbouring 38 informative sites were identified in 812 bp. Haplotype sequences were deposited in the GenBank database under accession numbers JX003130 –JX003186 for the rpL20-5’rpS12 intergenic spacer and JX003187 – JX003245 for the trnS-trnG intergenic spacer.
