Sequence variation and species identification ability of six plastid regions in combinations in 86 species of Crocus.

The best combination, i.e., the combination of the fewest number of sequences yielding the highest number of identified species, is marked in bold.最佳组合（即由数量最少的序列构成、可获得最多已鉴定物种的组合）已以加粗形式标记。
