利用nrDNA的ITS序列对西北太平洋沿岸的一种海熏衣草进行了系统发育分析。结果表明，大洋性大东诸岛居群的ITS序列在9个表型置换上与其它种有显著差异。这一发现表明，西北太平洋岛屿之间的遗传变异的距离独立的地理结构。在L. Wrightii（平均：每年每个位点1.41×10− 8个替换）高于开花植物中任何其他情况下的替换率。
We conducted a molecular phylogenetic analysis of a coastal sea lavender in NW Pacific using ITS sequences of nrDNA. As a result, the ITS sequences of populations on the oceanic Daito Islands were considerably different from conspecific others in nine apomorphic substitutions. This finding indicates a distance-independent geographical structure of the genetic variation among islands in NW Pacific. The calibrated rate of nucleotide substitutions in the ITS regions within L. wrightii (average: 1.41×10−8substitutions per site per year) was higher than any other instances of substitution rates in flowering plants.
