对小笠原群岛特有种小笠原马齿苋进行了分子系统发育分析、形态学观察和命名学研究。这些结果解决了广泛归化的P. boninensis和P. pilosa之间的争议，表明它们在遗传学和形态学上是不同的。此外，P. boninensis被证明是P. psammotropha的同种种，P. psammotropha迄今为止在中国南部、台湾和菲律宾北方有记录，但在琉球没有记录。P. psammotropha的名称是在保存在K.根据地理分布，沙生贝可能是通过海流传播或通过候鸟的外来和/或末端动物传播而不经过琉球迁移到海外的海洋小笠原群岛。
Molecular phylogenetic analyses, morphological observations, and nomenclatural studies were carried out to investigate the taxonomic status of Portulaca boninensis, endemic species from the Bonin (Ogasawara) Islands (Japan). The results addressed controversy between the widely naturalized P. boninensis and P. pilosa, indicating that they are phylogenetically and morphologically distinct. Furthermore, P. boninensis was showed to be conspecific to P. psammotropha which is until now recorded in southern China, Taiwan, and the northern Philippines, but not in the Ryukyus. The name of P. psammotropha was lectotypified on a specimen preserved at K. Based on phylogeography, P. psammotropha likely migrated to the Oceanic Bonin Islands oversea by sea-current dispersal or by exo-and/or end ozoochory through migratory birds without passing through Ryukyus.
