利用rbcL和18S rDNA序列分析，对日本鹿儿岛县、兵库县和神奈川县的喜登兰目（Hildenbrandiales）淡水喜登兰属（Hildenbrandia）植物的遗传多样性进行了研究。系统发育分析结果表明，日本只存在一种淡水希尔登布兰迪亚属植物，即H.日本的。进化枝H.鸡公山黑刺蛾H. japananensis是H. rivularis。Hildenbrandia angolensis是并系的，位于淡水Hildenbrandia分支的基部。此外，H.鸡公山H.根据rbcL和18S序列测定的中国种与日本种的亲缘关系以及种内的形态可塑性，我们认为中国种与日本种是同一种。据此，我们提出了H.鸡公山H.日本的。此外，我们建议对亚洲淡水Hildenbrandia进行更多的分子和形态学研究，以确定H。鸡公山H.在印度有描述。
The genetic diversity of freshwater Hildenbrandia species (Florideophyceae, Hildenbrandiales) from Japan was reassessed based on specimens collected from Kagoshima (Kyushu), Hyogo and Kanagawa Prefectures (Honshu), using rbcL and 18S rDNA sequences. Phylogenetic results suggested the occurrence of only one species of freshwater Hildenbrandia in Japan, H. japananensis. The clade H. jigongshanensis–H. japananensis is sister to H. rivularis. Hildenbrandia angolensis was paraphyletic and positioned basally among the freshwater Hildenbrandia clades. Furthermore, the genetic similarity between H. jigongshanensis and H. japananensis determined by rbcL and 18S sequences as well as the intraspecific morphological plasticity led us to the conclusion that the species from China and Japan were conspecific. Accordingly, we propose the taxonomic lumping of H. jigongshanensis and H. japananensis. In addition, we recommend additional molecular and morphological studies on Asian freshwater Hildenbrandia to determine whether H. jigongshanensis is conspecific with H. ramanaginae previously described from India.
