日本産海草ウミヒルモ属(トチカガミ科)の分類学的研究 : 形態と分子データを用いた新種Halophila japonica sp. nov.(ヤマトウミヒルモ)の記述と,H.ovalis(ウミヒルモ)の特徴 A Taxonomic Study of the Seagrass Genus Halophila (Hydrocharitaceae) from Japan : Description of a New Species Halophila japonica sp. nov. and Characterization of H. ovalis Using Morphological and Molecular Data
Halophila japonica sp. nov. is described from Japan. Although this entity has long been referred to as H. ovalis, data obtained from detailed morphological examination of field collections and herbarium specimens, geographical distribution records and ITS sequence analyses demonstrate that it is distinguishable from all other members of this genus and can be recognized as a new species. H. japonica is presently reported to occur from Ibusuki (Kagoshima Prefecture, Kyushu region, Japan) in the south, to Mutsu Bay (Aomori Prefecture, Honshu region, Japan) in the north. In order to better characterize H. ovalis materials from Japan, some observations on this species were also provided. As an outcome of this study, there are now four species of Halophila known from Japan: H. ovalis, H. euphlebia, H. decipiens and H. japonica.
