| Note | Many non-Japanese authors regard Gentiana triflora Pallas var. japonica (Kusnezow) Hara and other similar local variations as a synonym of Gentiana triflora Pallas. However most Japanese authors don't agree with such opinion at all. I think that this discussion should be resolved by DNA analyasis of related species. |
