The Japanese Iris (Hana-shobu) according to Koidzumi (1925), should be correctly known as Iris ensata of Thunberg. For many years it has appeared in bulletins and catalogs as Iris kaempferi. Iris kaempferi sometimes was listed as the same as Iris laevigata but later was seen as distinct from that species. Iris ensata often appears quite similar in the single native forms to Iris laevigata. Maekawa (1967) pointed out that if a leaf of ensata is held to the light one can easily see the distinct lateral vein as a white or silver line. There is one such vein on their secondary dorsal side and two on the counter side, I. laevigata has no such dorsiventrality in its leaves.
