Chloroplast DNA restriction site variation in Hemerocallis middendorfii Trautv. and Meyer was investigated to deduce the historical differentiation process that had taken place in populations among three districts Hokkaido, Honshu and the Island of Tobishima in Japan as distinct from the morphological data. The populations selected were eight in total, consisting of two populations from Honshu, one each from the Islands of Sado and Tobishima and four from Hokkaido. Twelve endonuclease restriction enzymes were used. Six restriction site mutations were found among the populations investigated. A single, most parsimonious phylogenetic tree is generated, and revealed that the four populations of Hokkaido and two populations of the Islands of Sado and Tobishima are monophyly, respectively
