NAKAI-Aug. 1930-typus) -- in the same place (H. HARA)-Aburakoma (II. TIARA) Endemic in Yezo. This species is most closely allied to Rumex odontocarpus to which Prof. NAKAI attributed it as its distinct variety (var. japonicus). As a matter of fact, the general outlook of this species quite harmonizes with the European species, yet the fruits of Japanese species are twice as much larger and broader than the European. Prof. MIYABEreduced this to R. japonicus, but in the latter species the stem is lower and green, the inflorescence is more f oliose, and the valves of the fruits are slightly dentated or nearly entire.
