Syst. Nat. 2: 35. 1821
North America, Asia (Japan).
Species 3 (2 in the flora).
Achlys is of particular interest because of its amphi-Pacific disjunction. Despite the 8000 km or more disjunction, the taxa are remarkably similar in morphology, ecology, and karyology. Japanese populations are diploid; American populations are diploid and tetraploid.
Two species are recognized in this treatment; some researchers prefer to treat them as varieties. In the Californian portion of the range, some field botanists believe the two taxa are sufficiently morphologically distinct to be called species; farther north these differences are reportedly less apparent.
