|discussion=<p><i>Echinophyllum sachalinense</i> is best distinguished from similar species by the combination of stem leaves with slender, recurved apices; coarsely serrate-dentate leaf margins often with cilia attached proximally; one massive papilla per laminal cell; branch leaves with a smooth, lanceolate apical cell; paraphyllia with smooth, lanceolate apical cells; and lanceolate, papillose pseudoparaphyllia. This species is known from five localities in North America along the northern Pacific Rim, all discovered since 1992. Specimens from four of the localities are reported by T. J. O’Brien and D. G. Horton (2000); a fifth locality is near Mother Goose Lake in Alaska (W. B. Schofield, pers. comm.).</p>
