Summary The genus Dilsea Stackhouse (1809, p. 55) currently contains two species, D. carnosa (Schmidel) Kuntze (1898, p. 404) and D. californica (J. Agardh) Kuntze (1891, p. 892); the genus Neodilsea Tokida (1943, p. 96) encompasses six species, N. americana Abbott (1968, p. 187), N. crispata Masuda (1973a, p. 37), N. integra (Kjellman) Zinova (1961, p. 84), N. natashae Lindstrom (1984, p. 29), N. tenuipes Yamada et Mikami in Mikami (1954, p. 83), and N. yendoana Tokida (1943, p. 96). Masuda (1973b, p. 468) described N. integra var. longissima , and Abbott (1982, p. 301) made the combination N. araneosa for Abbotia araneosa Perestenko (1975, p. 1686). I discuss the use of the name Dilsea carnosa rather than D. edulis (Stackhouse) Stackhouse (1809, p. 55) and argue for the reinstatement of Neodilsea integra in Dilsea as D. integra (Kjellman) Rosenvinge (1898, p. 19). Neodilsea longissima (Masuda) comb. nov. is proposed for N. integra var. longissima , and N. borealis (Abbott) comb. nov. is proposed for Schizymenia borealis , an earlier name for N. americana. Neodilsea araneosa is removed from the Dumontiaceae to the Cryptonemiaceae; its correct name is Neoabbottiella araneosa (Perestenko) comb. nov. Lectotypes are designated for D. integra (as Kallymenia ? integra ), N. borealis (as Schizymenia borealis ), and N. yendoana.
