Abstract
Summary: The genusDilseaStackhouse (1809, p. 55) currently contains two species,D. carnosa(Schmidel) Kuntze (1898, p. 404) andD. californica(J. Agardh) Kuntze (1891, p. 892); the genusNeodilseaTokida (1943, p. 96) encompasses six species,N. americanaAbbott (1968, p. 187),N. crispataMasuda (1973a, p. 37),N. integra(Kjellman) Zinova (1961, p. 84),N. natashaeLindstrom (1984, p. 29),N. tenuipesYamada et Mikami in Mikami (1954, p. 83), andN. yendoanaTokida (1943, p. 96). Masuda (1973b, p. 468) describedN. integravar.longissima, and Abbott (1982, p. 301) made the combinationN. araneosaforAbbotia araneosaPerestenko (1975, p. 1686). I discuss the use of the nameDilsea carnosarather thanD. edulis(Stackhouse) Stackhouse (1809, p. 55) and argue for the reinstatement ofNeodilsea integrainDilseaasD. integra(Kjellman) Rosenvinge (1898, p. 19).Neodilsea longissima(Masuda) comb. nov. is proposed forN. integravar.longissima, andN. borealis(Abbott) comb. nov. is proposed forSchizymenia borealis, an earlier name forN. americana. Neodilsea araneosais removed from the Dumontiaceae to the Cryptonemiaceae; its correct name isNeoabbottiella araneosa(Perestenko) comb. nov. Lectotypes are designated forD. integra(asKallymenia?integra),N. borealis(asSchizymenia borealis), andN. yendoana.
